| 摘 要： | 根据已知地质资料，某铅锌矿内褶皱不发育，构造以断裂为主，矿体主要受断裂构造控制。为探测该铅锌矿隐伏—半隐伏多金属矿化体，在勘探区内首先采用激电中梯方法进行地质扫面，寻找电阻率变化较大、极化率相对较高区域，快速查找并圈定激电异常区域；然后在取得的激电异常区域布设激电测深点，了解极化体的埋深及空间赋存状态。通过分析测量结果，认为两种方式所得的异常结果基本吻合，说明在寻找铅锌矿预查勘探中利用激电中梯扫面快速发现并圈定激电异常、利用激电测深了解极化体的埋深及空间赋存状态，能够取得较好的找矿效果，为指导工程验证提供了充分依据。

| Abstract: | According to the known geological data，the fold is not developed in a lead-zinc mine，the structure is mainly faulted，and the orebody is mainly controlled by faulted structure.In order to detect the concealed and semi-concealed polymetallic mineralized body in the lead-zinc mine，the IP intermediate gradient method was firstly used to carry out geological scanning in the exploration area to find the region with great resistivity variation and relatively high polarizability，so as to quickly find and delineate the abnormal region of IP.Then IP sounding points are laid in the obtained IP anomaly area to understand the buried depth and spatial occurrence state of polarized bodies.By analyzing the measuring results of the two ways of abnormal results are basically consistent，that in looking for the exploration of lead-zinc mine study using IP intermediate gradient scanned quickly found and delineating the IP anomaly，use the IP sounding to understand polarization body buried depth and spatial occurrence state，can achieve good prospecting results and provide a sufficient basis for guiding engineering verification. |
