Pasynkov A. Morphostructural differentiation of the Azov-Black Sea Basin of Ukraine and prospects for development of the region

The thesis is devoted to the morphostructural differentiation of the Azov-Black Sea Basin, characteristics, conditions and stages of formation of the morphostructures and morphosculptures of the Black and Azov Seas. The principles of the morphological differentiation have been elaborated, the rational strategy of study of the morphostructures has been formed, the criteria and factors of the singling the morphostructural regions out have been substantiated. The map of the morphostructural differentiation of the Azov-Black Sea Basin with the scale 1:500 000 has been made for the first time. The basic morphogenetic types of the morphostructures of the shelf, continental slope and deep-water depression of the Black Sea and basin of the Azov Sea have been singled out. Singled out morphostructural provinces, sub-provinces, regions and districts that were described in details have been studied. The perspectives of the basin explorations and of the rational developing of the sea bottom, from the standpoint the morphostructural differentiation of the region takes on special significance in three practical aspects: steady raising of the mineral-raw material base of Ukraine, determination of the stability rating of the marine geosystems for building underwater and over water objects, determination of the specific geo-ecological characteristics in every region for minimization of the negative influence on the aquatic ecosystem.
