Middle Devonian conodonts and structural implications for Świętomarz : Śniadka section (Holy Cross Mountains)

摘要: The paper presents a new interpretation of the geological structure and stratigraphy Devonian in Świetomarz–Śniadka section. uppermost Śniadka Formation (equivalent to Nieczulice Formation), was described previously from northern part section between exposures sandstones shales Świetomarz Formation. present study revealed presence mentioned area Sitka Coral-Crinoid Limestone Member Sierzawy Member, referable Skaly Black, thin-bedded limestones, occurring here, were assigned upper Member. Conodont assemblages indicate that corresponds hemiansatus Zone, whereas most represents timorensis – rhenanus/varcus zones. North American species Icriodus janaea is documented for first time Poland. Clay marls with Maenioceras terebratum are considered be These stratigraphic data basis Bodzentyn Syncline.
