    Exploration of Erdaohe Silver Polymetallic Deposit in Inner Mongolia based on Induced Polarization Method by Baoyou Li, Zhiqing Shi, Zhiguang Yang, Lan Xu, Hanlie Cheng, David Sturdivant

    Published 2022-01-01
    “…In order to prove the feasibility of the deep application of this method, the high-power induced polarization sounding experiment with different devices and different power supply cycles was carried out in Erdaohe copper-silver lead-zinc mine. The test results show that by adopting the measurement method of the encrypted equipotential device and selecting the appropriate polar distance, when the power supply period is 32 s, the time delay is 200 s and the sampling width is 200 s, a good deep lead-zinc mine anomaly can be found. …”
