APPLICATION OF OMNIDIRECTIONAL INDUCED POLARIZATION LOGGING IN PROSPECTING OF GOLD DEPOSITS: A Case Study of Zhaoxian Area in Shandong Province

Compared with the ground induced polarization (IP) method, the well IP logging is much closer to orebody, and thus it has higher signal-to-noise ratio and exploration precision, which is widely used in the survey and exploration of metal minerals. Based on the application of the method in the prospecting of gold deposits in Zhaoxian area of Laizhou City, Shandong Province, the paper discusses the practical effects of IP logging in gold deposit exploration. The results show that the rocks with enriched gold and polymetallic ores are characterized by low resistivity, high polarizability, and distinct anomaly. The method can judge the distribution rule and state of orebody, and guide the drilling direction of mineralized body, with obvious geological effects.
