This paper gives detailed evaluation of lithofacies, biostratigraphy and paleotectonics of the sections recording the Jurassic to Lower Cretaceous sedimentation in the Tatric Superunit of the Male Karpaty Mts with a special emphasis on the Kadlubek treshold zone. The sequence consists of two distinct sedimentary megacycles. The Liassic megacycle was represented by the Dudziniec Formation resting with angular disconformity on the Triassic sequence. The Middle Jurassic to Lower Cretaceous megacycle is separated from the underlying sequence by a significant Toarcian condensation-erosion event. A tensional episode in the adjacent Penninic rift zone, which caused this event, was accompanied by the origin of a series of listric faults. Several systems of neptunian dykes have been recognized. The article also describes finds of biostratigraphically valuable microfauna and the distribution of the Upper Liassic brachiopod and bivalve associations from the Tatric area. The composition of these associations does not coincide with the division on the ”Tethyan” and ”European shelf” assemblages: the fauna of the basinal bottoms belongs to the former one, the inhabitants of the bottom elevations to the latter group.
