Геоморфологические и литологические признаки существования "пластовых" потоков в Северном Прикаспии в позднехвалынское время

Аннотация

Channel-like depressions, wide and shallow depressions of different shape, small ovals with degradations, typical Baer's mounds with adjacent lakes are considered as the members of unique genetic sequence, All these landforms were formed when large amount of water overflowed from the Caspian Sea to the Black Sea along the vast plane with little grade. They are analogs of big riverbed ridges, which arise due to macro-scale turbulence of the flow. The Baer's mounds are manifested best within the Volga delta because of their large height, the abrasion during New-Caspian transgression, the washout of the lesser forms and the swamping the between-ridges depressions. The most intensive "bedded" flows took place admittedly during Late Khvalyn transgression.
