Abstract: | Magnetotelluric method is widely applied to study the Russian part of the East-European Craton, as well as the Caucasus and
the Urals: several thousand soundings were performed during the last few years. Their periods range is approximately from
0.003 to 3000 seconds, which allows to study the sedimentary cover and the consolidated crust. Resistivity cross-sections
along several regional profiles which run across the tectonic structures of the East-European Craton and the adjacent folded
systems were obtained, mainly using 1D and 2D interpretational tools. MT investigations provided important information about
the structure and reservoir properties of sedimentary complexes, the state of active geodynamic regions, the graphitization
and fluid regime of the consolidated crust, and the permeable and fluid-saturated crustal zones. |
