Deep structure of the Ingul megablock according to geoelectric researches

Abstract

On the basis of the magnetotelluric sounding and the magnetovariation profiling experimental data the analysis and interpretation using the software system of three-dimensional modeling of the low-frequency electromagnetic field, a series of the electric conductors from the surface to the depths of 2500 m, and from 5 to 30 km and from 50 to 120 km is revealed mainly in the central part of the Ingul megablock and within the Golovanivsk suture zone. The conductivity anomalies characterize separate parts of the Yemylivska, Pervomayska, and Zvenigorodsko-Bratska and Kirovogradska fault zones.
