本文介绍了纳米比亚罗雷铜钼矿区的地质特征,以及激发极化法在该区应用情况,说明通过激电中梯扫面获得的激电异常可以快速圈定找矿靶位,然后使用激电测深推测矿(化)体的埋深和产状,为地质探矿工程提供设计依据,也取得了激电测深二维反演方法的基础性成果,为罗雷铜矿深部和外围找矿指明了方向,同时也为今后在非洲地区开展电法找矿工作积累了宝贵的经验。
In the article, the geological characteristics and the application case of high power IP method to prospecting at Lorlei copper deposit is introduced. Based on the records of IP and Symmetrical Quadrupole Sounding, the distribution and the rough buried depth of the anomalous body characterized by mid to higher resistance and higher polarization are inferred in Lorlei prospect. According to the exploration datum of trenching and drilling, it's demonstrated that the anomaly of mid to higher resistance and higher polarization represents the mineralization body composed of copper,molybdenum,iron and other metal sulfide, which not only does it suggest direction of exploration in and around Lorlei prospect, but also provided valuable experiences for electrical prospecting on arid region in southern Africa.
