Deformational structures (tectonic planes with slickensides, folds, parageneses of fractures) аre described  in the Upper Cretaceous — Neogene sediments of the southwestern Crimea. The purpose of the study is to clarify the scope and types of deformation in the Alpine orogenese stage. Strike-slip planes are dominated in the studied structures. Slickensides of reverse and thrust type account for 20% of all fractures. Deformations of various types are concentrated in the most plastic rocks and weak zones. The rest of the Upper Cretaceous and Cenozoic sediments have monoclinal bedding. It is shown that some part of  the deformations in the rocks of the Tauric series and of the rocks of Middle Jurassic - Lower Cretaceous age could occur during the Alpine period. The geological data are given, which confirm the presence of compression structures for all the Mountainous Crimea during the Alpine stage. Orientation of the restored axes of stress field shows that compression deformation is caused by pressure of the Black Sea microplate towards Crimea. The strike-slip-type deformations, within the studied area, dominate over the reverse type ones. Folded-thrust deformations are located more to the south — in the continental slope and shelf respectively, in the interaction area of the Black Sea microplate and the Crimea.
