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.

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.

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.

On the basis of the crystal-chemical arguments and heterovalent isomorphic substitution scheme M++T6+ ↔ M2++T5+, the palmierite supergroup can be formally divided into two groups: the palmierite group M12+M22+(T6+O4)2, and the tuite group M12+M222+(T5+O4)2. Currently, the palmierite group includes palmierite K2Pb(SO4)2, and kalistrontite K2Sr(SO4)2, whereas the tuite group combines tuite Ca3(PO4)2, mazorite Ba3(PO4)2, and gurimite Ba3(VO4)2. The isostructural supergroup members crystallise in space group R̅3m (no. 166). The palmierite-type crystal structure is characterised by a sheet arrangement composed of layers formed by M1O12 and M2O10 polyhedra separated by TO4 tetrahedra perpendicular to the c axis. The abundance of distinct ions, which may be hosted at the M and T sites (M = K; Na; Ca; Sr; Ba; Sr; Pb; Rb; Zn; Tl; Cs; Bi; NH4 and REE; T = Si; P; V; As; S; Se; Mo; Cr and W) implies many possible combinations, resulting in potentially new mineral species.

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 = {Gismondine-Sr, recently discovered in the Hatrurim Complex in Israel, has been recognised in a xenolith sample from the Bellerberg volcano in Germany. The empirical crystal-chemical formula indicates elevated K content: (Sr1.74Ca1.05Ba0.09K1.56Na0.49)Σ4.93[Al7.98Si8.06O32]·9.62H2O. Additionally, Ba-rich gismondine and amicite have been found in the low-temperature mineral association of the pyrometamorphic rock from the Hatrurim Complex. The Raman spectra of the studied zeolites and the crystal structure of gismondine-Sr from the second occurrence are presented. A review of zeolites with GIS framework-type structure leads to the following conclusions: (1) garronite-Na and gobbinsite are equivalent and constitute a solid solution with garronite-Ca; (2) gismondine-Ca, -Sr, and amicite belong to one mineral series; (3) two zeolites series with different R-factors (defined as Si/(Si+Al+Fe)) can be distinguished within GIS topology: the garronite series (R > 0.6) including garronite-Ca and gobbinsite, with general formula (MyD0.5(x-y))[AlxSi(16-x)O32]·nH2O, where M and D refer to monovalent and divalent cations, respectively; and the gismondine series, including amicite, gismondine-Sr and gismondine-Ca, with R ≈ 0.5, and the general formula (MyD0.5(8-y))[Al8Si8O32]·nH2O. The Raman band between 475 cm-1 and 485 cm-1 is distinctive for the garronite series, whereas the band around 460 cm-1 is characteristic of the gismondine series. On the basis of these findings, a revision of GIS zeolites nomenclature is suggested. Copyright © The Author(s), 2023.

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.

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.},

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.

This is the second reported occurrence of flörkeite previously found in a Ca-rich xenolith from a quarry at the Bellerberg volcano near Ettringen, East Eifel volcanic area, Germany. 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 = {The Hatrurim Basin, Israel, is located on the western border of the Dead Sea Transform. This is one of the localities of a unique pyrometamorphic complex whose genesis remains problem-atic. This paper deals with zeolite‐bearing rock that is known in the Hatrurim Basin only. The strata subjected to zeolitization is called the “olive unit” and consists of anorthite–pyroxene (diopside– esseneite) hornfels. Zeolitization occurred in an alkaline environment provided by the interaction of meteoric water with Portland‐cement‐like rocks of the Hatrurim Complex. The resulting zeolite-bearing rocks contain 20–30% zeolitic material. The main zeolitic minerals are calcic: thomsonite‐Ca ± Sr, phillipsite‐Ca, gismondine‐Ca, and clinoptilolite‐Ca. The remainder is calcite, diopsidic pyrox-ene, garnets (either Ti‐andradite and/or hydrogrossular), and less frequently, fluorapatite, opal, and others. Their major mineralogical and chemical compositions resemble carbonated zeolite‐blended Portland mortar. Rocks show different values of porosity. Their mechanical characteristics are much better for samples with porosity values below 24%. The related parameters are like those of blended concretes. The minimal age of zeolitization is 5 Ka. The natural zeolite‐bearing rocks are resistant to weathering in the Levant desert climate. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.},

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.

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.

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.},

abstract = {Until now, only the colourless crystals of mineral afwillite, Ca3(HSiO4)2·2H2O, were known from several localities around the world. Present work focuses on blue afwillite counterparts from the Ma'ale Adummim locality in Palestine. Using the wide spectrum of analytical methods we attempted to identify the causes of this unusual colour. Structural investigation confirms the presence of two tetrahedral SiO3OH units connected by hydrogen bonds. The Raman spectrum of afwillite, obtained for the first time, shows the increased number of bands in the range of 785-970 cm-1, whose assignation was correlated with the presence of two different kinds of structural units: (SiO3OH)3- and its deprotonated counterpart (SiO4)4-. The heating process at 250 °C, in addition to the colour changes from blue to pastel green, shows the intensity reduction and disappearing of some Raman bands attributed mainly to SiO3OH units. The IR investigation confirms also the presence of that unit and provides information that the position and designation of infrared bands above ∼2300 cm-1 is related to the strength of hydrogen bonds within the structure. The stretching and bending OH vibrations of afwillite sample show the partial shift to the lower spectral frequencies after the H/D isotopic exchange in OH or H2O groups. Based on the results of the electron absorption and luminescence analyses it has been proposed that the blue colour of afwillite is caused by hole oxygen defect, most probably SiO3 -. © 2019 The Authors},

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.

abstract = {A number of the baryte, BaSO4, - hashemite, BaCrO4, solid solution compounds were synthesized previously. In this study, Raman spectra of naturally occurring phases belonging to the baryte-hashemite series from the pyrometamorphic rocks of the Hatrurim Complex were investigated. The Raman spectrum of natural hashemite, obtained for the first time, shows the position of the fundamental bands for the chromate anion vibrations. The bands related to the stretching vibrations (ν1; ν3) occur at 864 cm−1 and in 871–909 cm−1 regions, whereas the bending vibrations (ν2; ν4) are visible in the 346–360 cm−1 and 400–422 cm−1 range, respectively. Received results allowed to observe a gradual shift of bands in baryte-hashemite solid solution as a consequence of the substitution by different cations. The position of bands depends on the Cr/S ratio in analysed samples, and it is determined by differences in atomic mass, and ionic radii between Cr6+ and S6+, which affect changes in the strength and length of bonds. The occupancy of the same atomic position by two different cations enables to notice variations of polyhedra geometry, and unit cell parameters despite that baryte and hashemite are isostructural and crystallize in the same Pnma space group. We also confirm that the immobilization of the toxic (CrO4)2− ion in the baryte structure may occur directly without oxygen state reduction, we propose to using a baryte-hashemite solid solution as a reservoir for the incorporation of Cr as an environmental pollutant. © 2018 Elsevier B.V.},

abstract = {The mayenite group includes minerals with common formula Ca12Al14O32−x(OH)3x[W6−3x], where W = F, Cl, OH, H2O and x = 0–2. This distinction in the composition is associated with W site which may remain unoccupied or be occupied by negatively charged ions: OH−, F−, Cl−, as well as neutral molecules like H2O. However, there is no experimental approach to easily detect or differentiate mineral species within the mayenite group. Electron micro-beam facilities with energy- or wavelength-dispersive X-ray detectors, as most common tools in mineralogy, appear to be insufficient and do not provide a definite identification, especially, of hydroxylated or hydrated phases. Some solution provides typical Raman analysis ensuring identification of minerals and 3D Raman imaging as an innovative approach to distinguish various co-existing minerals of the mayenite group within a small area of the rock sample. Raman spectroscopy has also been successfully used for a determination of water type incorporated into the mineral structure as well as for a spatial distribution of phases by cluster approach analysis and/or integrated intensity analysis of bands in the hydroxyl region. In this study, Raman technique was for the first time used to reconstruct a 3D model of mayenite group mineral zonation, as well as to determine a way of water incorporation in the structure of these minerals. Moreover, for the first time, Raman data were correlated with alterations during the mineral-forming processes and used for reconstruction of the thermal history of studied rock. As a result, the influence of combustion gases has been proposed as a crucial factor responsible for the transformation between fluormayenite and fluorkyuygenite. © 2018, The Author(s).},

abstract = {Katoite-bearing rock was revealed in the Hatrurim Basin, Israel. The rock formed by hydration of pyrometamorphic calc-silicate assemblages at temperatures higher than 200 °C. The likely age of the hydration process is Miocene, about 6.2 Ma. The main phases of katoite-bearing rock are minerals of the katoite-grossular series, calcium hydrosilicates, fluorapatite and carbonate. Chemistry and mineralogy of katoite-bearing rock resembles belite sulfoaluminate concrete. Studied samples show two sets of porosities, which are low and high, between 22 and 28% and between 29 and 39%, respectively. Increased porosity characterizes non-weathered katoite-bearing samples, whereas decreased porosity is linked to carbonation during weathering. Katoite remained stable in spite of natural alkaline leaching. Although high porosity samples display decreasing strength parameters, most observed rock mechanic characteristics are comparable to modern-day concrete. We suggest that obtained data on natural katoite-bearing rock can simulate the longevity and durability of belite sulfoaluminate concrete. © 2018 Elsevier Ltd},

The mineral was discovered in spurrite rocks of the Hatrurim Complex in the Negev Desert near Arad, Israel. Associated minerals are spurrite, calcite, brownmillerite, shulamitite, CO3-bearing fluorapatite, fluormayenite-fluorkyuygenite, and ariegilatite. The empirical formula of stracherite is: (Ba0.96K0.02Na0.01)S0.99Ca6.01[(SiO4)1.86 (PO4)0.12(AlO4)0.01(TiO4)0.01]S2[(PO4)1.05(CO3)0.75(SO4)0.18(VO4)0.02]S2(F0.95O0.03)S0.98. Poikilitic crystals of stracherite are up to 0.5 mm in size and are confined to re-crystallization zones of spurrite marbles under the influence of by-products (gases; fluids) of combustion metamorphism.. © 2018 Walter de Gruyter GmbH, Berlin/Boston.},

The crystals are up to 0.3 mm × 0.1 mm in size and form intergrowths with hematite, magnesioferrite, khesinite, and harmunite. 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.

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.

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.

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 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.

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).},

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.

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.

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.},

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.},

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.

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.

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.

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.

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).},

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.},

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.

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 = {Postsedimentation alteration and structural assemblies of the Triassic sedimentary complexes of West Chukotka are discussed. Zoning of the alteration is based on examination of newly formed structural and mineral assemblages, the chemical composition, and the polytypes of clay minerals. Three zones of postsedimentation transformation of sandstones are distinguished: (1) the zone of chlorite, illite, and mixed-layer disordered chlorite-smectite; (2) the zone of illite and chlorite; and (3) the zone of phengite and ferroan chlorite. The grade of postsedimentation transformation and the composition of the newly formed micas are correlated with the cleavage type. The development of two-three types of cleavage leads to the highest degree of rock transformation. The assemblages of clay minerals and the crystal chemistry of the authigenic phengite show that the grade of postsedimentation transformation of the Triassic rocks attains the stage of greenschistfacies metamorphism in the zone of development of two cleavage types. Where the second cleavage is not documented or poorly developed, the rocks remain unmetamorphosed. Evidence is given that postsedimentation transformation of terrigenous rocks in the foldbelt is controlled largely by deformation. © 2011 Pleiades Publishing, Ltd.},

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.},

abstract = {This paper presents the results of structural, lithologic, and geochronological (K-Ar; Rb-Sr) studies of the Carnian terrigenous rocks in the sedimentary cover of the Chukchi microcontinent and U-Pb dating of detrital zircons. From the lithological features, three types of sections are recognized. Terrigenous sequences of the first type were deposited on the outer shelf in the distal zone of the prograding delta, sequences of the second type accumulated at the rise of continental slope, and sediments of the third type are characteristic of the pelagic zone. In mineralogy and geochemistry, sandstones are rather uniform and inherit the sialic composition of provenance. The detrital zircons comprise several populations with predominance of the varieties derived from igneous rocks. The U-Pb age of the youngest population is 236-255 Ma. The conditions of postsedimentation alteration reached those of greenschist metamorphic facies and anchimetamorphism. Several cleavage systems have been established. Sericite related to the oldest system is distinguished by elevated Ti, Mn, and Fe components. The first stage of deformation of the Carnian sedimentary rocks about 200 Ma ago resulted in the rearrangement of K-Ar and Rb-Sr isotopic systems in whole-rock samples and minerals and is clearly recorded in isotopic data. It is suggested that the deformation related to the normal faulting in Triassic rocks and the emergence of the Lesser Anyui Block were plausible causes of the first structural rearrangement. © Pleiades Publishing, Inc. 2007.},

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.},

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.},

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 = {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 = {The atoll hydrogarnets have been observed in achtarandite pseudomorphs from the Wiluy deposit in Yakutia, Russia. Atoll structure in hydrogarnets is described for the first time. 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.},

abstract = {The morphological and X-ray structural investigations of the aragonite twins from Faustianka (Poland) revealed two laws of twinning with the 2′/m and 2′ mm′ point symmetries and the (110) twin plane. 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.},
