abstract = {The mineral composition and tube ultrastructure of the Middle and Upper Jurassic cal-careous sabellid Glomerula gordialis (Schlotheim; 1820) from the Polish Basin have been assessed. In all cases, the Jurassic sabellid tubes studied were found to consist of low-Mg calcite, as revealed by Raman spectroscopy and supplementary SEM-EDS analyses. The tube of Glomerula gordialis is single-layered and its ultrastructure has been identified as a spherulitic prismatic structure (oriented prismatic structure), supporting earlier ultra-structural observations of calcareous sabellids. The ambient seawater chemistry largely influenced the formation and evolution of sabellid skeletal mineralogy, and their mineral composition at the times of their first appearance presumably corresponded to the Permian aragonitic seas. The earliest skeletons of each calcareous polychaete group are considered to have autonomously evolved according to the chemistry of the seawater at the time of their origin. The relatively simple biomineralization system of sabellids is similar to that of calcareous cirratulids and remains less complex compared to serpulids. Physiologically less expensive formation of the calcareous tube in sabellids implies their palaeoecological avoidance strategy, allowing for a faster dispersal over the substrate during potentially unfavourable conditions. © 2023 Author(s).},

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 = {Raman microspectroscopy and thermo‐optical‐transmittance (TOT) method were used to study airborne ambient soot collected at the suburban air monitoring station in southern Poland during the residential heating (January‐February) and non‐heating (June–July) seasons of 2017. Carbonaceous material constituted on average 47.2 wt.% of PM2.5 during the heating season and 26.9 wt.% in the non‐heating season. Average concentrations of OC (37.5 ± 11.0 μg/m3) and EC (5.3 ± 1.1 μg/m3) during the heating season were significantly higher than those in the non‐heating season (OC = 2.65 ± 0.78 μg/m3; and EC = 0.39 ± 0.18 μg/m3). OC was a chief contributor to the TC mass concentration regardless of the season. All Raman parameters indicated coal combustion and bio-mass burning were the predominant sources of soot in the heating season. Diesel soot, which is structurally less ordered than soot from other sources, was dominant during the non‐heating season. The D1 and G bands area ratio (D1A/GA) was the most sensitive Raman parameter that discriminated between various soot sources, with D1A/GA > 1 for diesel soot, and less than 1 for soot from coal and wood burning. Due to high daily variability of both TOT and Raman spectroscopy data, single‐day measurements can be inconclusive regarding the soot source apportionment. Long‐time measurement campaigns are recommended. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {The chalcocite group minerals are widely distributed among different hydrothermally affected rocks, the oxidized zone of copper sulfide deposits, or may be even crystalline from supersat-urated volcanic gases. Some of the chalcocite group minerals form the main Cu orebodies. Djurleite (Cu31S16) is a rare member of the chalcocite group, with a very complex structure. The physical and chemical similarities between all members of the group make them almost unidentifiable by macroscopic and microscopic methods. In this study, Ag-bearing djurleite from the Kupferschiefer deposits, Lower Silesia, Poland, is characterized by EMPA (Electron Microprobe Analyses), XRD (X-Ray Diffraction), and Raman spectroscopy. Djurleite from the investigated site has the following general, average chemical formula: Cu30.86Ag0.1Fe0.04S16. The Ag content is up to 0.55 wt.%, while Fe is up to 0.19 wt.%. The presence of djurleite confirms a low-temperature (~90◦C), hydrothermal origin of the Cu-Ag deposit in Kupferschiefer, which is consistent with previously studies. Moreover, the authors believe that Ag-rich djurleite may often be mistaken for Ag-rich chalcocite, which used to be one of the main Ag-bearing minerals in the orebody from the Cu-Ag deposit in the Fore-Sudetic Monocline. However, the confirmation of such a statement requires more samples, which should be studied in detail. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {Zinc and lead smelting slags from Ruda Śląska are unique in their chemistry and phase composition, which resemble rare natural rocks such as paralavas and melilitolites. Moreover, considering its size, we can treat a pyrometallurgical slag dump as a geological body. In slags from Ruda Śląska the assemblage melilite ± pseudowollastonite ± wollastonite ± plagioclase was discovered in glassy slag. High-temperature experiments were performed to determine the temperature conditions and to reconstruct the crystallization of such an assemblage. Two slag samples were subjected to complete melting and crystallization with controlled thermal gradients of: 53.25 °C/h, 15.20 °C/h and 7.60 °C/h. The results showed that crystal nucleation started at temperatures of 1250-1300 °C depending on the fluctuations of chemical composition. In both samples the thermal gradient only partly influenced the phase differentiation, being rather responsible for the disappearance of the primary glass. Moreover, even slight differences in chemical composition resulted in changes in phase assemblages under the same temperature conditions (mll + gls vs pwol+pl + mll + gls). It was proven that it is due to the combination of undercooling conditions and solidus dependences in the åkermanite – gehlenite solid solution. The occurrence of such phenomena should be considered in natural rocks with similar composition. In the case of the Ruda Śląska slags it explains the dominance of glassy slag in that location. The experiments gave us an opportunity to observe and precisely analyze crystallization in real time, providing new insights into the creation of slags and their natural analogues. However, the study has also shown that possible variations of the original crystallization should always be assessed. © 2020 Elsevier B.V.},

abstract = {Southeastern Bulgaria is composed of a variety of rocks from pre‐Variscan (ca. 0.3 Ga) to pre‐Alpine sensu lato (ca. 0.15 Ga) time. The Sakar Unit in this region comprises a series of granitoids and gneisses formed or metamorphosed during these events. It is cut by a series of post‐Variscan hydrothermal veins, yet lacks pervasive Alpine deformation. It thus represents a key unit for detecting potential tectonism associated with the enigmatic Cimmerian Orogenic episode, but limited geochronology has been undertaken on this unit. Here we report age constraints on hydrothermal activity in the Sakar Pluton. The investigated veins contain mainly albite–actinolite– chlorite–apatite–titanite–quartz–tourmaline–epidote and accessory minerals. The most common accessory minerals are rutile and molybdenite. Apatite and titanite from the same vein were dated by U–Pb LA–ICP‐MS geochronology. These dates are interpreted as crystallization ages and are 149 ± 7 Ma on apatite and 114 ± 1 Ma on titanite, respectively. These crystallization ages are the first to document two stages of hydrothermal activity during the late Jurassic to early Cretaceous, using U– Pb geochronology, and its association with the Cimmerian orogenesis. The Cimmerian tectonothermal episode is well‐documented further to the east in the Eastern Strandja Massif granitoids. However, these are the first documented ages from the western parts of the Strandja Massif, in the Sakar Unit. These ages also temporally overlap with previously published Ar–Ar and K–Ar cooling ages, and firmly establish that the Cimmerian orogeny in the studied area included both tectonic and hydrothermal activity. Such hydrothermal activity likely accounted for the intense albitization found in the Sakar Unit. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {Raman spectroscopy was used as a supplementary method to characterise the thermal maturity of Ediacaran organic matter (OM) from the East European Craton. Because this method is based on organic particles measurement, it appears to be a good supplementary method in addition to the acquisition of biomarker data, which is based on extractable organic matter and may be affected by potential contamination. Raman spectroscopy seems to be particularly useful for lower Palaeozoic rocks, which do not contain vitrinite. Here, we compared C31 22S/(S + R) homohopane ratio results (obtained using gas chromatography – mass spectrometry), with various Raman parameters including: G_STA, Gmax position, Dmax/Gmax, FWHMG, RAR, D_STA, and PDmax. Close correlations were observed between C31 22S/(S + R) and G_STA, Gmax position, Dmax/Gmax, and FWHMG, reaching values of R2 = 0.5‒0.6, whereas no correlation existed between homohopane ratio and the RAR, D_STA, and PDmax parameters. Raman spectroscopy results divided Ediacaran samples into two distinctive groups: (i) immature (Russian; Lithuanian; and Belarusian), characterised by relatively higher values of G_STA, Dmax/Gmax, and FWHMG and relatively lower values of PGmax, and (ii) mature (Polish and Ukrainian), with relatively lower values of G_STA, Dmax/Gmax, and FWHMG and relatively higher values of PGmax. Within each group no statistically confirmed differences were found. However, significant discrepancies were observed between the hopane ratio and Raman parameters in Lithuanian samples, in relation to other samples from the group (i). Values of the C31 22S/(S + R) ratio for Lithuanian samples are close to those for the group (ii) and significantly higher than those for the group (i). However, all Raman parameters are the same as those of the rest samples from the group (i), indicating the immature character of OM from Lithuanian rocks. We interpret this discrepancy as representing contamination of the cores with drilling fluids, resulting in increased values for the C31 22S/(S + R) ratio. In this case, Raman spectroscopy is a useful tool for detecting extract contamination and appears to be an effective and decisive method in the case of rocks suspected of contamination. © 2019 Elsevier GmbH},

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 = {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},

abstract = {Small-sized (0.8–1.6 mm in diameter), circular to oval, three-dimensionally preserved calcitized structures have been found embedded within ammonite body chamber moulds from the Lower Aptian (Lower Cretaceous) of Russia. The characteristic morphology, consisting of a flat attachment base and convex upper hemisphere possessing an apical, tiny, circular opening indicate that these structures represent gastropod (possibly Caenogastropoda) egg capsules. Originally, the egg capsules were attached to the empty shells of the ammonites Deshayesites and Sinzovia which later were embedded within carbonate concretions. The preservation of the egg capsules resulted from both their deposition within a suitable, cryptic habitat provided by the empty ammonite shells, and the quick cementation of the infilling sediment which not only sufficiently protected the capsules from external environment, but also created a suitable, closed microenvironment for fossilization. The calcitization of the egg capsules may have occurred under low pH conditions in an environment characterized by a very low concentration of phosphorous ions essential for phosphatization. So far, such structures are known from a few examples derived from different stratigraphic horizons and geographic locations. Those which are known have been reported in the form of pyritized, phosphatized, carbonaceous and even bioimmured fossils. The calcitized gastropod egg capsules presented here indicate, that such structures may in fact be preserved by a wide array of fossilization modes in different paleoenvironments/microenvironments. Thus, such fossils seem to be much more common in the fossil record than previously considered. © 2016 Elsevier B.V.},

abstract = {Rusinovite, Ca10(Si2O7)3Cl 2, was discovered in an altered carbonate-silicate xenolith enclosed in ignimbrites of the Upper Chegem volcanic caldera. The mineral is named after Vladimir Leonidovich Rusinov (1935-2007), a Russian petrologist and expert in the field of thermodynamics of non-equilibriummineral systems. A synthetic analogue of rusinovite is also known. The new mineral has anODstructure of which only the average structure could be determined based on strong and sharp reflections recorded by single-crystal X-ray diffraction: space group Cmcm},
