Аннотация:The chemical composition of the bottom silty waters and more than 40 samples of brines with mineralization from 50 to 270 g/kg in the cores of the bottom sediments, taken in 2-nd cruise R/V <<Moscow University>> to south-east from island Crete was studies. The brines and silty waters with high mineralization were investigated in some hollows of Mediterranean Bank with saltdome tectonics. The increase salinity in the cores with diatomoceous-sapropel silts went on with sulphate-reduction and appearance of H2S. All waters samples and brines are magnesium subtype of sulphate type of the waters. Received data shown active influence of evaporits of Messinian on modern dithohydrosphere of the Mediterranea Sea.
