- Аннотация: Recent studies of the Crimea give us new data for the interpretation of Early Cretaceous history of the region, which differs from the previous data. Shortly, it could be established as following. (1) The compression and later extension in the latest Berriasian – E. Valanginian resulted in the formation of complex graben system. The Plain Crimea was an uplift; the basin deepen to the S and the Mountain Crimea was mostly submerged. (2) L. Valanginian – E. Hauterivian phase was marked by the northward tropical sea transgression and formation of complex facial system in slow extensional conditions. (3) During the L. Hauterivian – Aptian the whole area quickly subsided. The Mountain Crimea was overlapped by uniform pelagic facies. The sea covered Plain Crimea almost completely and Boreal water mass reached this area in the Late Hauterivian. (4) The new uplift and folding event of the Mountain Crimea took place in the E. – M. Albian. In contrast, back-arc rift system was formed in the Plain Crimea, where volcanic sediments appeared. (5) During the latest M. Albian – L. Albian rifting event and a series of transgressions lead to the submersion of the Mountain Crimea and possibly to the Black Sea opening.
