A procedure for the simultaneous interpretation of magnetotelluric and near field transient electromagnetic sounding (MTS and NF TEMS, respectively) data is proposed. The advantages of the complex interpretation are demonstrated by specific examples. In accordance with the interpretation of the field data, geoelectrical sections of the lithosphere in the western part of the Chuya Depression are constructed. A reduction in the depth to the conductive crustal layer in the epicentral zone is found, and the geoelectrical boundary in the upper part of the paleozoic basement is revealed.
