The Cyclic and Sequence Stratigraphic Characteristics of the Visean–Serpukhovian Deposits in the Southern Part of the Moscow Syneclise

详细

The composition and origin of the Visean–Serpukhovian deposits in the southern part of the Moscow Syneclise have been characterized based upon generalizations of our own results and analysis of published and unpublished data. The levels of karst-influenced rocks correspond to the shallowest biogenic carbonate organogenic-clastic sediments of the initial and final phases of the eustatic cycle, i.e., the early transgression (transgressive system tract) and the late regression (the second half of the high-standing tract). Alluvial sands of the Oka River have been found in the karst cavities. A generalized model of the sequence has been proposed and a sequence stratigraphic interpretation of the studied section has been carried out.
