Abstract: This article presents the results of experimental studies of the geoelectric structure of the crust held in Karelia. For research the authors established 5 highly ternary magnetovariational stations GI-MTS-1 separated by 5-10 km apart. The frequency of data recording was 50 Hz. To analyze the changes in apparent resistivity with depth at all 5 locations the authors perofmed processing of input data by two methods - magnetotelluric and phase-gradient sensing. To determine the apparent resistivity in each of the magnetic stations authors determined the apparent magnetotelluric resistivity of the earth's crust and changes in the system of resistivity with depth. Preliminary processing results revealed a number of conductive layers in the earth's crust at depths of 2-3 and 15-20 km, probably related to the shungite-bearing horizons. Comparison of methods for the interpretation of magnetotelluric and phase gradient sensing has shown their good match.
