The East European Platform (EEP) in Poland belonged to Baltica plate during Cambrian and Ordovician times. Baltica originated as a result of disintegration of supercontinent Pannotia, which occurred during Early Cambrian. Baltica included part of Poland and adjacent areas northeast of Teisseyre -Tornquist zone. This zone is associated with Teisseyre - Tornquist Line, which ran from Scania through Western Pomerania, central Poland to the Black Sea. The Baltica plate originally included also area south-west from thi...

The West Carpathians consist of an older, internal orogenic zone known as the Inner or Central Carpathians and the external, younger one, known as the Outer or Flysch Carpathians. The Outer Carpathians are built up of a stack of nappes and thrust-sheets showing a different lithostratigraphy and tectonic structures. The Outer Carpathian nappes are thrust over the North European Platform and its Miocene-Paleocene cover. They correspond to more or less separate sedimentary basins and every basin generally displays a ...

The Outer Carpathians contain organic-rich rocks, deposited in the basins belonging to the Tethys realm during Jurassic-Late Cretaceous and to the Paratethys realm during Oligocene times. The Alpine Tethys developed during the Early-Middle Jurassic times. The Aalenian-Lower Bajocian dark shales of the Skrzypny Formation and Upper Cretaceous-Paleocene Ropianka Formation were deposited in this realm. The Protosilesian Basin, which constitutes the northern part of the Western Tethys, developed as back-arc basin north...
