?tepnická skala Klippe – unique type of the Czorsztyn Succession (Pieniny Klippen Belt, Western Carpathians)

摘要

?tepnická skala represents a specific klippe of the Czorsztyn Succession (Pieniny Klippen Belt). The specificity of the klippe is prevalence of non-condensed micritic limestones over the condensed, Ammonitico Rosso-type limestones. The stratigraphic succession starts with pink to reddish crinoidal limestone (Krupianka Limestone Formation – Bajocian), which is overlain by nodular limestones of the Ammonitico Rosso facies (Czorsztyn Limestone Formation – Bathonian). Then follows thick Bohunice Formation (Bathonian-Lower Tithonian) which shows large lateral and vertical variability. Therefore this formation was subdivided to new-defined members: Medné Limestone Member (Bositra coquina – Bathonian-Callovian), micritic/crinoidal ?tepnice Limestone Member (Callovian-Lower Oxfordian), micritic Babiná Limestone Member (Upper Callovian-Oxfordian), Ko?kovce Limestone Member (ammonite coquina – Oxfordian) and Saccoccoma Stre?enice Limestone Member (Kimmeridgian-Lower Tithonian). In the Babiná Limestone Member, flat mound with stromatactis-like structures is visible. It was formerly interpreted as true stromatactis mud-mound but it lacks signs of microbial cementation which are typical for stromatactis mud-mounds. Bohunice Formation is overlain by Dursztyn Limestone Formation with very similar facies development (Tithonian-Berriasian).
