The effects of applying high-power IP and CSAMT sounding to the exploration of deep concealed ore deposits

The exploration of deep concealed ore deposits is the main task at present. A lot of electrical measurements have been com-pleted in Xilin Gol League of Inner Mongolia in recent years, which mainly consist of high-power IP and CSAMT or their combinational methods, with good prospecting results achieved. High-power IP measurement was used for discovery and delineation of mineralization limits and distribution of structures in the ore district;Inversion of resistivity of CSAMT section was conducted to deduce underground electrical characteristics of lithology, geological structure, attitude of structure, and size and space of ore ( mineralized) body. The re-sults achieved by the authors provide the basis for the drilling. This paper describes the exploration process of a certain deep concealed lead-zinc deposit in Inner Mongolia and makes interpretation.
