Integrated Geophysical Studies of an Esker in the Kaluga Region

Resumo

This paper discusses integrated geophysical studies of an esker body in the Kaluga Region. An apparent polarizability anomaly was investigated. Integrated interpretation of geophysical data, drilling results, and core analysis made it possible to clarify the nature of the anomaly and confirm that the sand–gravel deposits contain zones with a high percentage of gravel of a magmatic origin, which are characterized by higher electrical polarizability.
