ИСТИНА

Application of geophysical methods in geomorphological studies is aimed at the reconnaissance of drill core locations and interpolation between cores: tracing of lithological and stratigraphic boundaries, as well as the determination of bedding type within individual strata (horizontal, crossing, etc.) which is important for interpretation of their genesis. Our study was conducted in the upper Dnieper River basin, north-west of the Russian Plain, where no particular research has been conducted in the last 40 years to clarify the maximum glaciation boundary. We carried out ground penetrating radar and electrical resistivity tomography investigations to assess the geological composition of the active and abandoned Dnieper valleys downstream from Smolensk, which is crucial for understanding the river flow rerouting during the last glacial epoch.
