Regional Aspects of Recent Tectonics of Tatarstan Republic (Russia)

In this paper intensity and direction are set, absolute and relative amplitude values of the latest movements in Tatarstan on the first order tectonic structures are calculated. Republic's territory is divided into zones according to the latest movements' regime. It is established that Tatar Arch has acquired its modem structure in recent times due to positive movements of the crystalline basement, and morphogenesis of South-Tatar Arch was completed in Neogene-Quaternary age. There is a direct dependence between oil content scale and neotectonic movements' intensity in Tatarstan. The existing oil content scale of South Tatar Arch is predesignated by existing regime of its neotectogenesis. During upward regime of recent movements, positive structures cause directed toward them oil fluids flow from intervals or areas of their generation through faults system activated currently. During downward regime, on the contrary, hydrocarbons are squeezed out of structure, i.e. within south-eastern part of Tatarstan upward and downward latest deformations create compression-decompression effect in the sedimentary cover.
