Extensional synsedimentary faulting (neptunian dykes and submarine scarp breccias) took place during the Bathonian-Callovian and was reactivated during the Oxfordian and Berriasian. Six lithostratigraphic units were characterized microscopically by the frequencies of their constituents. Red, sometimes sterile micrite cement in the voids display marine pattern according to O, C isotopes. Terrigenous admixture in the Lower Cretaceous limestones testified to the existence of an emerged elevation along the outer part of the Czorsztyn sedimentary zone. A new lithostratigraphic unit — Krasin Breccia — is introduced.
