Nieciągłości sedymentacyjne w dolnym kimerydzie południowo-zachodniego obrzeżenia mezozoicznego Gór Świętokrzyskich

Abstract

SEDIMENTARY DISCONTINUITES IN THE LOWER KIMMERIDGIAN OF THE HOLY CROSS MTS.Results of investigations of the discontinuity surfaces in the Lower Kimmeridgian limestones and marls of the south-western Mesozoic margin of the Holy Cross Mts. are reported. Sedimentary discontinuities, indicated by surfaces representing the various stages of the consolidation of the deposit during non-deposition, have been distinguished on the basis of paleoecologlcal and lithological analyses. The evidence now available suggests a very shallow zone of the formation of these surfaces in high-energy marine environment. Breaks in sedimentation were probably connected here with intermittently retarded subsidence.
