GEOELECTRIC SECTION OF THE LITHOSPHERE OF THE KHANKA MASSIF ALONG THE POZHARSKOYE VILLAGE–SHKOTOVO SETTLEMENT PROFILE FROM MT SOUNDINGS

The geoelectric section of the lithosphere is constructed down to a depth of 150 km based on the results of MT soundings carried out along the profile crossing the Khanka Massif from north to south. The crust and upper mantle structure of the massif is investigated. It has been found that the Khanka Massif is divided into the northern and southern parts bordered by the northern restriction of the Spassk Zone. A higher resistivity observed in the upper part of the section and the upper mantle is typical of the southern part of the massif. The northern part is characterized by two extended low-resistivity areas located beneath the southern boundaries of the Matveevka and Nakhimovka zones that penetrate from the upper mantle up to the surface. A comparison of the results obtained with the seismic prospecting and gravimetric data has shown their direct or indirect consistency.
