摘要

Formation of orebodies and, especially, preservation of orebodies has close correlation with geological structure. It is obvious that orebodies are controlled by geological structures in the target area. In order to find out character of geological structures, divide different geological bodies, and distinguish possible orebodies,DDS-3 VLF-EM instrument combined with high prices GPS survey is used. One anomaly of possible orebody had been discovered. The anomaly has 30-50meters wide, and 200 meters long with discontinuous extension. It is indicated that application of VLF-EM is efficient to realize distributed characters of orebodies and fault structures in the investigation area, and also can provide preliminary basis for nest step research and prospecting works.
