    Opis:
    Middle Miocene foraminifera from the Skawina Formation of the Upper Silesia Basin have been analysed. The stable oxygen and carbon isotope signatures in Globigerinoides quadrilobatus (shallow pelagic), Globigerina bulloides (deeperpelagic) and Uvigerina spp. (benthic) tests show a temporal pattern of changes in the sections studied. The foraminiferal assemblage biozones of the Badenian that were identified earlier, on the basis of taxonomic composition, correspond to changes in the foraminiferal ẟI8O and ẟI3C values. The CPN7/CPN8 transition - as the Moravian/Wielician border - is marked by distinct isotopic events: a ẟ18O increase (IIAB/IIC boundary) followed by a ẟ13C decrease (IIC/IID boundary).

    Opis:
    The salt deposit in Bochnia is located in the marginal zone of the Carpathian Foredeep. The salt succession, composed of rock salt deposits, with clay stone, mudstone and zuber interbeds was, in its original location, ca. 80 m thick. The carbonized organic material described herein occurs within three salt units: in the southern salts, in the middle salts, and in the northern salts. There are two petrographic forms of coal in the Bochnia rock salt succession: xylite and gelitic coal. Xylites are fragments of fossil wood. Externally, xylite demonstrates a fibrous texture, and can be splintered along the fissility with uneven transverse fractures. The fragments are strongly gelified and show a zonal structure: their internal parts are made of highly cracked textinite, although the external part of the xylite fragments is built of ulminite. The gelitic coal was found in the form of lenticles, formed exclusively of euulminite. Their main mineral components include metasideronatrite (Na242

    Opis:
    Ten new determinations of the stable sulphur isotope content of anhydrite from Badenian rock salt in the Hrynivka 525 borehole (Ukrainian Carpathian Foredeep) show that δ34S values in anhydrite range from +20.2 to +22.7‰ and the average value of δ34S is +21.4 ± 0.3‰. Those values are similar to those of the Neogene marine sulphates. Comparison to other geochemical data (chemical composition of the brine contained in fluid inclusions and the bromine content in halite) suggests that the Badenian Carpathian Foredeep evaporite basin was supplied predominately by seawater solutes where, at different stages of salt accumulation, the influence of continental waters with lighter isotopic compositions of dissolved sulphate was important. The isotopic composition of sulphur (δ 34S) of Badenian seawater, calculated on the basis of sixty analyses of anhydrite related to halite of the Carpathian Region, is approximately +20.3‰, this value being similar to the sulphur isotopic composition of present-day seawater. The δ 34S value for Badenian seawater may have been slightly higher if we consider potential changes of the brine composition of salt-bearing basins caused by inflow of continental waters enriched in light 32S isotopes.

    Opis:
    Analysis of previously available stratigraphic data coupled with the re-interpretation of seismic profiles calibrated by boreholes has allowed the construction of a new tectonic model of evolution of the Gdów “embayment” – a tectonic re-entrant located along the Carpathian front east of Kraków (southern Poland). This model shows that the main phase of localized fault-controlled subsidence took place in the Early Badenian and was associated with deposition of the locally overthickened Skawina Formation. Also, deposition of evaporites of the Wieliczka Formation seems to have been tectonically controlled by local basement faulting. Supra-evaporitic siliciclastic deposits have developed as a result of overall north-directed sediment progradation from the eroded Carpathian belt towards the Carpathian Foredeep. During the final stages of development of the Carpathian fold-and-thrust wedge the previously subsiding Gdów “embayment” area was uplifted and basement faults were reactivated either as reverse faults or as low angle thrust faults. Along the leading edge of this inverted structure a triangle zone developed, with backthrusting along the evaporitic level. As a result, overthickened evaporites, formed in local tectonically-controlled depressions within the area of the Gdów “embayment” area have been strongly folded and internally deformed.

    Opis:
    Taxonomic, quantitative and isotopic study of foraminifera from mudstone and claystone xenoliths incorporated into slump facies of the Stratified Salt Member of the Wieliczka deposit shows that the majority of xenoliths represent the CPN 8 biozone (Wielician substage, Badenian, Middle Miocene). The share of the CPN 7 biozone is minor; it was recorded in two of 26 samples analysed. The source area of xenoliths was the basinal part of the Carpathian Foredeep, located far off the shoreline (shallow-water taxa are not present in the samples); it represents the upper bathyal zone, in oxygenated conditions. Inbenthic, eutrophic and opportunistic foraminifers dominate the benthic environment of the CPN 8 span of time. Increased d18O values of the Globigerina bulloides tests (from +1.7‰ in CPN 7 to +2.3‰ in CPN 8 sediments) was due to the change from the Middle Miocene Climate Optimum to the Middle Miocene Climate Transition at the CPN 7/CPN 8 boundary. This palaeoclimate event is the marker of the Moravian/Wielician chronostratigraphic boundary in the Central Paratethys. The Wielician shows the distinct taxonomic reduction of the Moravian planktonic foraminifera and includes the Globigerina bulloides Acme.

    Opis:
    The most abundant benthic foraminifers recorded in the Wielician salt-enclosed xenoliths are: Bulimina spp., Uvigerina spp., Valvulineria complanata, and Cibicides pseudoungerianus. The predominant taxon in the planktonic assemblage is Globigerina bulloides with a median 98.9% in biozone IIC and 89.1% in the later IID. The IIC assemblage differs from the IID one in both taxon composi tion and abundance. The most pronounced differences are those revealed by Valvulineria complanata counts, number of benfhic taxa and the plankfonic/benthic (P/B) rafio. Pseudotriplasia minuta (one of the Wielician index taxa) occurs only in the IID biozone, present in 16 among 28 samples. There is a noticeable difference in sur- face sculpture morphology pattern in the predominant Bulimina and Uvigerina taxa in the IIC versus the IID biozones. There are smooth (Bulimina elongata) and weakly striate (Uvigerina semiornata plexus) forms in the IIC biozone, foll owed by heavily costate (Bulimina striata) and spinose-pustu l ate (Uvigerina orbignyana plexus) forms in the IID. Globigerina druryi and G. decoraperta- the CPN 8 planktonic index taxa - had not been found in the material studied. Globigerinita uvula is un- usually common in the samples studied. The samples analysed display an abundance of Globigerina bulloides typical of the sub-evaporite Wielician. Hence the studied Wielician stratotype area supports the thesis of the Globigerina bulloides Acme as the valid name designation for the substage.

    Opis:
    The early Badenian interval in the Central Paratethys realm is characterized by a major marine transgression into the Pannonian and Carpathian Foredeep basins. In the western part of the Polish Carpathian Foredeep, Badenian sedimentation started generally with conglomerates (Dębowiec Formation) passing into a thick succession of claystones and mudstones with rare sandstone interbeds (Skawina Formation). Profiles containing a full sequence of lower Badenian strata are relatively rare, and are mainly known from boreholes. In this paper, we present new results on samples taken from such a borehole (Kaczyce K2/07) located near the town of Cieszyn. We focus on reconstructing the chronology of the lower Badenian marine sediments at the beginning of the transgression in the Carpathian Foredeep (lower Skawina Fm.) using radio-isotopic dating (40Ar/39Ar) of a volcanoclastic layer (tuff and tuffite) and biostratigraphy of calcareous nannoplankton and foraminifera.The weighted mean 40Ar/39Ar age for sanidine separates from the tuff provided an age of 14.27 ± 0.03 Ma. This age is consistent with the NN5 and MNN5a nannofossil zones determined in this study. Our foraminiferal assemblages show that the basal beds of the Skawina Formation up to the tuffites correspond to the Orbulina suturalis–Praeorbulina glomerosa Zone (according to Cicha et al., 1975) and cover the interval of the Lower Lagenidae Zone–lowermost Upper Lagenidae Zone (Grill, 1941). The petrographic data from the tuffite allow correlation of the tuffite from the Kaczyce K2/07 borehole to the level of the Chełmek Tuffite Bed (Alexandrowicz, 1997) providing a regional correlation horizon for future studies.

    Opis:
    This study describes a new determination of the S and O isotope composition of Lower Permian (Kungurian) anhydrites from the Upper Pechora Basin, Cis-Ural region, Russia. δ34S values in sulphate facies vary from +13.7 to +15.1‰; and δ18O values range from +9.3 to +10.4‰. The values of d34S and d18O of anhydrite from halite facies varies from +12.6 to +15.0‰ and +7.5 to +10.9‰ respectively. The quantitative ratio of pyrite content from the water-insoluble residue (silty-sand fraction) is characterized by extremely low (<<1%) to high (4–5%) steep gradation values. The increased presence of pyrite indicates the influence of bacterial sulphate reduction. The sulphate reduction process was more intense, especially when evaporites were formed in mud. The narrow fluctuation range of sulphur and oxygen isotopes values of the measured anhydrite indicates low levels of fractionation. It was established that during the Permian, evolutionary changes in the content of sulphate ions in sea water correlate with the sulphur isotopic composition of marine evaporites

    Opis:
    Fluid inclusions in halite can directly record the major composition of evaporated seawater; however, Ordovician halite is very rare. The Ordovician is a key time during the evolution history because profound changes occurred in the planet’s ecosystems. Marine life was characterized by a major diversification, the Great Ordovician Biodiversification Event and the Late Ordovician Mass Extinction, the first of the “big five” mass extinctions. However, so far there is no data on the Ordovician seawater. Data from the Ordovician-Silurian boundary were available only. In this study, we report the major compositions from Middle Ordovician halite in China to give the exact composition of Ordovician seawater. The basic ion composition (K+, Mg2+, Ca2+, and SO42-) of inclusion brines was established with the use of ultramicrochemical analysis. The data on the chemical composition of the brines in the primary inclusions indicated that the brines were of Na-K-Mg-Ca-Cl (Ca-rich) type, and cover a huge gap in the evolution of seawater chemistry. The chemical composition of the primary inclusion brine in halite confirmed the earlier results for the Cambrian and Silurian halite originating from other salt basins and the previous speculation of “calcite sea” during the Ordovician, indicating a higher potassium content in the Lower Paleozoic seawater than in the seawater of other periods of the Phanerozoic.

    Opis:
    Seismic data and core from the shallow cartographic Pilzno P-7 borehole were used to construct a new model of the Carpathian orogenic front between Tarnów and Pilzno, in the Pogórska Wola area (southern Poland). The most external, frontal thrust of the orogenic wedge (the Jaśniny structure) was identified as a syn-depositional fault-propagation fold de- tached above the Upper Badenian evaporites. Its formation was controlled by the presence of mechanically weak foredeep evaporites and by the morphology of the sub-Miocene Meso-Paleozoic foreland plate (Jaśniny and Pogórska Wola palaeovalleys). The frontal zone of the Carpathian orogenic wedge (the Skole thrust sheet and the deformed foredeep deposits of the Zgłobice thrust sheet) is characterized by significant backthrusting of the foredeep succession towards the south, and by the presence of a triangle zone, with strongly deformed Upper Badenian evaporites of the Wieliczka Formation in its core. The triangle zone was formed during the latest thrusting movements of the Carpathians. An indication of the existence of the triangle zone in the vicinity of Dębica has also been provided by reinterpretation of the archive regional geological cross-section. The youngest foredeep deposits, brought to the surface above the backthrust, have been dated as Sarmatian (NN7 nannoplankton zone), which indicates that the latest thrust movements within the frontal Carpathian orogenic in the vicinity of Tarnów-Dębica took place approx. 11-10 million years ago. Thermochronological studies (AFT and AHe) indicated that the foredeep succession drilled by the Pilzno P-7 borehole has not been buried deeper than 1.5-2 km, which is compatible with reconstruction based on the seismic data.
