Abstract

In this article, based on the data on the convective heat transfer from the mantle wedge to the 2D heat flow anomaly observed in the rear of the Central Crimean arch, the angle of inclination of the mantle wedge and the rate of subduction of the East Black Sea lithospheric plate under the lithosphere of the Scythian continental plate (Crimean region) are estimated. The effects of the 410 km and 660 km phase transitions are taken into account. Within the framework of the geodynamic model constructed the horizontal extent of the 2D heat flux anomaly observed in the rear of the Crimea mountain belt corresponds to subduction velocity of ~ 40 mm per year which is close to that observed with the help of geodetic means. Ascending convective movements in the mantle can carry mantle calcareous-alkaline magmas (with hydrocarbon geo-fluids contained in them) into the near-surface layers of the Earth’s crust, and, consequently, oil and gas fields should be confined to zones located in the upper part of the lithosphere, above the convective vortices of the Karig.
