Summary In 2019, comprehensive geophysical work was completed on the regional 22 km profile across the Ugra river. The work was carried out for several years by a group of employees and postgraduate students of the Department of Geophysics of the Geological faculty of Lomonosov Moscow state University during educational and optional geophysical practices [Kulikov et al., 2016]. The geophysical complex included works using audio-magnetotellurics sounding (AMTS), time domain electromagnetic (TDEM), and vertical electric sounding with measurement of induced polarization (VES-IP). Based on the results of a complex interpretation of electrical data, a deep resistivity model was constructed. The most interesting result is the allocation in the Central part of the profile multi-tiered system of paleovalleys with different ages ‒ Visean, Neogene, Quaternary. |
