Abstract
The organic-rich sediments were deposited during the marly stage of the proto-Pieniny basin evolution (Early Jurassic-beginning of Middle Jurassic) when this basin was relatively narrow, before the origin of Czorsztyn Ridge. After the ridge uplift sedimentation changed from anoxic to oxic, calcareous. The Rock-Eval pyrolytical analysis revealed that the Aalenian-Early Bajocian black spherosyderitic shales of the Skrzypny Shale Formation are enriched in the organic matter, but the character of kerogen and TOC content indicate the lack of good source rocks within the Middle Jurassic of the Pieniny Klippen Belt.
