Abstract
The paper analyzes the data from the Yamm-Torzhok regional profile intersecting the Ilmen electrical conductivity anomaly along its major axis. This work continues the long-term research on the structure of the Precambrian basement complexes in the western part of the East European Platform conducted by the Department of Geophysics of the Faculty of Geology of Moscow State University and Geoelectromagnetic Research Center of the Schmidt Institute of Physics of the Earth of the Russian Academy of Sciences (GEMRC IPE RAS). The obtained data combined with the analysis of the potential fields are used to construct a deep geoelectric model. Separately, a model of the structure of the sedimentary cover is presented.
