Jurajskie utwory sukcesji czertezickiej profilu Góry Zamkowej masywu Trzech Koron w Pieninach

Abstract

Middle to Upper Jurassic of the Zamkowa Mt (Trzy Korony massif) in the Pieniny Klippen Belt show special development of the Czertezik Succession. The section reveals very thick units of crinoidal limestones: the Smolegowa Limestone Formation grainstones abruptly laterally replaced by crinoidal-spiculitic grainstones of the Flaki Limestone Formation, these are overlain by strongly condensed pelagic limestones - in their uppermost part rich in planktonic foraminifers and radiolarians - with abundant detrital grains of quartz and dolomite, fragments of crinoidal limestones, and the glauconitic nodules (glaucony). Both the development of attaining large thicknesses of strongly facies contrasted crinoidal units supplied from overhanging »crinoid gardens«, as well as the appearance of abundant grains in younger pelagic limestones, prove the synsedimentary faulting which produced an active tectonic scarp during the Bajocian and at the turn of Callovian and Oxfordian.
