Zusammenfassung:The structural position of the Black Sea deep-sea depression is generally determined by its location in the area of intersection of diagonal transcontinental tectonolineament belts. The different thickness of deposits of the same age in different depressions emphasizes the bloc structure of the earth's crust in the water area. Space photographs clearly show the contours of the depression are enveloping by the long arcs of the mountain ranges and valleys of the Caucasus, Ajaro-Trialetia, and the Eastern and Western Pontides. Such large oval and arcuate, partially sequentially superimposed structures (the Miesian plate, Pannonian and Bohemian massifs) are characteristic of the entire southeastern border of the East European platform and reflect the activity of the processes of destruction of its southern foreland in the zone of development of the classic geosyncline. The available data allow us to assume the superimposed nature of the Black Sea depression, formed as a result of mainly vertical tectonic movements in the field of development of mantle plume activations.
