Research of electrical characteristics and prospecting rules of gold deposit in Wanrendong area of Guizhou Province

In order to explore the regularity between Wanrendong gold deposit and geophysical electrical characteristics and expand thoughts for Wanrendong gold deposit prospecting, the authors comprehensively investigated the electrical structural characteristics of Wanrendong gold mine area, through the introduction of geological and physical characteristics of Wanrendong gold deposit, as well as the CSAMT (controlled source audio magnetotelluric method) basic theory and the transitivity measurement work. The spatial distribution characteristics of gold deposit-related geologic body, structure, and alteration was identified, and the prospecting geophysical rules of gold deposit were summarized in this paper. The gold deposit was mostly distributed in the geophysical low resistance anomaly areas, or transition areas between high resistance and low resistance. This method proved to be effective and dependable after later borehole certification. These achievements could provide geophysical exploration method of gold-prospecting for Wamrendong gold deposit area or similar areas.
