Prospecting effects and their significances of induced polarization and soil geochemical methods in Beiya area, northwestern Yunnan

In order to make a prospecting breakthrough in the peripheral areas of Beiya, a super large gold polymetallic deposit in the northwest of Yunnan, this paper carries out a comparative experimental study of IP and dual-frequency IP methods in the known typical orebodies. The results show that both methods can effectively reveal the distribution of known ore bodies, but IP has a stronger anti-interference ability and a higher deep resolution, so IP is more suitable for Beiya area. Soil’s geochemical data reveal that the high abundance of Pb and Zn in the soil of Beiya prospective area I has great interference on IP anomalies. The distribution range of orebody II in Beiya prospect area is revealed by using the combination of IP and soil’s geochemical method, which has achieved good application effect and provided an effective technical method combination for the exploration of the peripheral area of Beiya in the future.
