摘要: Abstract This work is based upon results of interpretation about 8872 km-long regional seismic lines acquired in 2011 within the international project Geology Without Limits Black Sea. The cover nearly entire Sea Basins, including Russia, Turkey, Ukraine, Romania and Bulgaria sectors. A new map acoustic basement relief a tectonic structure scheme are constructed for Basins. includes areas with oceanic crust highly rifted continental crust. chain buried seamounts, which were interpreted as submarine volcanoes Late Cretaceous (Santonian to Campanian) age, has been identified north Turkish coast. On Shatsky Ridge, probable Albian age have also recognized. Synorogenic turbidite sequences Paleocene, Eocene Oligocene ages mapped. In Cenozoic, numerous compressional transpressional structures formed different parts Basin. During Pleistocene–Quaternary, turbidites, mass-transport deposits leveed channels distal part Danube Delta.
