摘　　要：大功率IP是目前地球物理探测最常用的方法之一,以岩(矿)石、水的激发极化效应的差异为物性前提,采用合理的装置形式,研究地下地质体的极化效应的变化。运用激电测深可以有效地查明异常体埋深、规模及控矿构造的深部发育情况。本文以某地铅锌矿激电测深为例,通过在不同标高进行水平切片得到平面激电资料,并结合激电剖面图有效地提高勘探精度。High-power IP is a common geophysical exploration method based on the difference of induced polarization effect between rock(ore)and water.Reasonable device is adopted to study the change of polarization effect of underground geological bodies.IP sounding can effectively find out the buried depth and size of abnormal bodies and development of ore-controlling structures to depth.This paper deals with IP sounding exploration in a Pn-Zn deposit.Plane IP data are obtained by horizontally slicing the deposit at different elevation.Combination of the data and the IP profile improves the exploration accuracy effectively.
