APPLICATION OF ELECTRICAL TOMOGRAPHY FOR THE STUDY OF NEAR-SURFACE GEOLOGICAL SECTION

Electrical tomography surveying can be successfully applied for the detailed study of the near- surface geological section. The approach and the basic elements of the methodology for data acquisition, processing and interpretation are revealed on the example of the performed electrical tomography surveying in the region of "Marichin valog" - a potential site for long-term storage of radioactive waste products. Field measurements are performed along 10 profiles. The distribution of the electrical resistivity along the profiles and the obtained zoning of the geoelectrical section are illustrated. Structural map of one well-distinguished geoelectrical boundary is achieved. The obtained results confirm the high geological efficiency of the electrical tomography surveying.
