Geoelectric section of the lithosphere in the central part of the Middle Amur sedimentary basin (Far East) based on the magnetotelluric sounding data

Results of magnetotelluric soundings (MTS) along the profile plotted across the strike of the Middle Amur sedimentary basin are considered. The results of field studies are analyzed and different factors influencing the behavior of sounding curves are discussed. A reference curve and reference geoelectric section selected on the basis of the previous MTS works within the Middle Amur depression allowed us to compensate for the influence of different geoelectric inhomogeneities and construct a starting model for two-dimensional mathematical modeling based on the field data. As a result, a geoelectric model of the lithosphere structure in the Middle Amur sedimentary basin across its strike was compiled.
