摘　　要：甚低频测量（VLF）、连续电导率成像（EH4）和激发极化法（IP）等高精度的地球物理探测技术在寻找隐伏矿的过程中发挥了重要作用.本文介绍了这些技术方法的原理、特点等,并结合具体的地质背景,阐述了这些方法结合在赵家围子银铅锌多金属矿床勘查中的应用.实践结果表明,赵家围子矿区深部存在明显的地球物理异常,异常强大、清晰,各种方法相互映证,展示了该矿床深部具有良好的成矿前景.VLF,EH4 and IP geophysical systems belong to electromagnetic survey methods with playing very good roles in forecasting concealed ore body.This paper introduces the different principle and character of the different technology methods,and also combines the pertinence geology background to indicate the application of the methods in combination to the exploration of Ag,Pb and Zn deposit in Zhaojiaweizi region.Practice shows that there is a clear geophysical anomaly in depth of the Zhaojiaweizi deposit.The anomaly is strong and in evidence,and all methods corroborate and complement each other.It is indicated that the Zhaojiaweizi deposit has a good metallogenic prospects and might become a big type exploration target for Ag-Pb-Zn deposit.
