Basins of the Ligurian, Adriatic, Black, Caspian and South China seas have been subdivided into regions according to their recent engogenic regimes, stages of evolution and phases of activity; the subdivision was based on the earthcrust typizationby four characteristics (heat flow density, the crust thickness, present-day elevations and depth of consolidated basement). Spatial interrelations between taphrogenic and platformian regimes are elucidated, as well as various stages of the taphrogenic regime. The authors conclude that the sea basins under consideration form an evolutionary genetic sequence of structures resulted from large tectonic collapse of continental crust, at present the endogenic activities decrease.
