Evolution of the Northern Caspian Sea Region and the Volga delta in the late Pleistocene-Holocene

On the basis of geologic-geomorphologic studies, an alternative concept regarding the evolution of the Northern Caspian Sea Region and the adjacent areas in the boundary of the Pleistocene-Holocene is presented. A supposition is made about the existence of a large lagoon in the North Caspian Region that the Volga River emptied into forming a delta. Later, water from the lagoon flowed as a “stratum” stream into the Black Sea through the Manych Strait. A conclusion is reached that the Baer mounds were formed on the bottom of this stream.
