Abstract: | The study area is the South Tatarstan Arch located in the Volgo-Ural Region, which is an enigmatic crustal segment occupying
one third of the East European Platform. Monitoring studies have shown that fluid discharge processes are still active and
time-dependent. This paper presents an integrated review of the geological, geophysical, hydrochemical and geochemical studies
of the crystalline basement of Tatarstan. These studies are based on the stratigraphic and compositional schemes within the
crystalline basement, the drilling of deep wells, the geodynamic activity of the fractured zones of the crystalline basement
and the presence of fluids therein. Furthermore, the changes in the chemical composition of the basement waters are taken
into account. |
