Eocene seismicity and paleogeography of the Central Crimea

Abstract
The article considers the results of a comprehensive study of the Cretaceous-Eocene deposits of the Central Crimea (Ak-Kaya mount.). The temperature and salinity of the formation of Maastrichtian and Eocene rocks have been determined, and a correlation has been made with the global climatic event EЕСO (Early Eocene Climate Optimum). The synchronicity of the formation of steep submeridional fractures and the basal horizon of the Eocene has been proved. Three major stages of deformation have been identified: pre-Eocene, Eocene, and post-Eocene. It is shown that the Eocene stage corresponds to the formation of paleoseismic dislocations during the main phase of tectonic activity in the Pontids (Eastern Turkey).
