摘　　要：EH-4连续电导率成像系统作为新一代电磁观测系统,能够观测到离地表几米至1000m(更深)内的地质断面的电性变化信息。文章介绍了EH-4连续电导率成像系统工作原理、野外工作方法和数据处理。通过EH-4连续电导率成像系统在小于赞金矿和阿尔恰勒铅锌矿中的实际应用效果,说明EH-4连续电导率成像系统能较准确反映构造、矿脉及围岩等的空间展布特征,具有较高的勘探精度和较大的勘探深度,且轻便快速,应在金属矿勘探中推广。EH-4 magnetotelluric image system is a unique instrument used for measuring the electrical resistivity of the earth over depth ranges of a few meters to more than one kilometer.This paper introduced principles,field operation, data processing of EH4 magnetotelluric image system. EH-4 magnetotelluric image system had been applied in Xiaoyuzan gold Deposit and Aerqiale Lead-Zinc Deposit.And the results indicated that EH-4 magnetotelluric image system can effectively in mineral exploration.
