Abstract

Abstract

The geophysical anomalies are very weak in mineral prospecting of the areas with thick covering layer, especially in the second exploration of crisis mines where the cultural disturbances are strong, which makes it more difficult for ore prospecting. In order to carry out the explorations for hidden ore deposits in coverage areas, we adopt three methods with artificial source, namely, transient electromagnetic method (TEM), controlled source audio-frequency magnetotelluric (CSAMT) and induced polarization (IP) respectively, whose signals are strong enough for prospecting in the working areas. In addition, we have analyzed the advantages of the combination of these three methods in theory. It is found that the three methods can not only complement with one another in depth but also correct one another in interpretation. The electrical joint interpretation method has achieved a satisfying result in metal prospecting in Gansu Province, where these three methods complement and validate each other well. Therefore, the electrical joint interpretation method provides an effective way for mineral exploration in coverage areas.
