SEDIMENTOLOGY AND BRACHIOPODS OF THE LOWER JURASSIC LUTY POTOK LIMESTONE (SLOVAKIA, WEST-CARPATHIAN KLIPPEN BELT)

The crinoidal Luty Potok Limestone formerly considered as a Middle Jur assic part of the Czorsztyn Succession contains Liassic brachiopods an d fragments of sponge skeletons. It belongs to the Nizna Succession. C lastic admixture derived from an external source is identical in both successions deposited on the opposite margins of the Pieninicum sedime ntary zone. The Luty Potok Limestone is,penetrated by a swarm of neptu nian dykes which originated during repeated movements along a Liassic synsedimentary fault zone.
