Russia, 22-30 September, 2015https://dspace.onu.edu.ua/handle/123456789/19430It is known that about 14 million years ago, a division of the Tethys Ocean occurred into the Mediterranean Sea and the Sea-Lake of the Paratethys. During the next 10 million years, its water area decreased in size, the sea-lake became shallow, and eventually subdivided into the Azov, Black, and Caspian seas. The first stage of the Paratethys closure was the Sarmatian Sea-Lake (14.0-10.5 million years ago). The initial water was salty as in the ocean. Then, as a result of the large inflow of freshwater, there was a Ireshening of the sea water. During Meotian time (10.5-7.0 million years ago), the Mediterranean salt water got into the sea-lake. Then, there was water desalination in the Meotian Sea. During this entire period, the level of the sea-lake changed with a trend towards a decreasing level. .Approximately 6-5 million years ago, in the Balakhanian stage (the beginning of the Pliocene), the sea- lake level decreased significantly, and it separated into the Black and Caspian seas.enSarmatian Sea-LakeBlack Sea region evolutionArticle
