Abstract
In recent years representatives of the Department of Geophysics of the geological faculty of Moscow State University carried out geological-geophysical investigations of buried river valleys in the territory of Kaluga region. When solving this task, the most effective is the complex of methods, including geometrical soundings (VES) and induction low-frequency methods electromagnetic survey (TEM). As a result of joint interpretation of VES and TEM data within the horizontally layered subsurface the geoelectrical section satisfying observed data of both methods was obtained. Preliminary results of the interpretation show that the buried paleovalleys of different age represented mainly by sands appear in the geoelectrical model in the form of local objects of high resistivity against the background of a horizontally layered host section.
