Abstrakt:	The results of magnetotelluric sounding along the 350-km long Blagoveshchensk-Birakan profile are discussed. The profile begins in the Longjiang-Selemdzha orogenic belt and ends in the Jiamusi-Bureya massif, thus intersecting the southern Amur-Zeya sedimentary basin from the northwest to the southeast. Twelve soundings have been performed in the broad range from 1 × 10 to 2 × 10 Hz. Geoelectric sections have been constructed for the depths of 2 and 150 km with the determination of the geoelectric parameters of the sedimentary cover within the basin and the identification of the zones of anomalous conductivity in the Earth's crust and upper mantle.
