According to the latest ideas, the Dnieper-Donets Depression is a transverse avlacogen that arose in the late stages of the Russian Platform development in the Middle Devonian, when not only the platform basement but also a significant part of the platform cover had already been formed...

The main ideas about the tectonics of the Mountain Crimea were obtained as a result of the works of K. K. Focht, A. A. Borisyak, A. S. Moiseev, V. F. Pchelintsev, M. V. Muratov, G. A. Lychagin, G. X. Dickenstein and many other researchers.The material presented in this article was collected by the author during ten years of research in the Mountain Crimea and route thematic works in the Western Caucasus.About tectonic zoning of the Crimea. The mountainous Crimea is a fragment of a large inherited vaulted uplift of Neogene age. The southeastern part and southwestern pericline of this uplift are cut off by northeastern and northwestern strike-slip faults and are submerged in the Black Sea. The northwestern wing of the Neogene uplift dips gently towards the Plain Crimea and, judging by the occurrence of Upper Cretaceous and Tertiary sediments, is associated with the marginal structures of the platform part of the peninsula - the Alma Syneclise and the Simferopol uplift - without significant disjunctive faults....
