摘要
在贵州威宁县大菁脚铅锌矿勘查中,通过激电中梯和激电测深,圈定了5个强度较小的高极化低阻异常,推断1#、2#和3#为铅锌矿致异常,对2#异常钻探验证认为,因地形高差较大影响激电异常推断的准确性,采用瞬变电磁法进一步确定了异常体的空间位置,在1#高极化率高二次电位低阻复合部位推测见矿,达到了电法组合使用,提高解释推断准确性的效果,值得下一步找矿参考借鉴。
In the lead-zinc exploration of Daqingjiao, by Induced electric-medium gradient method and in- duced polarization sounding, 5 high polarization and low resistance abnormities of weak intensity are deter- mined, it＇s inferred 1#,2# and 3# are lead-zinc abnormities, the drilling teat of 2# abnormity thought that the big level difference influenced the accuracy of induced abnormal inference, so the spatial position of abnormity is ensured by TEM,the ore was found in the low resistance composite part of 1# high polarization and high sec- ondary potential, the effect of electrical methods combined utilization and increase the inference accuracy are a- chieved, it＇ s worth to be learn for future exploration.
