On the possibility of the Caspian and the Black Seas interconnection in the Late Pliestocene-Holocene

Abstract

An analysis of largest river valleys in the Manych region and geologic data has shown that Baer's mounds may be considered' to be formed by "flat water flow" coursed to Manych. Delta deposits of Kalaus river serve now as watershed between the Black Sea and the Caspian Sea. Kalaus and Yegorlyk rivers formed deep erosion incising during regressions and the history of seas' interconnection is close related to the development of these rivers. Author concludes that in the Late Pleistocene the water flew from the Caspian to the Black Sea and in the Early Holocene - in reverse. During this period shells of the Cerastroderma glaucum spread into the Caspian Sea along the Manych strait.
