The clasts represent mainly the Malm deposits but also clasts with radiolaria limestones of the Early Cretaceous age were found. It can have an important influence on geodynamic evolution of the Gresten unit and its relation to other units.

The Late Badenia salts developed in two separate an echelon-like sub-basins, the western and eastern Carpathian ones. During the Late Miocene movement a substantial part of the salt deposits were incorporated in the folded zone in front of the Carpathians-Zgłobice Unit in the west and the Sambir and sub-Carpathian units in the east (Ukraine and Romania respectively).

The Polish and Ukrainian Outer Carpathians form the north and northeastern part of the Carpathians that expand from the Olza River on the Polish-Czech border to the Ukrainian-Romanian border. Traditionally, the Northern Carpathians are subdivided into an older range, known as the Inner Carpathians, and the younger ones, known as the Outer Carpathians. These ranges are separated by a narrow, strongly tectonized belt, the Pieniny Klippen Belt. The Outer Carpathians are made up of a stack of nappes and thrust sheets showing a different lithostratigraphy and tectonic structures. Generally, each Outer Carpathian nappe represented separate or partly separate sedimentary subbasin. In these subbasins, enormous continuous sequence of flysch-type sediments was deposited; their thickness locally exceeds 6 km (3.7 mi). The sedimentation spanned between the Late Jurassic and early Miocene. During the folding and overthrusting, sedimentary sequences were uprooted, and generally, only sediments from the central parts of basins are preserved. The Outer Carpathian nappes are overthrust on each other and on the North European platform and its Miocene-Paleocene cover. In the western part, overthrust plane is relatively flat and becomes more and more steep eastward. Boreholes and seismic data indicate a minimal distance of the overthrust of 60-80 km (37-50 mi).

Very well exposed, long and available for studies profile allow to familiarize with development of shaly-mudstone beds and geological fossil processes responsible for high accumula-tion of organic matter in the Veřovice Formation resulted by anoxic conditions of their sedimentation.

During the first, extensional stage, in the Late Jurassic (Kimmeridgian – Tithonian) the proto-Silesian Basin was formed in the area of the Outer Carpathian sector of the Northern Tethys. To the south the basin was bordered the by Proto-Silesian Ridge and to the north it was limited by the southern margin of the Northern European Platform. During the Late Jurassic - Early Cretaceous times the proto-Silesian Basin was filled by mainly flysch deposits, with dark-grey or black mudstones and marly shales accompanying sandstone or calcareous turbidites. At the end of Early and beginning of Late Cretaceous the extensional stage evolved into the compressional regime; consequently, the proto-Silesian Basin was divided into a few separate basins and ridges. The sedimentary infill of the Silesian Basin, which originated in the southern area, is now represented by the Silesian Napp...

Today this ridge is destroyed totally and is known only from olistoliths and exotic pebbles in the Outer Carpathian flysch. It separated the proto-Silesian Basin from the Alpine Tethysduring Jurassic-Early Cretaceous times.The carbonate platform was initially developed on this submarine ridge providing excellent conditions for organic life, represented by calcareous algae, sponges, corals, bryozans, brachiopods, bivalves, ammonites and crinoids. The Late Cretaceous uplift of the Silesian Ridge produced a tremendous amount of clastic material.The submarine fragments of the Silesian Ridge provided favorable conditions for development of shallow banks with the carbonate platform sedimentation during Paleocene-Eocene times. Shallow water, probably narrow shelf locally was dominated by Paleocene an...

The hill is locacted in southern part of Wadowice town, notherly of Gorzeń Dolny village. Szydłowiec Sandstones, Paleocene in age, are a lithostratigrafic division of the Subsilesian Series. They are overlied by the Paleocene Gorzeń Sanstones and presumably underlied by the Cretaceous variegated marls. The Szydłowiec Sandstones are predominate by thick-bedded coarse grained and conglomeratic sandstones. Occasionally conglomerates occur there. The sandstone complexes are intercalated by not numerous thin layers of shales or thin-and medium-bedded shally-sandstone flysch. The sandstones are usually cemented by carbonate matrix. In the grain composition of sandstones quartz predominate, others are represented by metamorphic and magmatic rocks, as well as sedimentary rocks, mainly o...

The bulk of the exposed succession is made up of inclined Frasnian limestones overlain by Famennian condensed limestones and marly/shale deposits (Szulczewski, 1978, 1981; 2010 and references therein). The Kadzielnia succession is divided into five lithostratigraphic units (mostly informal) that include: • The Kadzielnia Limestone Member, interpreted as a mudsupported microbial to reef mound (~50 thick; Fig. 5) composed of massive boundstones with stromatactoid structures (Narkiewicz et al.

In the Katanga Supergroup succession of the Lufilian Belt (Zambia and the DRC), the first stage of rifting (ca. 880 Ma) is recorded by the transgressive Roan Group that evolves from the continental clastic strata to the carbonate platform prograding from the south. Major uplift (≥765 Ma) in the southern part of the Roan rift basin terminated d...
