内蒙古自治区鄂伦春旗奇力滨林场铅锌矿瞬变电磁法特征

Transient electromagnetic methods features of lead-zinc deposit of Qilibin forest farm in Oroqen Banner, Inner Mongolia

本文介绍了在内蒙古自治区鄂伦春旗奇力滨林场地区应用瞬变电磁法(TEM)寻找铅锌矿。采用800m×800 m发射框,点距20 m,这样能反映400 m以上的地下地电结构。根据不同地层视电阻率来确定异常,以达到寻找铅、锌、的目的。通过工程实例证实:在该地区,采用瞬变电磁法寻找铅、锌、金属效果显著。

In this paper, the authors introduce the application of transient electromagnetic methods（TEM） on lead-zinc ore of Qilibin forest farm in Oroqen Banner, Inner Mongolia. Using 800m×800m emission rim, spacing of 20 m, which reflects the geoelectric structure 400 m deep from the surface. Determined the abnormal according to the apparent resistivity of different stratum, to find lead and zinc ores. Prospecting examples confirmed that the TEM was used to find lead, zinc and metal ores in this area.
