Fold-thrust dislocations in sedimentary cover of the Sea of Azov

As follows from geological and geophysical data, tectonic deformations formed under lateral compression are widespread in the sedimentary cover at the bottom of the Sea of Azov. Fold-thrust dislocations are established in the North Azov Trough on the southern slope of the Ukrainian Shield, in the Azov Swell of the young Scythian Plate, and in the Indol-Kuban Foredeep. The transregional Main Azov Thrust Fault and smaller thrust faults of listric morphology tens of kilometers in extent are known. Asymmetric anticlines are related to their fronts. In plan view, the crests of these anticlines are displaced down the dip of the controlling faults. Folds and thrusts developed in pulsatory manner in the regime of periodically acting tangential compression are recorded in the thickness of the plate complex and stratigraphic and angular unconformities. Some of these dislocations are active and accompanied by anomalously high formation pressure, temperature and hydrochemical anomalies, tectonic brecciation, and mud volcanoes.
