The Black Sea basins structure and history: New model based on new deep penetration regional seismic data. Part 2: Tectonic history and paleogeography

A new lithostratigraphy scheme has been compiled for the Western Black Sea Basin and a new geological history scheme from Middle Jurassic till Neogene is suggested for the entire Black Sea Region. Continental rifting manifested itself from the Late Barremian to the Albian while the time of opening of the basins with oceanic crust was from Cenomanian till mid Santonian; origination of the Western and Eastern Black Sea Basins took place almost simultaneously. During Cenozoic time, numerous compressional and transpressional structures were formed in different part of the Black Sea Basins. It is shown that in Pleistocene-Quaternary time, turbidities, mass-transport deposits and leveed channels were being formed in the distal part of the Danube Delta.
