Abstract

The geoelectric section of the lithosphere was constructed down to a depth of 150 km based on the results of magnetotelluric (MT) sounding carried out along the profile that extends along the eastern edge of the Khanka massif to the coast of the Sea of Japan, from the northern part of the massif to the Sikhote-Alin fold system (SASS). Conductive zones in the crust and zones of increased electrical resistivity in the upper mantle were distinguished. Differences in geoelectric characteristics of the Earth’s crust in the Late Proterozoic–Paleozoic Khanka massif and in the Tsentralnaya zone of the Albian-Cenomanian SASS were revealed. The latitudinal zonality of the crust and upper mantle was confirmed. The influence of the coast effect on the behavior of the Wiese vectors was studied and their relationship with conducting zones in the crust and faults was shown.
