Application of Induced Polarization Method in Mineral Resource Exploration

Abstract

The search for hidden minerals with a large, buried depth depends on the guidance of geological and metallogenic theory, but it is difficult to master the geological characteristics of deep deposits. In this paper, taking a survey area as an example, the stimulated polarization geophysical method is used to obtain the information of deep minerals indirectly. Through the analysis and study of IP (induced polarization) anomaly and its characteristics in a tin polymetallic mining area, we delineate the IP anomaly distribution zone of metal ore, identify the distribution of polarized abnormal bodies by IP sounding, and determine the distribution of metallogenic fracture zones in the working area. Through the least square inversion of resistivity and polarizability, the spatial correspondence between the abnormal area of resistivity and polarizability and the location of ore bodies are obtained. The strategy of deep-mineral-induced polarization analysis adopted by us can provide a reliable geophysical basis for rapid deep geological prospecting.
