The application of the dual-frequency induced polarization method to the prospecting and appraisal of molybdenum deposits in Henan Province

Abstract：This paper mainly deals with the process of using dual-frequency induced polarization in rapid exploration of the mountain area of western Henan Province with the purpose of finding ore bodies and the problems worthy of attention in the field engineering. Through dual -frequency?induced polarization intermediate gradient survey, three induced polarization anomalies in the working area was discovered. An integrated analysis of the induced polarization anomalies was also made on the basis of local geological data, physical properties of rocks and geochemical secondary halos. Drilling has proved that the anomalies are related to concealed molybdenum ore bodies and molybdenum mineralization. It is also proved that dual-band induced polarization can be fully adapted to the rapid exploration and evaluation of the mountain area of western Henan Province with good results achieved.
