Abstract

This paper presents the results of magnetotelluric (MT) studies performed within the Western Transbaikalia segment of the Central Asian fold belt along the Selenga River delta-Krasnyi Chikoi Village profile. The data are interpreted using the results of recent geological, petrological, geothermal, tectonic, and geochronological studies of the Mongolia-Transbaikalian part of the Central Asian fold belt, including large heterochronous igneous provinces and zones. The studies have shown that the investigated area has a complex geologic and tectonic structure produced by extensive rifting leading to the formation of large crustal blocks and by intense magmatic fluid activity along deep fault zones. The investigated profile is characterized by a combination of blocks with different types of geoelectric section—mountain ranges and intermontane basins separated by long-lived deep fault zones.
