abstract = {Crystals of karwowskiite, Ca9Mg(Fe2+0.5□0.5)(PO4)7, a new mineral of the merrillite group, were found on an amygdule wall in the central part of an anorthite–tridymite–diopside paralava of the Hatrurim Complex, Daba-Siwaqa, Jordan. The amygdule was filled with a sulfide melt, which after crystallization gave a differentiated nodule, consisting of troilite and pentlandite parts and containing tetrataenite and nickelphosphide inclusions. Karwowskiite crystals are colorless, although sometimes a greenish tint is observed. The mineral has a vitreous luster. The microhardness VHN25 is 365 (12), corresponding to 4 on the Mohs hardness scale. Cleavage is not observed, and fracture is conchoidal. The calculated density is 3.085 g/cm3. Karwowskiite is uniaxial (−): ω = 1.638 (3), ε = 1.622 (3) (λ = 589 nm), and pleochroism is not observed. The composition of karwowskiite is described by the empirical formula: Ca9.00(□0.54Fe2+0.23Mg0.12Na0.04 Sr0.03 Ni0.03K0.01) Σ1.00Mg1.00(PO4)7.02. Karwowskiite is distinct from the known minerals of the merrillite subgroup with the general formula A9XM[TO3(Ø)]7, where A = Ca, Na, Sr, and Y; X = Na, Ca, and □; M = Mg, Fe2+, Fe3+, and Mn; T = P; and Ø = O, in that the X site in it is occupied by Fe2+0.5□0.5. Karwowskiite is trigonal, space group R-3c with a = 10.3375 (2) Å},

abstract = {Gorerite, ideally CaAlFe11O19 is a new mineral and M-type hexaferrite of the magnetoplumbite group. It was found in ferrite-rich segregations of esseneite-gehlenite-wollastonite-anorthite melted rock of the 'olive' subunit of pyrometamorphic rocks located near Hatrurim Junction in the Negev Desert, Israel. Within these ferrite-rich segregations up tu 100 μm in size, platy crystals of gorerite up to 50 μm in size intergrow with hibonite, hematite, maghemite, magnesioferrite, dorrite, barioferrite, and andradite, forming aggregates. Additionally, small crystals of gorerite occur within magnesioferrite. Importantly, gorerite did not directly crystallize from the melt. Instead, it emerged through a reaction involving earlier crystallized hibonite and an iron-enriched melt, resulting in the partial or complete replacement of hibonite by gorerite. Gorerite appears grey in the reflected light (R = 18-23%), displaying distinct bireflectance: dark-grey perpendicular to Z, light-grey parallel to Z. Its Raman spectrum exhibits only one strong band at 700 cm-1, which shifts to higher frequencies with increasing Al content. Gorerite crystallizes in the P63/mmc space group, with lattice parameters a = 5.8532(4)Å},

abstract = {Corundum with inclusions of enigmatic super-reduced (SR) minerals was found in mineral separates received as a result of alluvial sediment exploration near Mt Carmel, Israel by the Shefa Yamim Company. This corundum, registered as “Carmel sapphireTM” (CS), has been an object of numerous publications by W. Griffin’s scientific team, in which they propose a questionable hypothesis of CS formation at the crust-mantle boundary with the participation of CH4+H2 fluids. Often the CS is in small fragments of breccia with white cement, which in the opinion of Griffin et al. is a carbonate-cemented volcanic ash. Our investigation of the “white breccia” showed that it consists of unsorted angular fragments of CS from ~1 μm to 7 mm in size cemented by aluminium hydroxides (bauxite) and is a waste product of the fused alumina process, i.e. it has an anthropogenic origin. Phases typical for slags of fused alumina production and metallurgical slags were identified in the “white breccia”. CS has numerous microscopic spherical inclusions of Si-Fe alloy indicating that the removal of Si and Fe from the corundum melt occurred at a temperature above 2000С. Osbornite, TiN, from CS has a chemical zonation characteristic of osbornite from fused alumina with enrichment of central zones in carbon. Comparison of the growth heterogeneity of CS and “electrocorundum” indicates that the crystallization of the corundum melt proceeded in a similar way. Unfortunately, in the case of CS from Carmel locality, the contamination of geological samples with anthropogenic material has led to popularization of biased views. © 2023 Cambridge University Press.

abstract = {Fluoralforsite, ideally Ba5(PO4)3F, (space group P63/m (#176); Z = 2; a = 10.0031(2) Å; c= 7.5382(2) Å and V = 653.23(3) Å3), is a new mineral species of the apatite group - a Ba-analogue of fluorapatite and a F-analogue of alforsite. It was discovered in rankinite paralava filling cracks in pyrometamorphic gehlenite hornfels near the tributary of wadi Zohar and Gurim Anticline, Hatrurim Basin, Negev Desert, Israel. Fluoralforsite occurs in small intergranular spaces between large gehlenite and garnet crystals and in enclaves inside large rankinite crystals with other Ba minerals such as walstromite, zadovite, bennesherite, gurimite, mazorite, barioferrite and baryte. It forms tiny transparent, colourless crystals up to 50 m with a white streak and a vitreous lustre. The cleavage was not observed. It exhibits a brittle tenacity and a conchoidal fracture. The estimated Mohs hardness is 4-4½, and its calculated density is 4.57 g/cm-3. Fluoralforsite is uniaxial (-) with refractive indices (589 nm) nω = 1.689(3) and nɛ = 1.687(3). The empirical crystal-chemical formula for the holotype calculated on the basis of 8 cations is: (Ba3.81Ca0.97Na0.07K0.05Sr0.05Fe0.05)Σ5(P5+2.32V5+0.29S6+0.22Si0.17)Σ3O12(F0.85Cl0.13)Σ0.98. The crystal structure was refined from single-crystal X-ray diffraction data with R1 = 0.0192. The structural investigation indicated an ordered arrangement of Ba/Ca at the M1 site within individual columns running along the c-axis, but a disordered distribution among adjacent columns throughout the structure, which enables the maintenance of the P63/m space group. Fluoralforsite was formed at the final stage of crystallisation as a result of a reaction between the primary mineral assemblages and residual melt. Copyright © The Author(s), 2023.

abstract = {Iron phosphides with significant variations of Cr (up to 18 wt%) and V (up to 8.6 wt%) contents were detected in gehlenite-bearing breccia at the Hatrurim Complex, Negev desert, Israel. Investigations of the composition and structure of the Fe2P phosphides showed that when the V+Cr content is higher than 0.26 apfu (atoms per formula unit), a transition from the hexagonal barringerite (P6¯ 2m) to orthorhombic allabogdanite (Pnma) takes place. According to the experimental data, allabogdanite is a high-pressure (>8 GPa) polymorph of barringerite. Pseudowollastonite associated with Cr-V-bearing allabogdanite is an indicator of phosphide crystallization at high temperature (>1200 °C) and low pressure. Thus, at the low pressure close to ambient, when more than 13 at% Fe in Fe2P is substituted by Cr and V, the orthorhombic polymorph is stable. The orthorhombic phosphide with the highest Cr and V contents belongs to the andreyivanovite species with the FeCrP end-member formula. This is the first finding on Earth of that very rare mineral described from the Kaidun meteorite. Some Cr-V-bearing phosphides have an unusual morphology, which cannot be explained by crystallization from a melt. More probably, these phosphides can form in the process of replacing fish bone remains. We believe that sedimentary protolith was not thermally altered and contained a significant amount of bituminous organic matter and phosphorite inclusions. Injecting paralava into the sedimentary rocks determines the conditions for phosphide formation on the boundary of these rocks as a result of the high-temperature carbothermal reduction process. © 2023 by Mineralogical Society of America.},

abstract = {For the first time, chromium disulphides, known from meteorites, such as caswellsilverite, NaCrS2; grokhovskyite, CuCrS2; and a potentially new mineral, AgCrS2, as well as the products of their alteration, such as schöllhornite, Na0.3CrS2∙H2O, and a potentially new mineral with the formula {Fe0.3(Ba;Ca)0.2} CrS2·0.5H2O, have been found in terrestrial rock. Layered chromium disulphides were found in unusual phosphide-bearing breccia of the pyrometamorphic Hatrurim Complex in the Negev Desert, Israel. The chromium disulphides belong to the central fragment of porous gehlenite paralava cementing altered host rock clasts. The empirical formula of caswellsilverite is (Na0.77Sr0.03Ca0.01)Σ0.81(Cr3+0.79Cr4+0.18V3+0.01 Fe3+0.01)Σ0.99S2·0.1H2O, and the end-member content of NaCrS2 is 76%. It forms single crystals in altered pyrrhotite aggregates. Grokhovskyite has the empirical formula {Cu+0.84Fe3+0.10Ca0.06 Na0.01 Sr0.01Ba0.01}Σ1.03(Cr3+0.94 Fe3+0.05 V3+0.05)Σ1.00S2·0.35H2O, and the CuCrS2 end-member content is 75–80%. A potentially new Ag-bearing chromium disulphide is characterised by the composition (Ag0.89Cu0.07)Σ0.96(Cr0.98 Fe0.03V0.01Ni0.01)Σ1.04S2. Caswellsilverite, grokhovskyite and AgCrS2 form in gehlenite paralava at high temperatures (near 1000 °C) and low pressure under reducing conditions. The structure of the layered chromium disulphides, MCrS2, is characterised by the presence of hexagonal octahedral layers (CrS2)1−, between which M-sites of the monovalent cations Ag, Cu and Na set. A low-temperature alteration of the layered chromium disulphides, when schöllhornite and {Fe0.3(Ba;Ca)0.2}CrS2·0.5H2O form, is reflected in the composition and structural modification of the layer with monovalent cations, whereas the octahedral layer (CrS2)1− remains unchanged. © 2023 by the authors.},

abstract = {Garnets have been known to man since time immemorial and are used in a wide variety of applications as well as being prototypes of useful synthetic materials. Our investigations show that in nature, garnets and minerals with a lan-gasite-type structure can be very close in composition. Examples are cubic Ti-rich garnets with the common formula Ca3(Ti4+;Fe3+;Al)2(Si;Fe3+;Al)3O12 and the new trigonal mineral qeltite, Ca3Ti(Fe3+2Si)Si2O14, which occur in paralavas of the pyrometamorphic Hatrurim Complex, Israel. Synthetic compounds of the langasite family are important because of their functional properties, such as unique piezoelectricity, high thermal stability, and low acoustic losses, as well as optical nonlinearity and multiferroicity. Qeltite is the first high-temperature terrestrial mineral with a langasite-type structure, the description of which was a catalyst for the discovery in pyrometamorphic rocks of the Hatrurim Complex of a whole series of new natural phases with langasite-type structure and varied composition (A3BC3D2O14; where A = Ca and Ba; B = Ti; Nb; Sb; and Zr; C = Ti; Al; Fe; and Si; and D = Si). We think that qeltite and other minerals with langasite-type structure may be relatively widely distributed in terrestrial rocks that form under similar conditions to those of Ti-rich garnet but are missed by researchers. © 2023 Irina Galuskina et al.

abstract = {Garnet supergroup minerals are in the interest of different applications in geology, mineralogy, and petrology and as optical material for material science. The growth twins of natural tetragonal grossular from the Wiluy River, Yakutia, Russia, were investigated using single-crystal X-ray diffraction, optical studies, Raman spectroscopy, microprobe, and scanning electron microscopy. The studied grossular is pseudo-cubic (a = 11.9390 (4); c = 11.9469 (6) Å) and birefringent (0.01). Its structure was refined in the Ia (Formula presented.) d, I41/acd, I41/a, and I (Formula presented.) d space groups. The I41/a space group was chosen as the most possible one due to the absence of violating reflections and ordering of Mg2+ and Fe3+ in two independent octahedral sites, which cause the symmetry breaking according to the group–subgroup relation Ia (Formula presented.) d → I41/a. Octahedral crystals of (H4O4)4−-substituted grossular are merohedrally twinned by twofold axis along [110]. The mechanism of twining growth led to the generation of stacking faults on the (110) plane and results in the formation of crystals with a long prismatic habit. © 2022 by the authors.},

abstract = {Calciolangbeinite, ideally K2Ca2(SO4)3, exists in two modifications, cubic and, first described in the present paper, orthorhombic. They are topologically-similar polymorphs which can be designated as calciolangbeinite-C and calciolangbeinite-O. Calciolangbeinite-O is the first natural orthorhombic langbeinite-like sulfate. It clearly differs from calciolangbeinite-C in the powder X-ray diffraction pattern, optical data and Raman spectrum. Calciolangbeinite-O is found in sublimates of the active Arsenatnaya fumarole at the Tolbachik volcano, Kamchatka, Far Eastern Region, Russia and in pyrometamorphic rocks of the Hatrurim Complex at Jabel Harmun, Judean Desert, Palestinian Autonomy and Har Parsa, Negev Desert, both in Israel. Calciolangbeinite-C is known only in fumarole sublimates at Tolbachik. Calciolangbeinite forms a continuous solid-solution system with langbeinite K2Mg2(SO4)3. The majority of the system is represented by cubic phases, and only members with compositions K2(Ca2.0-1.9Mg0.0-0.1)(SO4)3 have orthorhombic symmetry under room-temperature conditions. The crystal structure of calciolangbeinite-O was studied on a single crystal, chemically very close to K2Ca2(SO4)3, from Tolbachik (R1 = 2.75%). The unit-cell parameters are: a = 10.3330(2)},

abstract = {Osbornite (TiN) is extremely rare in nature (commonly found in enstatite meteorites) and has not yet been identified correctly to form naturally in terrestrial settings. Due to its thermodynamic stability and thermal shock resistance, TiN has wide industrial applications, mainly as coatings. However, as the melting temperature of TiN is very high (~3000°С), coatings are produced at much lower temperatures via physical or chemical vapor deposition. Also, anthropogenic analogues of osbornite are often observed in pyrometallurgical slags. Therefore, it is critical to distinguish between anthropogenic and naturally occurring osbornite. A detailed petrographic study was undertaken on in situ osbornite found within unusual gehlenite-bearing breccias from wadi Zohar, Negev Desert of the pyrometamorphic Hatrurim Complex. The Hatrurim Complex, which extends through Israel, Palestine, and Jordan within the Dead Sea Rift zone, mainly comprises larnite, gehlenite, and spurrite rocks. Osbornite, in close association with iron phosphides, barringerite, and schreibersite, occurs at contacts between gehlenite, paralava, and calcinated clasts of host sedimentary rocks. Based on investigation of pseudowollastonite and Fe-P series phases, osbornite is formed at low pressure, extremely high temperatures (~1200-1500°С), and reduced conditions, following pyrolysis of organic matter contained in the sedimentary protolith. This is the first identification of in situ osbornite in terrestrial rocks and indicates that high-temperature and highly reduced conditions, which are common for meteorites, may occur at/near the Earth’s surface as a result of sustained pyrometamorphism in particular settings. Our findings also provide relevant data and criteria for comparing osbornite occurrences elsewhere and ultimately evaluating their origins © 2022 Evgeny Galuskin et al.

The mineral with the empirical crystal chemical formula (Formula Presented)(P-1; no. 2; a = 19:9366 (2); b = 14:2517 (1); c = 8:89350 (10)Å; α = 88:2480 (1); β = 125:0960 (10); γ = 89:6350 (10); V = 2019:19 (4)Å3; and R = 3:41%) did not show significant differences with respect to that of the type locality. The Raman spectrum of flörkeite is here reported for the first time. No significant differences are noticed compared to phillipsite-K. The main band ~470 cm-1, characteristic of the PHI-type structures, is independent on framework order and Si/Al ratio. The zeolite mineralization of amygdules in pyrometamorphic rocks results from meteoric water circulations in Al-rich rocks during their cooling. The crystallization sequence of zeolite corresponds to the Ca/(K+Na) ratio decrease. Flörkeite formed at the end of a low-temperature crystallization sequence, indicating the predominant role of potassium in crystallization. The occurrence of flörkeite in different pyrometamorphic rocks implies the relatively uniform, regional mineral-forming conditions, and open hydrologic system of zeolitization. In pyrometamorphic rocks of the Hatrurim Basin, the process of zeolitization is characterized by low silica activity and high pH conditions. © 2022 Katarzyna Skrzyńska et al.

abstract = {Keplerite is a new mineral, the Ca-dominant counterpart of the most abundant meteoritic phosphate, which is merrillite. The isomorphous series merrillite-keplerite, Ca9NaMg(PO4)7-Ca9(Ca0.5□0.5) Mg(PO4)7, represents the main reservoir of phosphate phosphorus in the solar system. Both minerals are related by the heterovalent substitution at the B-site of the crystal structure: 2Na+ (merrillite) → Ca2+ + □ (keplerite). The near-end-member keplerite of meteoritic origin occurs in the main-group pallasites and angrites. The detailed description of the mineral is made based on the Na-free type material from the Marjalahti meteorite (the main group pallasite). Terrestrial keplerite was discovered in the pyrometamorphic rocks of the Hatrurim Basin in the northern part of Negev desert, Israel. Keplerite grains in Marjalahti have an ovoidal to cloudy shape and reach 50 μm in size. The mineral is colorless, transparent with a vitreous luster. Cleavage was not observed. In transmitted light, keplerite is colorless and non-pleochroic. Uniaxial (-), ω = 1.622(1), ϵ = 1.619(1). Chemical composition (electron microprobe; wt%): CaO 48.84; MgO 3.90; FeO 1.33; P2O5 46.34, total 100.34. The empirical formula (O = 28 apfu) is Ca9.00(Ca0.33Fe02. +20□0.47)1.00Mg1.04P6.97O28. The ideal formula is Ca9(Ca0.5□0.5)Mg(PO4)7. Keplerite is trigonal, space group R3c, unit-cell parameters refined from single-crystal data are: a = 10.3330(4)},

abstract = {A common attribute of two rare natural chromium-bearing oxides: mcconnellite, CuCrO2, discovered more than 40 years ago in Guyana, and a new mineral ellinaite, CaCr2O4, described from two localities (Brazil and Israel) recently, is that these minerals are poorly studied due to their rarity and small size. Mcconnellite and ellinaite in the present study were found in varicoloured marbles of the pyrometamorphic Hatrurim Complex in the Tulul Al Hammam area, Daba-Siwaqa, Jordan. Structural data obtained for ellinaite (Pnma; a = 9.0875(2); b = 2.9698(1); c = 10.6270(3) Å and V = 286.80(2) Å3), with an empirical formula (Сa1.00Sr0.01)Σ1.01(Cr3+1.79Al0.07Ca0.04Fe3+0.04 Ti4+0.03Mg0.03)Σ2.00O4, is similar to the structural data of synthetic analogue β-CaCr2O4 but differs significantly from the data obtained for ellinaite from Brazil and Israel despite the fact that all the natural phases have a similar composition. Single-crystal X-ray diffraction data for mcconnellite from Jordan (Rm; a = b = 2.9756(1) and c = 17.124(1) Å) with composition (Cu0.98Ca0.03Sr0.01)Σ1.02(Cr3+0.90Al0.05 Fe3+0.03)Σ0.98O2, is the first determination of a natural Cu-delafossite-type structure. This paper also presents the results of a single-crystal Raman study for mcconnellite and ellinaite, which indicates that the spectral features of these minerals is dependent on crystal orientation.

The Daba-Siwaqa area is the largest field of the Hatrurim Complex pyrometamorphic rocks distributed along the rift of the Dead Sea. Priscillagrewite-(Y) and other accessory minerals (such as members of the brownmillerite-srebrodolskite series; fluormayenite; lakargiite; baghdadite; hematite; sphalerite; zincite; garnet of the andradite-grossular series; tululite; vapnikite; minerals of the lime-monteponite series and members of the magnesiochromite-zincochromite series; cuprite; and Y-bearing and Y-free perovskite) are distributed irregularly in varicolored spurrite marble.

The new garnet forms idiomorphic, isometric crystals up to 15 μm in size. It is transparent and has pale yellowish tinge, and its luster is vitreous. Priscillagrewite-(Y) is isotropic: N = 1.96 based on the Gladstone-Dale calculation using a = 12.50 Å and the empirical formula. The Mohs hardness is about 7-7.5. Density calculated from the empirical formula is 4.48 g/cm3. Raman spectrum of priscillagrewite-(Y) is similar to those of other minerals of the bitikleite group and contains the following bands (cm-1): 150, 163, 240, 269, 289, 328, 496, 508, 726, and 785. The strongest lines of the calculated powder diffraction data are as follows [(hkl) dhkl (I)]: (422) 2.552 (100), (642) 1.670 (96), (420) 2.795 (84), (400) 3.125 (72), (200) 4.419 (35), (640) 1.733 (32), and (1042) 1.141 (25). Priscillagrewite-(Y) is interpreted to be a relic of the high-temperature association formed in the progressive stage at the peak pyrometamorphism conditions when temperature could have reached close to 1000 °C. © 2021 Walter de Gruyter GmbH, Berlin/Boston 2021.},

abstract = {The crystal structure of arctite, (Na5Ca)Ca6Ba(PO4)6F3 (R-3m; a ¼ 7.904 A ; s ¼ 41.320 A), was refined in 1984 by E. Sokolova. According to modern concepts, this mineral belongs to the intercalated antiperovskites and is characterized by intercalation of triple antiperovskite layers {[F3(Ca7Na5)](PO4)4}4þ and tetrahedral layers Ba(PO4)2 4–. The pyrometamorphic rocks of the Hatrurim Complex, which are distributed along the Dead Sea Rift, are the origin of eight new minerals with intercalated antiperovskite structures, all discovered within the last five years. Therefore, an update and improvement of the classification and nomenclature was required. The new classification of the arctite supergroup was approved by the CNMNC IMA (Memorandum 95–SM20). The arctite supergroup combines the arctite group (minerals with triple antiperovskite layers), which includes arctite, (Na5Ca)Ca6Ba(PO4)6F3; nabimusaite, KCa12(SiO4)4(SO4)2O2F; dargaite, BaCa12(SiO4)4(SO4)2O3; and ariegilatite, BaCa12(SiO4)4(PO4)2F2O, with the zadovite group (minerals with single antiperovskite layers), which includes zadovite, BaCa6[(SiO4)(PO4)](PO4)2F; aradite, BaCa6[(SiO4)(VO4)](VO4)2F; gazeevite, BaCa6(SiO4)2(SO4)2O; and stracherite, BaCa6(SiO4)2[(PO4)(CO3)]F. Another ungrouped member of the arctite supergroup is aravaite, Ba2Ca18(SiO4)6[(PO4)3(CO3)] F3O – a unique mineral which is formed by the ordered intercalation of super-modules of ariegilatite and stracherite. In addition, a description of aravaite as a new mineral is presented in this paper. The crystal structure has been previously published (Krüger et al. 2018). Furthermore, preliminary data for potentially new minerals of the arctite supergroup, found in rocks of the Hatrurim Complex, are discussed. © 2021 Mineralogical Association of Canada.

The crystal structures of both minerals are refined using synchrotron radiation single-crystal diffraction data. The structure of kahlenbergite (P 63=mmc; a D 5:6486.1/Å; b D 22:8970.3/Å; Z D 2) exhibits triple spinel blocks and so-called R blocks. The spinel blocks show mixed layers with AlO6 octahedra and (Al0:56Fe0:44/O4 tetrahedra and kagome layers with (Al0:92Fe0:08/O6 octahedra. One-dimensional diffuse scattering observed parallel to c*implies stacking faults in the structure. Also; in one of the investigated kahlenbergite crystals additional reflections can be identified; which obviously belong to a second phase with a smaller lattice parameter c: Fe3C-rich hibonite. The structure of hibonite contains the same spinel blocks as kahlenbergite. The R blocks in hibonite contain Ca atoms; AlO5 bipyramids; and AlO6 octahedra; whereas the R blocks in kahlenbergite contain potassium atoms and AlO4 tetrahedra. © 2021 Biljana Krüger et al.},

abstract = {In the last 15 years, zeolite-like mayenite, Ca12 Al14 O33, has attracted significant attention in material science for its variety of potential applications and for its simple composition. Hydrogen plays a key role in processes of electride material synthesis from pristine mayenite: {Ca12 Al14 O32 }2+ (O2 ) → {Ca12 Al14 O32 }2+ (e− )2 . A presence of molecular hydrogen in synthetic mayenite was not confirmed by the direct methods. Spectroscopy investigations of mayenite group mineral fluorkyuygenite, with empirical formula (Ca12.09 Na0.03 )∑12.12(Al13.67 Si0.12 Fe3+ 0.07Ti4+ 0.01)∑12.87O31.96 [F2.02 Cl0.02 (H2 O)3.22 (H2 S)0.15 □0.59 ]∑6.00, show the presence of an unusual band at 4038 cm−1, registered for the first time and related to molecular hydrogen, apart from usual bands responding to vibrations of mayenite framework. The band at 4038 cm−1 corresponding to stretching vibrations of H2 is at lower frequencies in comparison with positions of analogous bands of gaseous H2 (4156 cm−1 ) and H2 adsorbed at active cation sites of zeolites (4050–4100 cm−1 ). This points out relatively strong linking of molecular hydrogen with the fluorkyuygenite framework. An appearance of H2 in the fluorkyuyginite with ideal formula Ca12 Al14 O32 [(H2 O)4 F2 ], which formed after fluormayenite, Ca12 Al14 O32 [□4 F2 ], is connected with its genesis. Fluorkyuygenite was detected in gehlenite fragments within brecciaed pyrometamorphic rock (Hatrurim Basin; Negev Desert; Israel), which contains reduced mineral assemblage of the Fe-P-C system (native iron; schreibersite; barringerite; murashkoite; and cohenite). The origin of phosphide-bearing associations is connected with the effect of highly reduced gases on earlier formed pyrometamorphic rocks. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {Orange greenockite (CdS) aggregates were found in a small fumarole at a burned coal dump near Bytom, Upper Silesia, Poland and were studied using a variety of techniques in order to determine their chemistry, morphology, and most importantly, the mechanism of crystal growth. Greenockite rods, wires, and whiskers with bismuth drops on crystal tops are predominant in these aggregates. Greenockite rods oriented sub-perpendicular to the substrate surface. The rod thickness reaches 5–6 µm and about 10 µm in length. The catalyst bismuth drop has a diameter comparable to the rod thickness. Fiber forms (wires and whiskers) are sub-parallel to the substrate surface. The thickness of these forms is usually less than 2 µm, and the length can be close to 1 mm. The bismuth drop diameter can show a large excess over the fiber thickness. Catalyst drops on the tops of whiskers began to change their form dynamically and exploded, spraying bismuth under the electron beam effect. Rods grow along the [01–10] direction, and whiskers and wires (axial forms) along the [0001] direction. Greenockite rod crystals, carrying on top a relatively homogenous bismuth catalyst drop, were formed on the heated substrate according to the VLS (vapor–liquid–solid) mechanism at temperatures not lower than 270◦ C. Greenockite whiskers and wires grew just above of the substrate surface according to the VQS (vapor–quasiliquid–solid) mechanism at temperatures lower than 200◦ C. These mechanisms of growth have very rarely been recorded to occur in nature and even less so in burning coal dumps. The cooperative growth effects of the fiber greenockite crystals were also described. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {Walstromite, BaCa2Si3O9, known only from metamorphic rocks of North America, was found in small veins of unusual rankinite paralava within gehlenite hornfelses of the Hatrurim Complex, Israel. It was detected at two localities—Gurim Anticline and Zuk Tamrur, Hatrurim Basin, Negev Desert. The structure of Israeli walstromite [with P1 space group and cell parameters a = 6.74874(10)Å; b = 9.62922(11) Å; c = 6.69994(12) Å; α = 69.6585(13)°; β = 102.3446(14)°; γ = 96.8782(11)°; Z = 2; V = 398.314(11) Å3) is analogous to the structure of walstromite from type locality—Rush Creek, eastern Fresno County, California, USA. The Raman spectra of all tree minerals exhibit bands related to stretching symmetric vibrations of Si-O-Si at 650–660 cm−1 and Si-O at 960–990 cm−1 in three-membered rings (Si3O9)6−. This new genetic pyrometamorphic type of walstromite forms out of the differentiated melt portions enriched in Ba, V, S, P, U, K, Na, Ti and F, a residuum after crystallization of rock-forming minerals of the paralava (rankinite; gehlenite-åkermanite-alumoåkermanite; schorlomite-andradite series and wollastonite). Walstromite associates with other Ba-minerals, also products of the residual melt crystallization as zadovite, BaCa6[(SiO4)(PO4)](PO4)2F and gurimite, Ba3(VO4)2. The genesis of unusual barium mineralization in rankinite paralava is discussed. Walstromite is isostructural with minerals—margarosanite, BaCa2Si3O9 and breyite, CaCa2(Si3O9), discovered in 2018. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {A new mineral, siwaqaite, ideally Ca6Al2(CrO4)3(OH)12·26H2O [P31c; Z = 2; a = 11.3640(2) Å; c = 21.4485(2) Å; V = 2398.78(9) Å3], a member of the ettringite group, was discovered in thin veins and small cavities within the spurrite marble at the North Siwaqa complex, Lisdan-Siwaqa Fault, Hashem region, Jordan. This complex belongs to the widespread pyrometamorphic rock of the Hatrurim Complex. The spurrite marble is mainly composed of calcite, fluorapatite, and brownmillerite. Siwaqaite occurs with calcite and minerals of the baryte-hashemite series. It forms hexagonal prismatic crystals up to 250 μm in size, but most common are grain aggregates. Siwaqaite exhibits a canary yellow color and a yellowish-gray streak. The mineral is transparent and has a vitreous luster. It shows perfect cleavage on (1010). Parting or twinning is not observed. The calculated density of siwaqaite is 1.819 g/cm3. Siwaqaite is optically uniaxial (-) with ω = 1.512(2), ϵ = 1.502(2) (589 nm), and non-pleochroic. The empirical formula of the holotype siwaqaite calculated on the basis of 8 framework cations and 26 water molecules is Ca6.01(Al1.87Si0.12)S1.99[(CrO4)1.71(SO4)1.13(SeO4)0.40]S3.24(OH)11.63·26H2O. Xâ'ray diffraction (XRD), Raman, and infrared spectroscopy confirm the presence of OH- groups and H2O molecules and absence of (CO3)2- groups. The crystal structure of this Cr6+-analog of ettringite was solved by direct methods using single-crystal synchrotron XRD data. The structure was refined to an agreement index R1 = 4.54%. The crystal structure of siwaqaite consists of {Ca6[Al(OH)6]2·24H2O}6+ columns with the inter-column space (channels) occupied by (CrO4)2-, (SO4)2-, (SeO4)2-, and (SO3)2- groups and H2O molecules. The tetrahedrally coordinated site occupied by different anion groups is subjected to disordering and rotation of these tetrahedra within the structure. The temperature of siwaqaite formation is not higher than ~70-80 °C, as is evident from the mineral association and as inferred from the formation conditions of the natural and synthetic members of the ettringite group minerals, which are stable at conditions of T < 120 °C and pH = 9.5-13. The name siwaqaite is derived from the name of the holotype locality-Siwaqa area, where the mineral was found. © 2020 Walter de Gruyter GmbH, Berlin/Boston 2020.},

Qatranaite is the natural counterpart of synthetic calcium hexahydroxodizincate dihydrate. It forms colourless or white crystals up to 0.3 mm in size. Qatranaite is associated with cuspidine, sphalerite, Se-bearing thaumasite, afwillite, calcite, srebrodolskite–brownmillerite, spinel–magnesioferrite, spurrite and fluorapatite– fluorellestadite. The new mineral has an irregular fracture; no cleavage or parting were observed. The calculated density of qatranaite is 2.598 g cm3, the microhardness VHN25 = 171 kg mm-2 corresponds to ~3.5 in the Mohs’ hardness scale. The qatranaite structure is formed by hydroxylated pyroxene-like chains [Zn2(OH)6]2-, between which the [Ca(OH2)2]2+ groups are located. The Ca atoms are eight-fold coordinated in [Ca(OH)4(OH2)2] polyhedra which share the four hydroxyl oxygen atoms with the Zn-centred tetrahedra. The main bands in the Raman spectrum of qatranaite are related to vibrations in Zn(OH)24 tetrahedra (cm-1): 297, 344 (v2 + v4); 440, 449, 479 (v1 + v3); 990 (vZn–O–Zn); 1065 (vZn–OH). Strong bands at 3190, 3497 and 3624 cm-1 are assigned to OH stretching vibrations. The strongest diffraction lines are [dhkl;Å(I)]: 6.25 (33), 5.002 (14), 3.992 (23), 3.124 (47), 2.881 (100), 2.723 (28), 2.451 (12), 1.575 (20). Qatranaite crystallization was preceded by a high-temperature alteration of spurrite rocks, reflected in the formation of cuspidine along fractures. The formation of qatranaite-bearing veins resulted from low-temperature (<70 °C) rock alteration by hyper-alkaline solutions. © 2019 E.

The empirical formula of the barioferrite investigated is as follows: (Ba0.85 Ca0.12 Sr0.03)∑1 (Fe3+ 10.72Al0.46 Ti4+ 0.41Mg0.15 Cu2+ 0.09Ca0.08 Zn0.04 Mn2+ 0.03Si0.01)∑11.99 O19. The strongest bands in the Raman spectrum are as follows: 712, 682, 617, 515, 406, and 328 cm−1. The structure of natural barioferrite (P63 /mmc; a = 5.8901(2) Å; c = 23.1235(6) Å; V = 694.75(4) Å3; Z = 2) is identical with the structure of synthetic barium ferrite and can be described as an interstratification of two fundamental blocks: spinel-like S-modules with a cubic stacking sequence and R-modules that have hexagonal stacking. The displacement ellipsoids of the trigonal bipyramidal site show elongation along the [001] direction during heating. As a function of temperature, the mean apical Fe–O bond lengths increase, whereas the equatorial bond lengths decrease, which indicates dynamic disorder at the Fe2 site. © 2018 by the authors.

abstract = {The new mineral sharyginite, Ca3TiFe2O8(P21ma; Z = 2; a = 5.423(2) Å; b = 11.150(8) Å; c = 5.528(2) Å; V = 334.3(3) Å3), a member of the anion deficient perovskite group, was discovered in metacarbonate xenoliths in alkali basalt from the Caspar quarry, Bellerberg volcano, Eifel, Germany. In the holotype specimen, sharyginite is widespread in the contact zone of xenolith with alkali basalt. Sharyginite is associated with fluorellestadite, cuspidine, brownmillerite, rondorfite, larnite and minerals of the chlormayenite-wadalite series. The mineral usually forms flat crystals up to 100 µm in length, which are formed by pinacoids {100}, {010} and {001}. Crystals are flattened on (010). Sharyginite is dark brown, opaque with a brown streak and has a sub-metallic lustre. In reflected light, it is light grey and exhibits rare yellowish-brown internal reflections. The calculated density of sharyginite is 3.943 g·cm-3. The empirical formula calculated on the basis of 8 O apfu is Ca3.00(Fe3+ 1.00Ti4+ 0.86Mn4+ 0.11Zr0.01Cr3+ 0.01Mg0.01)Σ2(Fe3+ 0.76Al0.20Si0.04)Σ1.00O8. The crystal structure of sharyginite, closely related to shulamitite Ca3TiFeAlO8structure, consists of double layers of corner-sharing (Ti; Fe3+) O6octahedra, which are separated by single layers of (Fe3+O4) tetrahedra. We suggest that sharyginite formed after perovskite at high-temperature conditions >1000°C. © 2018 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {Ferrites of K and Ba close in composition to the known synthetic compounds KFe2+2 Fe3+15 O25 and BaMg2Fe3+16 O27 were found in a thin vein, filled with magnesioferrite and khesinite, in pyrometamorphic flamite–gehlenite hornfels of the Hatrurim Complex, Palestinian Autonomy. Both ferrites are characterized by a modular structure composed of 5-layered spinel (S) blocks interstratified with R-blocks. The R-modules of K-ferrite are of the b-alumina type whereas those in Ba-ferrite are of the magnetoplumbite type. Rare grains of K-Ba-ferrite of intermediate composition with the empirical crystal chemical formula (EPMA): (K0:57Ba0:38Na0:05)Σ1(Fe3+14:08Mg1:42Al0:80Zn0:59Ni0:16Ca0:14Cu0:09Mn0:03Ti0:03Si0:02)Σ17:36O25:54, were also discovered. The structure of the natural mixed potassium-barium ferrite was investigated by single-crystal X-ray diffraction. The hexagonal space-group symmetry (P6m2; Z = 2) with a = 5.9137(2) and c = 33.1450(15) Å is different to that (P63/mmc) oftheend-members and yields alternate stacking of b-alumina type KMg2Fe15O25 and magnetoplumbite type BaMg2Fe16O27 “supermodules”, each extending ½ of the unit cell along c. Raman spectroscopic study confirms the mixed character of K-Ba-ferrite structure. K-Ba-ferrite formed at non-equilibrium conditions and may be interpreted as an example of a nano-dissipative structure. © 2018 E. Schweizerbart’sche Verlagsbuchhandlung.},

It was found in a few outcrops of pyrometamorphic rocks of the Hatrurim Complex located in the territories of Israel, Palestine and Jordan. The holotype specimen is an altered spurrite marble from the Negev Desert near Arad city, Israel. Ariegilatite is associated with spurrite, calcite, brownmillerite, shulamitite, CO3-bearing fluorapatite, fluormayenite-fluorkyuygenite and a potentially new mineral, Ba2Ca18(SiO4)6(PO4)3(CO3)F3O. Ariegilatite is overgrown and partially replaced by stracherite, BaCa6(SiO4)2[(PO4)(CO3)]F. The mineral forms flat disc-shaped crystals up to 0.5 mm in size. It is colorless, transparent, with white steaks and vitreous luster. Optically, ariegilatite is uniaxial, negative: ω = 1.650(2), ε = 1.647(2) (λ = 589 nm). The mean composition of the holotype ariegilatite, (Ba0.98K0.01Na0.01)Σ1(Ca11.77Na0.08Fe2+0.06Mn2+0.05Mg0.04)Σ12(Si3.95Al0.03Ti0.02)Σ4(P1.70C0.16Si0.10S6+0.03V0.01)Σ2F2.04O0.96, is close to the end-member formula. The structure of ariegilatite is described as a stacking of the two modules {F2OCa12(SiO4)4}4+ and {Ba(PO4)2}4– along (001). Ariegilatite, as well as associated stracherite, are high-temperature alteration products of minerals of an early clinker-like association. These alterations took place under the influence of pyrometamorphism by-products, such as gases and fluids generated by closely-spaced combustion foci. © 2018 by the authors.

abstract = {Chlormayenite Ca12Al14O32[♦4Cl2] (♦-vacancy) is partially hydrated micro porouss mineral with hydroxide groups situated at various crystallographic sites. There are few mechanisms describing its hydration. The first one assumes Cl- substitution by OH- at the center of the structural cages (W-site). The second one determines the converting a T1O4 tetrahedron to a T1O3(OH)3 octahedron due to the replacement of oxygen at the O2 site by three OH-groups according to the scheme: (O2O2- + W Cl-) → 3 × O2aOH. The third mechanism, not considered so far in the case of zeolite-like minerals, includes the hydroxide incorporation in form of hydrogarnet defect due to the arrangement of tetrahedral (OH)4 in vacant cages. This yields a strong hydrated phase containing even up to 35% of water more than in any currently known mineral applicable to Portland cement. Moreover, water molecules present in different structural cages are stable up to 355 K while dehydroxylation linked to the gradual loss of only 8% of OH- groups according to 3 O2aOH- → O2O2- + W OH- + gH2O occurs at temperature range from 355 K to 598 K. © 2017 The Author(s).},

Dzierżanowskite occurrs in larnite pebbles, which are embedded into low-temperature mineral matrix. Associated minerals are larnite, brownmillerite, fluorellestadite, ye'elimite, gehlenite,periclase, ternesite, nabimusaite, vorlanite, vapnikite, fluor mayenite, fluorkyuygenite, oldhamite, jasmundite, covellite, chalcocite and pyrrhotite. Electron microprobe analyses yield an average composition of Cu 55.25, Fe 0.13, S 27.46 and Ca 16.99 wt.%, total 99.83%. The empirical formula of dzierżanowskite, based on 5 atoms, is estimated as Ca0.98Cu2.02Fe0.01S1.99. Dzierżanowskite forms grains up to 15 μm in size or rims on oldhamite and laminar intergrowths with chalcocite and covellite. Dzierżanowskite is characterized by a dark orange color, a cream streak and submetallic luster. In reflected light it is grey, with a cream tint and characteristic yellow-orange internal reflections. The calculated density of dzierżanowskite is 4.391 g cm-3. Three bands at 300, 103 and 86 cm-1 are observed in the Raman spectrum of dzierżanowskite. The strongest lines of the calculated powder diffraction pattern are [d; Å (I) hkl]: 2.358(100) 102, 1.970(93)110, 3.023(78) 011, 6.523(36) 001, 3.412(28) 100, 1.834(28) 103. Dzierżanowskite was also found in unusual jasmindite rocks, forming small "paleofumaroles" within areas of low-temperature hydrothermal rocks bearing larnite pseudoconglomerates at Jabel Harmun. Dzierżanowskite is a superimposed phase of the high temperature alteration of pyrometamorphic rocks, which were subjected to by-products (melts/fluids and gases) of pyrometamorphism originating in the deeper levels of combustion. © 2017 The Mineralogical Society.},

abstract = {Two wiluite samples from the Wiluy River, Yakutia, Russia have been investigated by means of single-crystal and powder X-ray diffraction, electron microprobe analysis, 1H, 27Al, 11B, and 29Si magic-angle spinning nuclear magnetic resonance (MAS NMR), thermogravimetric analysis (DSC/TGA), X-ray photoelectron spectroscopy (XPS) at the Si2p, Ca2p, Al2p, Mg1s, B1s and Fe2p core levels, 57Fe Mössbauer spectroscopy, infrared (IR) spectroscopy and optical measurements. The crystal structures have been refined in the P4/nnc space group [a = 15.7027(3); c = 11.7008(3) Å; V = 2885.1(1) Å3 for 1 and a = 15.6950(2); c = 11.6787(4) Å; V = 2876.9(1) Å3 for 2] to R1 = 0.022 and R1 = 0.021, respectively. In the crystal structure of wiluite, five-coordinated Y1 site is predominantly occupied by Mg. IR spectra of wiluite substantially different from those of vesuvianite, in particular, by the presence of additional bands in the range 1080‒1415 cm−1, which correspond to symmetric B‒O stretching vibrations of the BO3 3− and BO4 5− groups. According to the MAS NMR data, tetrahedrally coordinated T1 site is occupied by B3+ with minor amounts of Al3+. The general formula of wiluite can be written as follows (Z = 2): Ca19Mg(Al;Mg;Fe;Ti;Mn)12(B;Al;◻)5(Si2O7)4(SiO4)10(O;OH)9O2–3. The diversity of vesuvianite-group minerals is largely determined by the population of the Y1 sites. However, wiluite is characterized by the presence of additional T1 and T2 sites and should be considered as special among other vesuvianite-group minerals. The reasonability of subdivision of the wiluite subgroup within the vesuvianite group is discussed. © 2017, Springer-Verlag Berlin Heidelberg.},

abstract = {Two new barium-bearing minerals: gurimite, Ba3(VO4)2 (IMA2013-032) and hexacelsian, BaAl2Si2O8 (IMA2015-045) were discovered in veins of paralava cutting gehlenite-flamite hornfels located in the Gurim Anticline in the Negev Desert, Israel. Gurimite and hexacelsian occur in oval polymineralic inclusions in paralava and are associated with gehlenite, pseudowollastonite or wollastonite, rankinite, flamite, larnite, schorlomite, andradite, fluorapatite, fluorellestadite, kalsilite, cuspidine, aradite, zadovite and khesinite. Gurimite and hexacelsian form elongate crystals <10 μm thick. The minerals are colourless and transparent with a white streak and vitreous lustre, and have (0001) cleavage, respectively good in gurimite and very good in hexacelsian. Fracture is irregular. Density calculated using empirical formulas gave 5.044 g cm-3 for gurimite and 3.305 g cm-3 for hexacelsian. Mean refractive indexes, 1.945 and 1.561, respectively, were also calculated using the empirical formulas and the Gladstone-Dale relationship. The minerals are uniaxial and nonpleochroic. The following empirical crystal chemical formulae were assigned to holotype gurimite: (Ba2.794K0.092Ca0.084Na0.033Sr0.017)∑3.020(V1.8275+S0.0916+P0.0515+Al0.040Si0.005Fe0.0053+)∑2.017O8, and holotype hexacelsian: (Ba0.911K0.059Ca0.042Na0.010)∑1.022Al1.891Fe3+0.072Si2.034O8. The Raman spectrum of hexacelsian is similar to the one of the synthetic disordered β-BaAl2Si2O8. The Raman spectrum of gurimite is identical to that of synthetic Ba3(VO4)2. The electron back-scattered diffraction (EBSD) pattern of gurimite was fitted to the structure of its synthetic analogue with the cell parameters of R3m},

Larnite, fluorellestadite-fluorapatite, srebrodolskite-brownmillerite andmayenite-supergroup minerals are the main minerals commonly associated with gazeevite. Gazeevite is isostructural with zadovite and aradite; the 1:1 type AB6(TO4)2(TO4)2W, occurs together with the structurally related minerals of the nabimusaite series, 3:1 type AB12(TO4)4(TO4)2W3, where A = Ba, K, Sr...; B=Ca, Na...; T = Si, P, V5+, S6+, Al...; W=O2-, F-. Single antiperovskite layers {[WB6](TO4)2} in the structure type of gazeevite-zadovite and triple {[W3B12] (TO4)4} layers in arctite-nabimusaite are intercalated with single A(TO4) layers. These minerals with an interrupted antiperovskite structure are characterized by a modular layered structure derived from hatrurite, Ca3(SiO4)O. Gazeevite is colourless, transparent, with a white streak and vitreous lustre. Gazeevite is brittle, shows pronounced parting and imperfect cleavage on {001}; it is uniaxial (-), ω = 1.640(3), ϵ = 1.636(2) (λ = 589 nm) and nonpleochroic; Mohs' hardness is ~4.5},

abstract = {Khesinite, Ca4Mg2Fe3+10O4 (Fe3+10Si2)O36, is a new member of the rhönite group of the sapphirine supergroup. Khesinite was discovered in thin veins of paralavas within fine-grained gehlenite rocks (hornfels) of the Hatrurim Complex in the Negev Desert, Israel. Paralavas are composed of rankinite, pseudowollastonite (rarelywollastonite),flamite, kalsilite, cuspidine and members of the solid-solution series: Schorlomite-andradite, gehlenite-ackermanite-"Fe3+-gehlenite", magnesioferrite-spinel and fluorapatite-fluorellestadite. Accessory and rare minerals are represented by baryte, walstromite, fresnoite, vorlanite, barioferrite, hematite, perovskite, gurimite, zadovite, aradite and hexacelsian. Electron-microprobe analysis of the holotype khesinite gives the following empirical formula for 40 oxygens and 28 cations: Ca4 (Fe3+8.528Mg1.635Ca0.898Ti4+0.336Ni2+0.217Mn2+0.155Cr3+0.132Fe2+0.098)∑12 [(Fe3+6.827Al2.506Si2.667)S12O40]. Khesinite is black to dark brown. It has semi-metallic lustre and does not show fluorescence. Cleavage and parting are not observed, fracture is irregular. Khesinite has a Mohs' hardness of 6; microhardness VHN50 is 943 kgmm-2. The calculated density is 4.097 g cm--3. In reflected light khesinite is grey with weak internal brown reflections. Reflectance data for the COM(Commission of Ore Mineralogy; IMA) wavelengths vary from ∼13.4% (470 nm) to ∼11.8% (700 nm). The crystal structure of khesinite [P1 a = 10.5363(1); b = 10.9242(2); c = 9.0612(1) Å; a = 106.340(1)°; b = 95.765(1)°; g = 124.373(1)°; V= 780.54(2)Å3] was refined fromX-ray single-crystal data to R1 = 0.046. The khesinite structure is close to that of the synthetic compounds SFCA and SFCAM. Khesinite crystallized in paralava from melt, sometimes forming isolated crystals, but more commonly reaction rims onmagnesioferrite in associationwith pseudowollastonite and flamite at temperature not lower than 1200 °C. © 2016 E.

abstract = {Czochralskiite, Na4Ca3Mg(PO4)4, is the second new phosphate mineral found in the Morasko IAB-MG iron meteorite. This very rare mineral occurs in phosphate inclusions (nodules) with graphite rims enclosed in the kamacite-taenite matrix of the meteorite. Almost thirty mineral species have been reported from this meteorite (most from various inclusions), including six, possibly eight phosphates (fluorapatite; buchwaldite; brianite; merrillite; moraskoite Na2Mg(PO4)F; chlorapatite and whitlockite), and schreibersite, chromite, enstatite ('bronzite'), kosmochlor, kosmochlor-augite, olivine, albite, orthoclase, quartz, cohenite, nickelphosphide, altaite, troilite, pyrrhotite, sphalerite, daubreelite, djerfisherite, and native Cu. Czochralskiite forms xenomorphic, usually oval grains and amoeboid aggregates, between 0.1 and 0.5 mm in size. It is colourless and transparent, with white streak and vitreous lustre; it shows no fluorescence, it is biaxial (+): a = 1.608(2), β = 1.611(2), = 1.616(2); a = a, β = b, = c; 2V (meas.) = 70o(10), 2V (calc.) = 76°; the dispersion is very weak; Mohs' hardness is 4-5; the fracture is irregular, conchoidal, and no cleavage was observed. The mean of twelve electron-microprobe analyses is (wt%): P2O5 46.28, CaO 27.59, Na2O 20.04, MgO 6.21, FeO 0.32, MnO 0.16, K2O 0.09, total 100.69, leading to the empirical formula Na3.97Ca3.02Mg0.95Mn2+0.01K0.01Fe2+0.03 (P4.00O16). The calculated density based on the empirical formula and the single-crystal structural data is 3.148 g • cm-3. The structure of czochralskiite [Pnma; a = 17.9230(2); b = 10.7280(2); c = 6.7794(1) Å; V = 1303.53(3)Å3; Z = 4] is of the glaserite-type and related to that of buchwaldite and brianite. The strongest diffraction lines of the calculated czochralskiite powder diffraction pattern are [dhkl (I)]: 3.802(48), 3.728(31), 2.726(100), 2.679(63), 2.602(83), 1.901 (44). The Raman spectrum shows the following characteristic bands (cm-1; strong bands underlined): 1119, 1167, 1053, 1039, 1022, 1011, 986, 974, 966, 606, 585, 578 and 441. The Raman data show the absence of H2O and CO2. Czochralskiite is interpreted as a primary phosphate, which crystallized together with graphite and other phosphates inside the nodules. The mineral name honours Jan Czochralski (1885-1953), Polish chemist, crystallographer and metallurgist. © 2016 E. Schweizerbart'sche Verlagsbuchhandlung.},

abstract = {Black prismatic crystals of the new mineral wernerkrauseite, ideally CaFe3+2Mn4+O6 [Pnma; a = 9.0548(2); b = 2.8718(1); c = 10.9908(2) Å; V = 285.80(1) Å3; Z = 8/3], were found in altered xenoliths within alkaline basalts of the Bellerberg volcano, Eifel, Rhineland-Palatinate, Germany. Fluorellestadite, wadalite, andradite-schorlomite, perovskite, gehlenite, magnesioferrite, cuspidine, ettringite-thaumasite, hydrocalumite, jennite, katoite, and portlandite are the main associated minerals. Wernerkrauseite crystals up to 0.5 mm in size show strong submetallic lustre; the streak is black. Wernerkrauseite appears grey in reflected light. Pleochroism is very weak, bireflectance and anisotropy are weak. Reflectance data for the COM wavelengths vary from ∼31 % (400 nm) to ∼19 % (700 nm). The calculated density is 4.66 g/cm3, microhardness VHN25 is 154(5) kg/mm2. Wernerkrauseite is a Ca-deficient structural analogue of harmunite, CaFe2O4, and therefore is one of the four known minerals with post-spinel structures. The empirical chemical formula of the holotype wernerkrauseite is Ca0.994(Fe3+1.057Mn4+1.025Mn3+0.878Mg0.030Al0.016)Σ3.006O6. The end-member chemical formula can also be given on the basis of spinel stoichoimetry (Z = 4): Ca2/3[Fe3+4/3Mn4+2/3]O4, which better reflects its non-stoichiometry. The crystal structure was determined using single-crystal X-ray diffraction (R1 = 0.0233 for 800 observed reflections [I > 2σ(I)]). The diffraction pattern shows evidence of short-range ordering of Ca-vacancies. The strongest diffraction lines of the calculated powder diffraction pattern are [dhkl (I)]: 2.646 (100), 2.450 (77), 2.748 (62), 4.527 (54), 4.698 (44), 1.818 (43), 2.425 (37), 1.778 (30). Raman spectra of wernerkrauseite were measured and analysed in comparison to the spectra of harmunite and marokite, CaMn2O4. Crystallisation of wernerkrauseite took place at temperatures below 850-900°C under high oxygen fugacity. Furthermore, Mn4+-bearing non-stoichiometric harmunite Ca0.862(Fe3+1.719Mn4+0.265Ti4+0.012 Mg0.008)Σ2.004O4 was found at the same locality, which suggests the existence of a continuous solid solution between wernerkrauseite, harmunite and Ca2/3Mn3+4/3Mn4+2/3O4, described by the formula Ca1-x/2(Fe3+; Mn3+)2-xMn4+xO4, with x ranging from 0 to 2/3. © 2016 E.

Zadovite and aradite are colourless, transparent with a white streak, have a vitreous lustre and an uneven fracture. Both minerals are uniaxial (-) with refractive indices (589 nm) ω= 1.711(2), ε = 1.708(2) (zadovite) and ω = 1.784(3), ε = 1.780(3) (aradite). The zadovite structure type comprises two tetrahedral sites, which may host a broad compositional range of atoms such as Si, P, V and S. Results of electron microprobe analyses show a correlation between excess Si4+ and S6+ contents, suggesting the substitution scheme 2(P;V)5+ = Si4+ + S6+ at the tetrahedral sites. This points to the possibility of new minerals isostructural with zadovite with end-member formulae BaCa6(SiO4)2[(PO4)(SO4)]F, BaCa6(SiO4)2[(VO4)(SO4)]F, BaCa6[(SiO4)1.5(SO4)0.5](PO4)2F and BaCa6[(SiO4)1.5(SO4)0.5](VO4)2F. The Raman spectra of aradite and zadovite reflect the varying PO4 (e.g. change of band intensity at ~ 1031 cm-1) and VO4 contents (e.g. change of band intensity at ~835 cm-1). The presence of SO4 leads to an additional Raman band at ~ 997 cm-1. The structure of zadovite-series minerals belonging to the nabimusaite group is characterized by a 1 : 1 alternation of antiperovskite-like ([FCa6](TO4)2}4+ modules and Ba(TO4)42- modules. © 2015 by Walter de Gruyter Berlin/Boston.},

abstract = {The new mineral nabimusaite, KCa12(SiO4)4(SO4)2O2F (R3m; a = 7.1905(4); c = 41.251(3) Å; V = 1847.1(2) Å3; Z = 3), has been discovered in larnite-ye'elimite nodules of pyrometamorphic rocks of the Hatrurim Complex. Nabimusaite is colourless, transparent with awhite streak, has a vitreous lustre and does not show luminescence. It is brittle, but shows pronounced parting and imperfect cleavage along (001). Nabimusaite is uniaxial (-), ω = 1.644(2), ε = 1.640(2) (589 nm), nonpleochroic, Mohs' hardness is ~5 and the calculated density is 3.119 g cm-3. The crystal structure has been solved and refined to R1 = 0.0416. Its artificial analogue is known. The nabimusaite structure may be derived from that of hatrurite, also known as the clinker phase 'alite' (C3S=Ca3SiO5), and is built up by an intercalation of three positively charged hatrurite-like modules of composition [Ca12(SiO4)4O2F]3+ with inserted modules of [K(SO4)2]3-. The hatrurite-like modules in nabimusaite are characterized by octahedrally coordinated anion sites and tetrahedrally coordinated cation sites. The structure is representative of the intercalated antiperovskite type. In contrast to its synthetic analogue, nabimusaite is P-bearing. The shortened bond T-O lengths for one tetrahedral site indicates P preference at the Si2 site, located at the border of the hatrurite-like modules. Significant variations of isomorphous substitutions in nabimusaite suggest the possibility of other isostructural minerals occurring in Nature. It also seems likely that nabimusaite could serve as a prototype for new advanced synthetic materials, given the discovery of two other new minerals in the Hatrurim Complex with related modular structures, placed in the nabimusaite group. These are zadovite and aradite, as described in a companion paper (Galuskin et al.; 2015a). The mineral assemblage and paragenesis of nabimusaite suggests that nabimusaite formed as a result of the reaction of potassium-enriched, sulfate-bearing melt with larnite and ellestadite. This contradicts the isochemical model that pyrometamorphic rocks of the Hatrurim Complex formed relatively fast in a practically dry system. © 2015 by Walter de Gruyter Berlin/Boston.},

abstract = {This paper focuses on X-ray diffraction, X-ray photoelectron and UV-vis spectroscopy of two different (green; orange) rondorfite samples. The differences in the sample color originate from various O/Cl ratios. The orange color was found to be related either to the isomorphic substitution of Fe3+/Al3+ for Mg2+, the presence of atypical [MgO4] tetrahedrons in crystal structure or electronegativity of the sample. The tetrahedron is known to be very prone to accumulation of impurities and substitute atoms. Moreover, the XPS data showed tetrahedrally coordinated Mg2+ and isomorphic substitution of Al3+/Fe3+ for Mg2+, which influences local disordering and the point defects density and distribution. Non-equilibrium chlorine positions inside the crystal cages as well as Ca-Cl bonds have also been found. The XPS measurements as a function of temperature indicate occurrence of a structural transformation at about 770 K which is accompanied by a rotation of silicate tetrahedra within magnesiosilicate pentamer and luminescence disappearance. © 2015 Elsevier Ltd.

abstract = {Moraskoite, a new natural phosphate of composition Na2Mg(PO4)F, has been found in the Morasko IAB-MG iron meteorite. The new phosphate occurs in a graphite-troilite inclusion enclosed in a kamacite-taenite matrix. Associated minerals in the inclusions are chlorapatite, buchwaldite, brianite, merrillite, a new phosphate phase of composition Na4MgCa3(PO4)4, chromite, enstatite (bronzite), kosmochlor, kosmochlor-augite, olivine, albite, orthoclase, quartz, cohenite, schreibersite, nickelphosphide, altaite, pyrrhotite, sphalerite, daubreelite, djerfischerite, whitlockite and native Cu. The inclusions are rimmed by a schreibersite-cohenite halo. Moraskoite forms aggregates up to 1.5 mm in size, with individual grains 20-300 μm across. It is colourless and transparent, with a white streak and vitreous lustre; fluorescence is weak blue in ultraviolet radiation (254 and 360 nm); hardness is 4-5; it has irregular, conchoidal fracture and cleavage is rarely observed. Calculated density (using the empirical formula) is 2.925 g cm-3. The moraskoite structure (Pbcn; a = 5.2117(10); b = 13.711(3); c = 11.665(2) Å; V = 833.6(3) Å3 and Z = 8) is similar to that of its synthetic analogue. The strongest diffraction lines of the moraskoite powder diffraction pattern are as follows (d hkl; I): 3.909(75), 3.382(52), 2.955(90), 2.606(100), 2.571(96), 2.545(68), 1.691 (67). In the Raman spectrum, the following characteristic bands are distinguished (cm-1; strong bands bold): 1114, 1027, 962, 589, 438, 336, 308, 279, 262, 244, 193, 184, 147 and 131. The Raman data prove the absence of H2O and CO2. Moraskoite is interpreted as being a primary phosphate, which crystallized together with graphite, troilite and other accessories inside the nodule. © 2015 Mineralogical Society 2015.},

Fluorchegemite is associated with the high-temperature minerals larnite, edgrewite, wadalite, eltyubyuite, rondorfite, lakargiite, Th-rich kerimasite, and with their alteration products such as bultfonteinite, killalaite, hillebrandite, afwillite, trabzonite, and jennite. Fluorchegemite is colorless, and the streak is white. It forms irregular grains up to 0.2 mm. Fluorchegemite gave the following optical data: biaxial (-), α 1.610(2), β 1.6150(2), γ 1.619(2) (589 nm), 2Vz (meas.) = 80(8)°, 2Vz (calc.) = 84°, Δ = 0.009, dispersion r > v, weak; non-pleochroic. Density (calc.) = 2.91 g cm-3. The micro-hardness VHN (loaded 50 g) ranges between 480 and 511 kg mm-2, with an average value (mean of four measurements) of 499(10) kg mm-2, corresponding to a Mohs hardness of 5.5-6. The main bands in the Raman spectrum of fluorchegemite are at 258, 297, 410, 422, 560, 817, 843, 922, 3539, 3548, and 3552 cm-1. Strong lines of the calculated X-ray diffraction pattern are [d (hkl)I]: 2.531(200)100, 1.905(227)90, 2.718(117)63, 3.013(131)57, 2.991(116)56, 3.636(114)52, 2.832(133)51, 2.699(134)46. The empirical formula of fluorchegemite from the holotype specimen is (Ca7.01Mg0.01)Σ7.02 (Si2.98Ti4+0.01)Σ2.99O12 [F1.40 (OH)0.60]Σ2.00. The Ca-humite minerals often form lens-shaped aggregates within the endoskarn zone. The elongated axis of the lens is oriented subperpendicular to the front of metasomatic replacement (skarn zonality). Lens-shaped aggregates of grains are interpreted as contours of replaced quartz phenocrysts in the ignimbrite. The mechanism of this lens formation is discussed. Moreover, lens-shaped aggregates of hydroxyledgrewite occur as rock-forming minerals in an endoskarn zone of a newly discovered xenolith within the Upper Chegem Caldera. In addition, the second finding of the Ca-humite minerals fluorchegemite and kumtyubeite, in an altered xenolith of the Shadil-Khokh volcano, Southern Ossetia, is reported.},

abstract = {The mayenite supergroup, accepted by the IMA-CNMNC (proposal 13-C), is a new mineral supergroup comprising two groups of minerals isostructural with mayenite (space group No. 220; I43d; a ≈ 12 Å) with the general formula X12T14O32-x(OH)3x[W6-3x]: the mayenite group (oxides) and the wadalite group (silicates), for which the anionic charge over 6 W sites is -2 and -6, respectively. Currently only minerals dominated by end-members with x = 0 and the simplified formula X12T14O32[W6] have been reported. The mayenite group includes four minerals: (1) chlormayenite, Ca12Al14O32[□4Cl2]; (2) chlorkyuygenite, Ca12Al14O32[(H2O)4Cl2]; (3) fluormayenite, Ca12Al14O32[□4F2]; and (4) fluorkyuygenite, Ca12Al14O32[(H2O)4F2]. The wadalite group comprises the two mineral species wadalite, with the end-member formula Ca12Al10Si4O32[Cl6], and eltyubyuite, with the end-member formula Ca12Fe3+10Si4O32[Cl6]. Current research on minerals and synthetic compounds indicates that minerals close to the composition of ideal end-members, such as Ca12Fe3+10Si4O32[F6], Ca12Si9Mg5O32[Cl6] and Ca12Al14O30(OH)6[□6], could be found in Nature. A detailed re-examination of the type specimens of mayenite, originally described as Ca12Al14O33, indicates that Ca12Al14O32[□4Cl2] is its correct end-member formula. Consequently, we are redefining and renaming mayenite as chlormayenite, Ca12Al14O32[□4Cl2], whereas the name mayenite would be reserved for a potential mineral with the end-member composition Ca12Al14O32[□5O]. As a consequence, the mineral brearleyite, Ca12Al14O32[□4Cl2], described in 2011 is identical with chlormayenite and is therefore discredited. By analogy with chlormayenite we changed the name of kyuygenite into chlorkyuygenite. © 2014 E. Schweizerbart';sche Verlagsbuchhandlung.},

abstract = {Eltyubyuite, ideally Ca12Fe3+10Si4O32Cl6, a member of the mayenite supergroup, was originally described from altered xenoliths of the Upper Chegem, northern Caucasus, Russia, and Eifel, Germany, where it forms a solid-solution with wadalite (Ca12Al10Si4O32Cl6). The structure of the holotype was confirmed earlier using electron backscatter diffraction. The larger crystal size of Al-free eltyubyuite from a new occurrence in an altered carbonate-silicate xenolith enclosed in plagiodacites of the Shadil-Khokh volcano, Kel' Plateau, Southern Ossetia, enabled the first direct refinement of the eltyubyuite crystal structure. At this locality, Al-free eltyubyuite occurs in a contact zone of the xenolith, within small veins composed of rusinovite, cuspidine and rondorfite. The structure of the Al-free eltyubyuite crystal (dimensions: 20 x 15 x 10 μm) was refined from X-ray diffraction data to R1 = 0.019. Eltyubyite (cubic; space group I43d; a = 12.2150 (2) Å; V = 1822.55(6) Å3; Z = 2) is isostructural with mayenite. Both tetrahedra are Fe3+-dominant: the T1 site (= 1.848 Å) contains 0.85 Fe3+ and 0.15 Si4+, whereas the T2 site (= 1.766 Å) has 0.59 Fe3+ and 0.41 Si4+. Based on electron microprobe data, the empirical formula of eltyubyuite from Ossetia is Ca12.044(Fe3+10.373Si3.473Ti4+0.067Mn2+0.021Mg0.021)Σ13.956O32Cl5.455. Raman spectroscopy recorded bands with increased half-width due to Fe3+ and Si4+ disorder at the two tetrahedral sites T1 and T2. The Raman bands at 959 and 901 cm-1 have been assigned to Si-O stretching vibrations (ν1 and ν3) of (SiO4)4-. The group of bands at 783 (ν3), 705 (ν1), 450 (ν4), 307 (ν2) cm-1 correspond to Fe-O vibration of (Fe3+O4)5-. © 2014 E. Schweizerbart'sche Verlagsbuchhandlung.},

abstract = {Two new mineral species of the mayenite group, fluormayenite Ca12Al14O32[□4F2] (I43d; a = 11.9894(2) Å; V = 1723.42(5) Å3; Z = 2) and fluorkyuygenite Ca12Al14O32[(H2O)4F2] (I43d; a = 11.966(2) Å; V = 1713.4(1) Å3; Z = 2), are major constituents of larnite pyrometamorphic rocks of the Hatrurim Complex (Mottled Zone) distributed along the Dead Sea rift on the territory of Israel, Palestinian Autonomy and Jordan. Holotype specimens of fluormayenite and fluorkyuygenite were collected at the Jabel Harmun, Judean Mts., Palestinian Autonomy and in the Hatrurim Basin, Negev Desert, Israel, respectively. Mineral associations of holotype fluormayenite and fluorkyuygenite are similar and include larnite, shulamitite, Cr-containing spinel-magnesioferrite series, ye'elimite, fluorapatite-fluorellestadite, periclase, brownmillerite, oldhamite as well as the retrograde phases portlandite, hematite, hillebrandite, afwillite, foshagite, ettringite, katoite and hydrocalumite. Fluormayenite and fluorkyuygenite crystals, usually < 20 μm in size, are colourless, in places with greenish or yellowish tint, the streak is white. Both minerals are transparent with a vitreous lustre; they do not show fluorescence. Fluormayenite and fluorkyuygenite are isotropic and have similar refractive indices: n = 1.612(3) and n = 1.610(3) (589 nm), respectively. The hardness of fluormayenite and fluorkyuygenite is H (Mohs) 51/2-6; VHN load 50 g, 771(38) kg mm-2; and 5-51/2; VHN load 50 g, 712(83) kg m-2, respectively. Both minerals have the microporous tetrahedral framework structure characteristic of the mayenite supergroup. In fluormayenite 1/3 of the structural cages are occupied by fluorine. In fluorkyuygenite, in addition to fluorine and negligible amounts of OH, H2O molecules occupy about 2/3 of the cages. The holotype fluormayenite from Jabel Harmun has the crystal chemical formula (Ca11.951Na0.037)Σ11.987(Al13.675Fe3+0.270Mg0.040Si0.009P0.005S6+0.013)Σ14.013 O31.503(OH)1.492[□4.581F1.375Cl0.044]Σ6, fluorkyuygenite from the Hatrurim Basin has the composition Ca12.034(Al13.344Fe3+0.398 Si0.224)Σ13.966O32[(H2O)3.810F1.894 (OH)0.296]Σ6. Raman spectra of fluormayenite and fluorkyuygenite in the spectral region 200-1000 cm-1 are similar and are characterized by the four strong main bands at about 320 (ν2 AlO4), 520 (ν4 AlO4), 700, 770 (ν1 AlO4) cm-1. In the O-H vibration region fluorkyuygenite shows a broad band between 2600-3500 cm-1 (νH2O). The molecular water is completely released from the fluorkyuygenite structure at about 400°C. Fluorkyuygenite crystallized initially as fluormayenite, which later was altered under influence of water vapour-enriched gases during a combustion process. Fluormayenite has been synthesized and fluorkyuygenite is an analogue of the recently discovered chlorkyuygenite, Ca12Al14O32[(H2O)4Cl2], from the Northern Caucasus, Russia. © 2014 E.

abstract = {Unique stone-tool factories have been recognized in the Hatrurim Basin, at one of the largest localities of combustion metamorphic rocks of the Hatrurim Complex (Israel and Jordan). Larnite-rich rocks formed along the western side of the Dead Sea Transform Fault in Israel by combustion of hydrocarbon gas at temperatures between 975-1000 °C and 1300-1380 °C, and baking of hydrothermally altered chalky-marly rocks of the sedimentary sequence. These larnite-rich rocks were favored by hominids to produce stone axes and adzes. Abundant supplies of extremely dense, hard larnite-rich rocks and numerous stone-tool workshops in this part of the Hatrurim Basin suggest production on an industrial scale. The main mineral species of the bifacial tools are larnite, ye'elimite, gehlenite, brownmillerite, fluorapatite, fluorellestadite, rankinite, kyuygenite, and silicocarnotite. For the larnite-rich stone tools, we determined densities between 3.09 and 3.26 g/cm3 and elastic moduli between 100 and 145 GPa, which makes these rocks the densest and strongest rocks in the Levant. We are surprised by the skillfulness and intelligence of hominids who managed to use such tough material for stone-tool production. Recognizing similar axes and adzes in stone-tool collections around the world will unambiguously indicate their source from the Hatrurim Basin, and may clarify whether the bifacial tools are Paleolithic or Neolithic. © 2015 Elsevier B.V.

The calculated density is 5.322 g cm-3, the microhardness is VHN25 = 534 kg mm -2 (mean of seven measurements) corresponding to the hardness of ∼5 on the Mohs scale. The crystal structure of vapnikite Ca 3UO6 differs from that of its synthetic analogue β-Ca3UO6 by having a larger degree of Ca, U disorder. Vapnikite formed at the high-temperature retrograde stage of pyrometamorphism when larnite rocks were altered by fluids/melts of high alkalinity. © 2014 The Mineralogical Society.},

abstract = {Harmunite, naturally occurring calcium ferrite CaFe2O 4, was discovered in the Hatrurim Complex of pyrometamorphic larnite rocks close to the Jabel Harmun, the Judean Desert, West Bank, Palestinian Autonomy, Israel. The new mineral occurs in larnite pebbles of the pseudo-conglomerate, the cement of which consists of intensely altered larnite-bearing rocks. Srebrodolskite, magnesioferrite, and harmunite are intergrown forming black porous aggregates to the central part of the pebbles. Larnite, fluorellestadite, ye'elimite, fluormayenite, gehlenite, ternesite, and calciolangbeinite are the main associated minerals. Empirical crystal chemical formula of harmunite from type specimen is as follows Ca1.013(Fe 31+957Al0 015Cr3+ 0.011Ti4+0.004 Mg0 003)Σ 1 993O4. Calculated density is 4.404 g/cm3, microhardness VHN50 is 655 kg/mm2. The Raman spectrum of harmunite is similar to that of the synthetic analog. Harmunite in hand specimen is black and under reflected plane-polarized light is light gray with red internal reflections. Reflectance data for the COM wavelengths vary from ∼22% (400 nm) to ∼18% (700 nm). The crystal structure of harmunite [Pnma; a = 9.2183(3); b = 3.0175(1); c = 10.6934(4) Å; Z = 4; V = 297.45(2) Å3], analogous to the synthetic counterpart, was refined from X-ray single-crystal data to R1 = 0.0262. The structure of CaFe2O4 consist of two symmetrically independent FeO 6 octahedra connected over common edges, forming double rutile-type 1∞[Fe2O6] chains. Four such double chains are further linked by common oxygen corners creating a tunnel-structure with large trigonal prismatic cavities occupied by Ca along [001]. The strongest diffraction lines are as follows [dhkl; (I)]: 2.6632(100), 2.5244(60), 2.6697(52), 1.8335(40), 2.5225(35), 2.2318(34), 1.8307(27), 1.5098 (19). Crystallization of harmunite takes place in the presence of sulfate melt.},

abstract = {Irinarassite, Ca3Sn2SiAl2O12, a new mineral species of the garnet supergroup was discovered in metasomatically altered carbonate-silicate xenoliths in ignimbrites of the Upper Chegem Caldera, Northern Caucasus, Kabardino-Balkaria, Russia. It occurs as small zones and irregular spots in kimzeyite-kerimasite or rarely as single crystals not exceeding 10 μm in size, within complex pseudomorphs after zircon. Lakargiite, tazheranite, baddeleyite, kerimasite, kimzeyite, baghdadite and rarely magnesioferrite are associated with irinarassite in the pseudomorphs which are confined to larnite-cuspidine zones immediately adjoining the ignimbrite. Larnite, cuspidine, rondorfite, fluor-and hydroxylellestadite, fluorite and secondary minerals such as ettringite, hillebrandite and bultfonteinite are associated with irinarassite. Irinarassite is pale brown to yellow colour. The mineral is characterized by the absence of cleavage and by an irregular fracture. The calculated density is 4.3 g cm-1. The mineral is isotropic with a calculated refractive index of 1.9. The empirical crystal chemical formula of irinarassite from the holotype specimen is as follows (Ca2.965Fe2+ 0.035) Σ3(Sn1.016Zr0.410Ti 0.262Sb5+ 0.237Fe2+ 0.035U6+ 0.017Sc0.014Hf 0.006Nb0.004)Σ2.001(Al 1.386Fe3+ 0.804Si0.446Ti 4+ 0.364)Σ3O12. Electron backscatter diffraction patterns of irinarassite are fitted to the garnet model with a = 12.50(3) Å with excellent MAD (mean angular deviation) = 0.16. The Raman spectrum of irinarassite is analogous to those of kerimasite and other Zr-Sn-garnets of the schorlomite and bitikleite groups. © 2013 Mineralogical Society.},

abstract = {Raman and infrared spectra of rondorfite Ca8Mg(SiO 4)4Cl2, a calcium chlorosilica mineral containing magnesium in tetrahedral position, has been studied in terms of spectra-structure relations. Raman spectra have been measured at different excited laser lines: 780 nm, 532 nm, 488 nm and 457 nm. This mineral is characterized by a single sharp intense Raman band at 863 cm-1 assigned to the ν1 [SiO4]4- (Ag) symmetric stretching mode in the magnesiosilicate pentamer. Due to symmetry restriction the other Raman bands have a small intensity. Two Raman bands observed at 564 cm-1 and 526 cm-1 are associated simultaneously with ν4 [MgO4]6- and ν4 [SiO4]4- symmetric and antisymmetric modes where magnesium occurs in the tetrahedral configuration. The weak bands at 422 cm-1 and 386 cm-1 are associated with the ν2 bending mode of CaO6 in octahedral configuration, respectively. Moreover the infrared spectrum shows very weak bands associated with the hydroxyl group and/or water molecule. Additionally, the strong fluorescence phenomenon was observed and related to the presence of chlorine atoms, magnesium Mg2+ ions in atypical configuration or point defects. © 2012 Published by Elsevier B.V.

abstract = {Dzhuluite, Ca3SbSnFe3+3O12 (Ia3d; a = 12.536(3) ; V = 1970.05(9) 3; Z = 8), a new antimony garnet of the bitikleitegroup, was discovered in a kumtyubeite zone in close proximity to the contact with unaltered ignimbrite in a skarn xenolith from the Upper Chegem Caldera, Northern Caucasus, Russia. The empirical formula of the holotype dzhuluite is (Ca2.954Fe3+0.043Mg0.003)P3.000 (Sn0.850Sb5+0.764Zr0.121U6+0. 127Ti4+0.070Sc0.009Nb5+0.058Hf0.001)P2.001(Fe3+2.051Al0.653Fe 2+0.182 Ti4+0.087Si0.028)P3.001O12. Associated minerals are kumtyubeite, cuspidine, fluorchegemite, larnite, fluorite, wadalite, rondorfite, hydroxylellestadite, perovskite, lakargiite, kerimasite, elbrusite, srebrodolskite, bultfonteinite, ettringite group minerals, hillebrandite, afwillite, tobermorite-like minerals, hydrocalumite and hydrogrossular. Dzhuluite forms poikilitic crystals,50 mmin size that are lightyellow to dark-brown and with a creamy streak. The lustre is strongly vitreous. The calculated density of dzhuluite ranges from 4.708 to 4.750 g/cm3. Raman spectra are analogous to those of kimzeyite, kerimasite and other bitikleite-group minerals. Dzhuluite formed at high temperature during a retrograde stage of primary rock alteration in the larnite subfacies (sanidinite facies) as a result of fluorine metasomatism. © 2013 E.

abstract = {The garnet supergroup includes all minerals isostructural with garnet regardless of what elements occupy the four atomic sites, i.e., the supergroup includes several chemical classes. There are presently 32 approved species, with an additional 5 possible species needing further study to be approved. The general formula for the garnet supergroup minerals is {X3}[Y2](Z3)?12, where X, Y, and Z refer to dodecahedral, octahedral, and tetrahedral sites, respectively, and ? is O, OH, or F. Most garnets are cubic, space group Ia3d (no. 230), but two OH-bearing species (henritermierite and holtstamite) have tetragonal symmetry, space group, I41/acd (no. 142), and their X, Z, and ? sites are split into more symmetrically unique atomic positions. Total charge at the Z site and symmetry are criteria for distinguishing groups, whereas the dominant-constituent and dominant-valency rules are critical in identifying species. Twenty-nine species belong to one of five groups: the tetragonal henritermierite group and the isometric bitikleite, schorlomite, garnet, and berzeliite groups with a total charge at Z of 8 (silicate), 9 (oxide), 10 (silicate), 12 (silicate), and 15 (vanadate; arsenate), respectively. Three species are single representatives of potential groups in which Z is vacant or occupied by monovalent (halide; hydroxide) or divalent cations (oxide). We recommend that suffixes (other than Levinson modifiers) not be used in naming minerals in the garnet supergroup. Existing names with suffixes have been replaced with new root names where necessary: bitikleite-(SnAl) to bitikleite, bitikleite-(SnFe) to dzhuluite, bitikleite-(ZrFe) to usturite, and elbrusite-(Zr) to elbrusite. The name hibschite has been discredited in favor of grossular as Si is the dominant cation at the Z site. Twenty-one end-members have been reported as subordinate components in minerals of the garnet supergroup of which six have been reported in amounts up to 20 mol% or more, and, thus, there is potential for more species to be discovered in the garnet supergroup. The nomenclature outlined in this report has been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (Voting Proposal 11-D).},

abstract = {New electron-microprobe analyses of mayenite from the Ettringer Bellerberg volcano near Mayen in the Eifel district, Germany have high Cl contents and Raman spectroscopy indicates the presence of OH groups. Neither of these components is included in the generally accepted chemical formula, Ca 12Al14O33. A refinement of the crystal structure by single-crystal X-ray methods reveals a previously unrecognized partial substitution. The O2 site which forms one of the apices of an AlO 4 tetrahedron (with 3 × O1 sites) is replaced by 3 × O2a sites, which change the coordination of the central Al atom from tetrahedral to octahedral. This substitution is related to partial hydration of Ca 12Al14O32Cl2 according to the isomorphic scheme (O2- + Cl-) → 3(OH)-. The revised composition of Eifel mayenite is best described by the formula Ca12Al14O32-xCl2-x(OH)3x (x ∼0.75); the original formula, Ca12Al14O 33, is inadequate. The analysed mineral can be considered to consist of endmember Ca12Al14O32Cl2 (62.5 mol.%) and endmember Ca12Al14O30(OH) 6 (37.5 mol.%). © 2012 Mineralogical Society.},

abstract = {Megawite is a perovskite-group mineral with an ideal formula CaSnO 3 that was discovered in altered silicate-carbonate xenoliths in the Upper Chegem caldera, Kabardino-Balkaria, Northern Caucasus, Russia. Megawite occurs in ignimbrite, where it forms by contact metamorphism at a temperature >800°C and low pressure. The name megawite honours the British crystallographer Helen Dick Megaw (1907-2002) who did pioneering research on perovskite-group minerals. Megawite is associated with spurrite, reinhardbraunsite, rondorfite, wadalite, srebrodolskite, lakargiite, perovskite, kerimasite, elbrusite-(Zr), periclase, hydroxylellestadite, hydrogrossular, ettringite-group minerals, afwillite, hydrocalumite and brucite. Megawite forms pale yellow or colourless crystals up to 15 μm on edge with pseudo-cubic and pseudo-cuboctahedral habits. The calculated density and average refractive index are 5.06 g cm -3 and 1.89, respectively. Megawite is Zr-rich and usually crystallizes on lakargiite, CaZrO 3. The main bands in the Raman spectrum of megawite are at: 159, 183, 262, 283, 355, 443, 474, 557 and 705 cm -1. The unit-cell parameters and space group of megawite, derived from electron back scattered diffraction, are: α = 5.555(3)},

abstract = {Dellaite crystals of close to end-member composition, Ca 6(Si2O7)(SiO4)(OH)2, and with ∼1.5 wt.% Cl, yielding Ca6(Si2O 7)(SiO4)(OH)1.75Cl0.25 have been found in skarns within the gabbroid rocks of the Birkhin complex (Eastern Siberia; Russia). The greatest Cl content analysed in a dellaite domain in this skarn is 5.2 wt.% Cl corresponding to 0.8 Cl p.f.u. Dellaite occurs in altered merwinite-larnite-bredigite-gehlenite skarns and also in calcio-olivine skarns with residual larnite. The crystal structures of Cl-free and Cl-bearing (∼1.5 wt.% Cl) dellaite have been refined, including hydrogen positions, from single crystal X-ray data to R 1 = 3.7 and 3.8%, respectively. In addition, both dellaite varieties were studied by Raman spectroscopy indicating stronger hydrogen bonds for the Cl-bearing sample, which agrees with the structural data. Cl is strongly selective and enriches at one (O6) of the two OH positions allowing for the formation of a stronger hydrogen bond O8-H8•••Cl6 compared to O8-H8•••O6. Raman spectra of the domain with ∼0.8 Cl p.f.u. confirm the general enhancement of a low-frequency band in the OH range suggesting the dominance of the O-H•••Cl hydrogen bond systems. Dellaite and killalaite, Ca 3.2(H0.6Si2O7)(OH), have related modular structures, differentiated only by the Si2O7 units in killalaite and alternating Si2O7 and SiO4 units in dellaite. The similarity in cell dimensions and chemical composition suggests that trabzonite, Ca4Si3O10• 2H2O, with Si3O10 trimers also belongs to the same family of structures. © 2011 Mineralogical Society.},

abstract = {Chromium and vanadium-bearing metamorphic derivatives of siliceous-carbonate sediments in the Sludyanka granulite-facies complex, southern Baikal, contain high-Cr clinopyroxenes that belong to the diopside-kosmochlor-natalyite join (CaMgSi2O6-NaCrSi2O6-NaVSi2O6). The ternary join includes isomorphic binary joins of which the diopside-kosmochlor join with 94% kosmochlor (Kos) end-member has been studied in detail and found to be virtually complete. As indicated by signature of diopside-eskolaite reactions in the minerals, kosmochlor and high-Cr members of the join formed at the expense of metamorphic eskolaite as a result of Na input after progressive metamorphism. There is no miscibility gap along the diopside-kosmochlor join; the incompleteness of the kosmochlor formation reaction and the coexistence of its compositionally different members are rather due to kinetic factors associated with low mobility of Cr. Thus, the mechanism of Cr incorporation in clinopyroxenes does not depend on PT-conditions of metamorphism. © 2010.},

abstract = {Elbrusite-(Zr) Ca3(U6+Zr)(Fe6+ 2Fe2+)O12, a new uranian garnet (Ia3d; a ≈ 12.55 Å; V ≈ 1977 Å3; Z = 8), within the complex solid solution elbrusite-kimzeyite-toturite Ca3(U;Zr;Sn;Ti;Sb;Sc;Nb⋯) 2(Fe;Al;Si;Ti)3O12 was discovered in spurrite zones in skarn xenoliths of the Upper Chegem caldera. The empirical formula of holotype elbrusite-(Zr) with 25.14 wt% UO3 is (Ca 3.040Th00.018Y0.001) Σ3.059(U6+0.658Zr1.040Sn 0.230 Hf0.009.Mg0.004)Σ1.941 (Fe3+1.575Fe2+0.559Al 0.539Ti4+0.199Si0.099Sn 0.025V5+0.004)Σ3O12. Associated minerals are spurrite, rondorfite, wadalite, kimzeyite, perovskite, lakargiite, ellestadite-(OH), hillebrandite, afwillite, hydrocalumite, ettringite group minerals, and hydrogrossular. Elbrusite-(Zr) forms grains up to 10-15 μm in size with dominant {110} and minor {211} forms. It often occurs as zones and spots within Fe3+-dominant kimzeyite crystals up to 20-30 μm in size. The mineral is dark-brown to black with a brown streak. The density calculated on the basis of the empirical formula is 4.801 g/cm 3 The following broad bands are observed in the Raman spectra of elbrusite-(Zr): 730, 478, 273, 222, and 135 cm-1. Elbrusite-(Zr) is radioactive and nearly completely metamict. The calculated cumulative dose (α-decay events/mg) of the studied garnets varies from 2.50 × 1014 [is equivalent to 0.04 displacement per atom (dpa)] for uranian kimzeyite (3.36 wt% UO3), up to 2.05 × 1015 (0.40 dpa) for elbrusite-(Zr) with 27.09 wt% UO3.},

abstract = {A new Sn-rich garnet, toturite Ca3Sn2Fe 2SiO12, occurs as an accessory mineral in high-temperature altered carbonate-silicate xenoliths in ignimbrite of the Upper Chegem structure in the Northern Caucasus, Kabardino-Balkaria, Russia. The empirical formula of toturite from the holotype sample is (Ca2.989Fe 2+0.011)Σ3(Sn 4+ 1.463Sb5+0.325Ti4+ 0.193Zr0.013Mg0.003Nb5+ 0.002Cr0.001)Σ2(Fe3+ 1.633Al0.609Si0.552Ti4+ 0.166Fe2+0.039V5+ 0.001)Σ3O12. The mineral forms thin regular growth zones and irregular spots in the Fe3+-dominant analog of kimzeyite. Toturite is cubic, Ia3¬d, a ≈ 12.55 Å, as is confirmed by electron backscatter diffraction (EBSD) data. The strongest lines of the calculated powder diffraction pattern are [d; Å (hkl) I]: 2.562 (422) 100, 1.677 (642) 91, 3.138 (400) 74, 4.437 (220) 67, 1.146 (10.4.2) 31, 1.046 (884) 25, 1.984 (620) 23. Raman spectra of toturite are analogous to those of kimzeyite and shows the following diagnostic bands (cm-1): 244, 301, 494, 497, 575, 734. The association of toturite with larnite, rondorfite, wadalite, magnesioferrite, lakargiite, and cuspidine indicates a high temperature (>800 °C) of formation. The mineral name is given after the Totur River situated in Eltyubyu village, also Totur is the name of a Balkarian god.},

Significant vacancies (29%) occur only on one of the two pseudo-equivalent Z1 sites (Z1b). In addition, the Si-O distance at the Z1b site remarkably increases up to 1.707(3) Å, indicating the existence of a hydrogarnet-like substitution, while Z1a, the other pseudo-equivalent Si site, has only 5% vacancies associated with an Si-O distance of 1.636(3) Å. The total refined Si site occupancy of 17.7 atoms per formula unit is in excellent agreement with the results of electron-microprobe analyses.},

abstract = {The crystal structures of three different solid-solution members between the new mineral oxyvanite (V3O5) - and berdesinskiite (V2TiO5) from a quartzite rock in the Pereval marble quarry of the Sludyanka complex, south of Lake Baikal (Russia), have been refined in space group C2/c (a ≈ 10.0; b ≈ 5.0; c ≈ 7.0 Å; β ≈ 111°) from X-ray single-crystal diffraction-data. The composition of the studied crystals, determined by electron-microprobe analyses, is: (V 1.673+Cr0.333+)(V 0.594+Ti0.414+)O5, (V1.673+Cr0.333+)(V 0.464+Ti0.544+)O5, and (V1.383+Cr0.613+)(V 0.244+Ti0.764+)O5. The common structure type of oxyvanite and berdesinskiite can be described by hexagonal closest oxygen packing with 3/5 of the octahedral voids occupied. Site-occupancy refinements support previous studies on synthetic V 2Ti05 and V305 indicating that a strongly distorted octahedrally coordinated site, forming pairs of face-sharing octahedra, is 1:1 occupied by M3+ and M4+ (Ti 4+; V4+) whereas a more regular octahedral site is only occupied by M3+ (V; Cr).},

abstract = {Batisivite has been found as an accessory mineral in the Cr-V-bearing quartz-diopside metamorphic rocks of the Slyudyanka Complex in the southern Baikal region, Russia. A new mineral was named after the major cations in its ideal formula (Ba; Ti; Si; V). Associated minerals are quartz, Cr-V-bearing diopside and tremolite; calcite; schreyerite; berdesinskiite; ankangite; V-bearing titanite; minerals of the chromite-coulsonite, eskolaite-karelianite, dravite-vanadiumdravite, and chernykhite-roscoelite series; uraninite; Cr-bearing goldmanite; albite; barite; zircon; and unnamed U-Ti-V-Cr phases. Batisivite occurs as anhedral grains up to 0.15-0.20 mm in size, without visible cleavage and parting. The new mineral is brittle, with conchoidal fracture. Observed by the naked eye, the mineral is black and opaque, with a black streak and resinous luster. Batisivite is white in reflected light. The microhardness (VHN) is 1220-1470 kg/mm2 (load is 30 g), the mean value is 1330 kg/mm2. The Mohs hardness is near 7. The calculated density is 4.62 g/cm3. The new mineral is weakly anisotropic and bireflected. The measured values of reflectance are as follows (λ; nm - R′max/R′min): 440-17.5/17.0; 460-17.3/16.7; 480-17.1/16.5; 500-17.2/16.6; 520-17.3/16.7; 540-17.4/16.8; 560-17.5/16.8; 580-17.6/16.9; 600-17.7/17.1; 620-17.7/17.1; 640-17.8/17.1; 660-17.9/17.2; 680-18.0/17.3; 700-18.1/17.4.

Lakargiite forms pseudo-cubic crystals up to 30-35 μm in size and aggregates up to 200 μm. Lakargiite is associated with spurrite, larnite, calcio-olivine, calcite, cuspidine, rondorfite, reinhardbraunsite, wadalite, perovskite, and minerals of the ellestadite group. The new perovskite mineral belongs to the ternary solid solution CaZrO3-CaTiO3- CaSnO3 with a maximum CaZrO3 content of ca. 93%, maximum CaTiO3 content of 22%, and maximum CaSnO3 content of 20%. Significant impurities are Sc, Cr, Fe, Ce, La, Hf, Nb, U, and Th. Raman spectra of lakargiite are similar to those of the synthetic phase Ca(ZrTi)O3 with strong bands at 352, 437, 446, 554, and 748 cm-1. Lakargiite crystallized under sanidinite-facies conditions of contact metamorphism characterized by very high temperatures and low pressures.},

The modular structure of dovyrenite is build by alternate stacking of Ca-polyhedral layers characteristic of the tobermorite structure and octahedral layers with attached disilicate groups known from the rosenbuschite group of minerals. No indications of ordered polytypes were detected for the potential OD-structure. Either the small crystal size producing only weak diffraction intensities did not allow detecting diffuse diffraction features (or "super-structure" reflections) or the structure is build by disordered stacks of OD layers. Nevertheless, the resolved average structure allowed unraveling the possible order patterns within the rosenbuschite-like octahedral layers. The key for understanding the polytypic character of this structure is the short periodicity of the tobermorite-like Ca polyhedral layer of only 3.73 Å along c, whereas the periodicity of the attached rosenbuschite-like octahedral layer is doubled. In dovyrenite Ca occurs in sixfold-, sevenfold-, and eightfold-coordination. The octahedral Ca site is only half occupied and may reveal additional vacancies, which must be charge balanced by disordered OH-groups replacing O. A corresponding modular structure with the same subunits but different composition and without octahedral vacancies exists for rinkite (Ti;Nb;Al;Zr)(Na; Ca)3(Ca; Ce)4[Si2O7]2 (O;F)4, which has hitherto been considered as heterophyllosilicate.},

Vesuvianite contains two structural types of OH groups. There are four to six bands in its vibration spectra that are explained as due to different coordination effects. In this paper, the results of Raman investigations on the OH region in vesuvianite are given for the first time. Investigations on ferrous vesuvianite in rodingites from the Urals show that analogous modes are active on both FTIR and Raman spectra. Using a sample of super-clear vesuvianite with P4/n symmetry and ordered structure [a = 15.523(1) Å; c = 11.810(1) Å; P4/n; R1 = 0.0343] from Kazakhstan, it is demonstrated that the character and position of OH bands on vibration spectra are connected not only with coordination effects but also with statistically disordered proton sites and with the number and character of hydrogen bonds. The true symmetry of the vesuvianite from Kazakhstan is lower than P4/n as determined on the basis of the X-ray single-crystal diffraction data. © 2006 Elsevier B.V. All rights reserved.},

The Mössbauer spectra show a gradual decrease of quadrupole splitting and line width values of an Fe 3+ doublet with increasing annealing temperature. Rather unexpected feature of these spectra for an Fe2+ doublet is a considerable increase of the line width with progressive crystallinity and a simultaneous decrease of both quadrupole splitting and isomer shift values. Changes of the hyperfine parameters as a function of the annealing temperature appeared as sensitive indicators of the thermal recrystallization process of metamict davidite similar to metamict silicates.},

Electron-microprobe analyses indicate that this vesuvianite has only ca. 16 Si pfu in contrast to regular vesuvianite with 18 Si pfu. Site-occupancy refinement yielded substantial vacancies at orthosilicate sites Z(1): 25% vacancies, Z(2): 16% vacancies. Vacancies at the tetrahedral site are associated with increased Z(1)-0 and Z(2)-O distances, 1.687 and 1.660 Å, respectively. Vacancies and increased Z(1)-O and Z(2)-O bond lengths are consistent with hydrogarnet-type defects, where SiO4 is replaced by H4O4 tetrahedra. The single crystal investigated shows the highest hydrogarnet-type substitution analyzed by structure refinement of vesuvianite. No vacancies were found involving the disilicate groups. Along the e axis, the increased size of Z(1) tetrahedra is balanced by a compression of the adjacent X(3) Ca-bearing dodecahedra. This structural flexibility is the reason why the length of the c axis remains largely independent of the hydrogarnet-type substitution. A corresponding structural flexibility does not exist along the a axis, leading to a systematic increase of a with increasing proportion of vacancies at the Si site. Polarized Raman spectra in the OH-stretching region are interpreted to indicate that hydrogarnet-type defects in vesuvianite lead to a more isotropic polarization of the absorption bands at about 3650 cm-1.},

abstract = {Atoll garnets in aposkarn serpentinite from the Wiluy River, Republic of Sakha-Yakutia, Russia, have the classic form comprising a garnet core, an intermediate zone filled with chlorite-group minerals and an outer garnet atoll. The core of an illustrated example is complexly zoned from schorlomite to grossular-andradite. Morphologically, the core is a rhombic dodecahedral crystal. The atoll crystallized as a tetragon-trisoctahedron with minor rhombic dodecahedron faces and is composed of hibschite and "hydroandradite". The atoll garnet formed as the result of selective dissolution and substitution by chlorite of an internal hibschite zone with columnar structure that became unstable under new conditions of crystallization. The pattern of dissolution traces defects in the garnet crystal. The growth of the atoll garnets reflects the main stages in the evolution of the Wiluy deposit itself and is associated with the development of the Siberian traps.},

In presented work the oxide ceramic materials in the Na2O-CaO-Al2O3-P2 O5-SiO2 system were obtained. The materials in the glass, glass-ceramics and crystalline form were studied. With IR and Raman spectroscopy the phase composition of these materials was found. With vibrational spectroscopy methods the glassy or crystalline state can be recognized. The short-range structural order of the glass phase was determined also. The most interesting results concern the glass-ceramics materials whose chemical and phase composition indicates its potential biological activity and good enough mechanical properties. © 2003 Elsevier Science B.V.

abstract = {Structural studies of the NaCaPO4-SiO2 materials have been carried out. Amorphous materials from this system, after controlled crystallization process, can be used as potential nanomaterials. Structural studies of nanomaterials are of fundamental importance in view their future applications. Materials of different [PO4]3-/[SiO4]4- tetrahedra proportion have been prepared. Na+ and Ca2+ cations have compensated the negative charge of the lattice. Amorphous and crystalline materials have been obtained by sol - gel as well as conventional melting methods. The XRD phase identification has enabled amorphous and crystalline materials identification and suggests the separation of phosphorus and silicate crystalline phases. The obtained materials were examined using the electron scanning microscope and EDX spectrometer. Analysis of electron scanning microscope maps shows considerable inhomogeneity of crystalline samples. Fluctuations in ions distribution, in case of amorphous materials, have been noted too. DTA investigations have enabled to find the probable characteristic temperatures of glass crystallization. Detailed infrared spectroscopy measurements have been carried out. The spectra of obtained materials have been compared with the spectra of cristobalite. Spectroscopic studies confirm the inhomogeneity of materials. © 2003 Elsevier Science B.V.

abstract = {A low-temperature, Si-deficient variety of vesuvianite occurs in porous tetrahedral "achtarandite" pseudomorphs consisting of hibschite, along the banks of the Wiluy River, Yakutia, Russia, the type locality of grossular and wiluite. The (H4O4 4--for-(SiO4)4- hydrogarnet-type substitution is evident in the vesuvianite; a substitution that allows it to be considered an analogue of hibschite. This variety of vesuvianite belongs to a new series in the vesuvianite group; as expressed by the formula X19Y13T0-5(Si2O7 4(SiO4)10-x(OH)4x W10. The filling of the X; Y; and T positions in this Si-deficient vesuvianite; where x varies from 0.67 to 2.89; is analogous to that in vesuvianite and wiluite. The Si-deficient vesuvianite is characterized by increased unit-cell parameters; a 15.688(3); c 11.860(3 Å and by lower indices of refraction; ε 1.691(1); ω 1.668(1). In the OH-region; the FTIR and Raman spectra differ sharply from those of low-temperature vesuvianite from rodingites; but are similar to the spectra of hibschite. A line near 3620 cm-1 indicates that the substitution occurs only in the isolated tetrahedra. More than 25% of these can be substituted by (H4O4 ). Contents of boron up to 2.48 apfu were detected in the Si-deficient vesuvianite. The vesuvianite formed during the hydration (serpentinization and rodingitization) of early; high-temperature skarns.},

abstract = {Whiskers and needles of F-rich vesuvianite were found together with diopside in cavities of an altered magnesian skarn in the Tas-Khayakhtakh Mountains of Polar Yakutia, in Russia. The acicular crystals are strongly zoned and formed between two generations of diopside. The chemical composition of the vesuvianite whiskers is more homogeneous and resembles that of the outermost rim of the vesuvianite needles. In the last stage, fluorapophyllite, prehnite, titanite, calcite and quartz overgrew vesuvianite. Whiskers of vesuvianite crystallized at low activity of CO2 and P-T conditions corresponding to the prehnite-pumpellyite facies. Single-crystal X-ray refinements of the structure of three vesuvianite whiskers, for which electron-microprobe data also were collected, revealed P4/nnc space-group symmetry and (F;Cl) substitution at O(10) within disordered strings running parallel to the four-fold axis. In addition, there is partial substitution of F at O(11), usually occupied by OH in low-temperature vesuvianite. The high symmetry (P4/nnc) in low-temperature (<350°C) whiskers at vesuvianite adds evidence that the degree of string order is determined not only by the temperature of crystallization, as hitherto assumed, but also by the prevailing composition of the fluid and the regime of crystal growth leading to substitutions that disturb intra-rod order and particularly long-range rod order. Long-range rod order leads to reduced symmetry (P4/n or P4nc), typical of vesuvianite crystallized at low temperature in rodingites. Vesuvianite whiskers formed in a kinetic regime where the growth rates were selectively influenced by surface-active substances poisoning the prism faces. Growth of faces in vesuvianite whiskers is explained by a tangential layer-by-layer mechanism without participation of a central screw dislocation.},

abstract = {Achtarandite, tetrahedral pseudomorph after a wadalite-like mineral, is represented by different types of pseudomorphs on the Wiluy deposit. As a result of processes and mechanisms of pseudomorphic substitution of wadalite (protoachtarandite) by hydrogarnet are white, predominantly hibschite pseudomorphs. Crystal chemical affinity of the protophase (wadalite) and metaphase (hibschite) and morphological particularities of achtarandite allowed to classify these pseudomorphs as the sponge pseudomorphs formed in the systems with isomorphic components. Peculiarities of the internal morphology, character of morphology and composition evolution of hydrogarnet from achtarandite pseudomorphs: {111} hibschite → {110} Fehibschite → {211} Ti-hydroandradite (GALUSKINA et al. 2001), allowed to distinguish successive formation stages of the sponge pseudomorphs and to determine mechanisms of structure formation corresponding to these stages. Sponge structure of pseudomorphs was forced by the substitution mechanisms (mechanisms of the simultaneous growth and dissolution) at the conditions of volume deficit of new-formed phase.},

abstract = {Hibschite is a widespread mineral in the Wiluy deposit of achtarandite. It is the main rock forming mineral in the rodingite-like rock, and it usually concentrates in achtarandite pseudomorphs within the serpentinite and chlorite layers. In the presented paper morphology and composition study of hydrogarnets from white sponge achtarandite pseudomorphs, being in the epitaxial growths with grossular crystals is presented. Morphological features and chemical composition of hydrogarnet are connected with the stages of achtarandite pseudomorphs formation. The main evolution trend of the form and the composition of hydrogarnet were established: {111} hibschite → {110} Fe-hibschite → {211} Ti-hydrograndite. The {111} form of hibschite reflects the non-equilibrium conditions of crystallisation at the early stage of achtarandite sponge pseudomorph formation, its appearance was connected with stabilising effect of surface-active substance. The non-equilibrium character of the octahedron determined features of its replacement by {110} faces with formation of skeletal and translation forms. Replacement of {110} by {211} was performed gradually at the expense of dying-out of quickly growing {110} faces on the background of increase of post-magmatic solutions acidity, which determined the increase of Fe content in hydrogarnet and changed the growth mechanism of its faces.},

abstract = {In this work IR spectra of synthetic and natural ring silicates (cyclosilicates) containing in their structure isolated silicooxygen rings of various numbers of members (n = 3; 4; 6) have been presented. By means of factor group analysis it has been shown that only one intensive band characteristic of ring structures ("ring band") should be observed in the IR spectra of cyclosilicates. The ring band position is related to the number of ring members [M. Handke; M. Sitarz; W. Mozgawa; J. Mol. Struct. 450 (1998) 229] and strongly depends on the kind of non-ring cations connecting the rings. The existence of the cations such as Ti4+, Zr4+, Cu2+ etc. in the cyclosilicates structure causes the conjugation of the vibrations, making the interpretation of the spectra more difficult. In this work we have shown that the presence of such non-ring cations causes the shifting of the "ring band" to the higher wavenumbers. In the case when Al3+ are non-ring cations it is almost impossible to identify the "ring band" (6-membered cyclosilicates). © 2000 Elsevier Science B.V.},

Core, intermediate zone and ring (atoll) are the structural components of the atoll hydrogarnets. Core and internal zone of the ring are hydrogrossulars with compositions of Grs80Adr20 and Grs74Adr24Pyr2, respectively. External zone of the ring is hydroandradite (Adr58Grs37Pyr5). Atoll hydrogarnets are involved in pole-like formations and curved plates, which are elements of the hydrogarnet skeleton of achtarandite pseudomorphs. They formed as a result of the epitaxial replacement of protoachtarandite (wadalite) by hydrogarnet. Model of the atoll hydrogarnet growth is proposed, which explains a mechanism of the formation of achtarandite pseudomorphs.},

The aragonite twins by 2′ mm′ possess dipyramidal habit untypical for aragonite with the developed [121] faces and re-entrant corner formed by [hk0] faces. The 27 simple forms were determinated on the crystals with goniometry, 15 of them were established for aragonite first. The new simple forms, usually with irrational indices, take part in facing of the re-entrant corner and "re-exitant" corner on the aragonite twins. Anatomy of the aragonite twins exposed by luminescence and X-ray topography indicates realization of re-entrant corner effect during their growth. Manifestation of the re-entrant corner effect was connected with influence of impurities, playing a significant role at low temperatures, which on the one hand stabilize growth of the faces with the high indices, but on the other hand accelerate one-sided growing of the crystal in area of the re-entrant corner.},
