The Structure of Quaternary Deposits in the Upper Dnieper Valley According to Integrated (Combined) Geophysical Data

Abstract: The ground penetrating radar (GPR) and electrical resistivity tomography (ERT) geophysical methods were used for geological mapping, location of lithological boundaries, and description of the inner structure of sediments of the Upper Dnieper zone, as well as for locating optimal sites for drilling and correlating borehole cores. The geophysical information we obtained allowed restructuring of the upper Dnieper valley due to Valdaian glaciation to be identified. The GPR data in the frequency range of 50–250 MHz enabled description of the upper part of the geological section; ERT provided data up to a 80–100-m depth. Modified focusing inversion based on the major boundaries obtained with GPR was performed to correct the ERT inversion model. © 2020, Allerton Press, Inc.
