The Anthracosia Shales are lacustrine deposits within the volcano-sedimentary Pennsylvanian– Lower Permian succession of Intra-Sudetic Basin. Core from Rybnica Leśna PIG 1 borehole, which penetrated Shales, was analysed to explore influence climate on evolution palaeolake, as distinct tectonic and volcanic forcing. This reconstruction made using mineralogical geochemical proxies (elemental composition, TOC values, presence framboidal pyrite siderite). Based results, three chemically...

Abstract Terminal Triassic environmental changes are characterized by an integrated study of lithology, litho- and cyclostratigraphy, paleontology, mineralogy, geochemistry rock magnetism in the Tatra Mts. The Carpathian Keuper sequence was deposited arid environment with only seasonal rivers, temporal lakes swamps scarce vegetation. Combination a wide range δ 18 O values (-0.7 to + 2.7) negative 13 C documents dolomite precipitation either from brackish or hypersaline lake water, its...

This study details the petrology and chemistry of Oligocene succession Grybów Nappe in its stratotype-locality tectonic window (Polish Carpathians). The section studied is composed Sub-Grybów Beds, Marl Formation (GMF), Cergowa representing middle to upper part succession. rocks consist quartz, calcite, Na-plagioclase, muscovite clay minerals (illite-smectite with 25–30% smectite kaolinite). Additionally, hematite occurs GMF chlorite respectively. macerals assemblage dominated by...

The Oligocene Grybów Succession is recognized as a counterpart of the anoxic Menilite Formation. Its comprehensive geochemical investigations are made in key sections Ropa Tectonic Window (the Unit, Polish Outer Carpathians). maceral assemblages, dominated by land-plant liptinite, vitrinite and intertinite, correspond to kerogen types II III. A Tmax vs. HI diagram shows terrestrial type with various additions III algal I. variation δ 13 C org. (from –25.21 –27.38‰) may have resulted from...

Abstract The Grybów Unit occurring in the Ropa tectonic window was subject of micropaleontological and geochemical investigation. Studies, based on calcareous nannofossils, proved that level reworked microfossil is not higher than 22 % it varies between two sections. Quantitative analyses assemblages confirmed domination Cretaceous Middle Eocene species. Sub-Grybów Beds, Marl Formation Krosno Beds were assigned to Late Oligocene represent terminal flysch facies. Detrital material accumulated...

The chemical composition of the Cretaceous deposits Grajcarek thrust-sheets (Pieniny Klippen Belt, Poland) has been investigated to provide information on palaeoenvironment and provenance pelagic turbiditic particles. material studied shows large variations in terrigenous biogenic content. Phyllosilicates (mirrored amounts Al2O3, average 15 wt.%) carbonates (6 wt.% CaO) are common mineral components excluding Cenomanian radiolarian shales (CRS) that enriched silica (mean content SiO2 is 64...

Abstract The Ostravice Sandstone Member was identified and described as a lithostratigraphic unit in the Polish part of Outer Carpathians. This division occurs lowermost Godula Formation, is underlain by variegated deposits Mazák Formation or directly Barnasiówka Lhoty formations, overlain Czernichów Formation. Domination thick- very thick-bedded sandstones, conglomeratic sandstones conglomerates rich calcareous clasts, mostly Štramberk-type limestones, typical for Member. These are...

The study area comprising the cantral part of Polish Lowlands, termed Mogilno-Łódź Synclinorium. This could be important petroleum exploration target in Poland, especially for unconventional resources. In this paper, we evaluate organic source facies and results basin modelling order to improve understanding regional system. Geochemical petrographic analyses potential rocks were used study. Our investigations showed that carbon contents is high – up 7.5% wt% Upper Jurassic even 5.5 Middle...

Anthracosia Shales within the Pennsylvanian-Lower Permian continental succession from Intra-Sudetic Synclinorium are lacustrine sediments, represented by black shales intercalated with sandstones/mudstones. Mineral composition o f each lithology consists quartz, feldspar, mica, clay minerals (including kaolinite, content which decreases upward sec tion), and carbonates (calcite siderite).The section is a continuous record reduction rise in terrigenous input.Mineral detritus least weathered...

A b s t r a c t. Coal-bearing conglomerates occur in the Menilite Formation of Silesian Unit, outcropped village Kobielnik.Coal particles are angular and differ size (2 mm-6 cm).The examined coal shows rather predominance vitrinite (collotelinite, collodetrinite, vitrodetrinite).However, presence inertinite (fusinite, semifusinite inertodetrinite with accessory funginite secretinite) is also significant.However, liptinite (sporinite, cutinite resinite) indicates its maceral composition.The...

Calcareous arenitic rocks exposed in the Dopplerhütte and Tulbingerkogel quarries northwest of Vienna were studied to establish their stratigraphic age.The whole succession is a part "Northern Zone" -the thrust sheet -which represents external Wienerwald Flysch.These regarded commonly as Neocomian, however analyses foraminifera within intercalations marly limestones proved presence Globorotalia sp. assemblages with index species Spiroplectinata annectens (Parker et Jones).Therefore,...
