Abstract

The peculiarities of the structure of Cretaceous–Eocene boundary deposits in the Belogorsk district, Central Crimea, are considered. Tectonic structures interpreted as paleoseismodislocations are revealed and described; their age, structures, and evolutionary history are characterized; the magnitude and intensity of the seismic paleoevent are estimated. The position of steeply dipping fractures in Cretaceous rocks is regular and related to the bedding along the dip and strike of the structure. Their formation was caused by transverse extension in the background of general uplift at the beginning of Eocene, coincided in time with the main folding phase in North Turkey.

Keywords:
