General regularities of a sedimentary cycles in epicontinental basins with terrigenous sedimentation

<jats:p>The results of facies analyses of Jurassic-Lower Cretaceous sections of Western Siberia, the Upper Palaeozoic of the Taimyr, Tunguska and Pechora basins, and the Vendian deposits of the Baltic Syneclise are summarised. Has been developed the conceptual sedimentological model describing the migration of depositional conditions during sea level changes in epicontinental paleobasins of humid climate. General regularities of the structure of transgressive-regressive layer sequences were established. The results obtained represent an effective tool for paleogeographic reconstructions and sequential analysis of terrigenous grey facies in geologic history regrades of their geotectonic position and paleogeography location.</jats:p>
