Abstract

The results of geophysical works in different areas of Bazovskoe deposit are given. The study tested possibilities of high accurate magnetic prospecting, electric prospecting by median gradient and transient electromagnetic sounding when identifying and tracing ore-controlling structures, studying geological structure of the deposit. The analysis of the geophysical materials showed that methods of electric prospecting were the most informative. Transient electromagnetic sounding allows obtaining volume information on deep geologic structure of the studied object in bad grounding conditions. Three-layer structure of geoelectrical section of the deposit is identified according to transient electromagnetic sounding data. Magnetometry in combination with electric prospecting data makes possible to geologically interpret geophysical information with greater reliability. It is determined that, ore-controlling structures in electric fields are manifested by extended linear anomalies of decreased and increased conductivity, that is connected with mineralization features. In magnetic field, mineralized zones of crush are manifested, mainly, by negative linear anomalies.
