The obtained results of the simulation were used to construct a three-dimensional model of the geoelectric region using a complex software developed by the authors. The model indicates that the subsoil of the region studied to a depth of 60 km, has got numerous conductivity heterogeneities. The depth of the roof, of the most reliably selected objects, occurs below 6 km. The most conductive parts of objects (with a resistance of less than 10 ohm m and the integral conductivity of more than 50 % of the total) are located at the depths of 20—40 km. The most conductive parts of anomalous objects are consistent with Smelyansk and Bobrinets fracture zones and with their cross-section with Golovanev suture zone. |
