| 摘 要： | 非洲已成为我国企业海外铜矿资源开发的投资主要目的地之一,针对非洲赞比亚铜矿山的深边部地质找矿技术问题开展的EH4物探找矿技术试验性应用研究,具有重要的示范效应.使用EH4连续电导率剖面测量仪完成的物探剖面测量所获取的某铜矿西矿区14线和东南矿区59线物探电性断面图,较好地反映了加丹加沉积盆地基底构造层与盆地沉积构造层之间的角度不整合沉积接触界面的空间形态展布,而且在含铜页岩层底板与基底构造层顶板之间的石英岩层与高阻异常具有较好的对应关系.这些地球物理信息可为赞比亚沉积岩型铜矿床的深部找矿提供十分重要的间接找矿线索.

| Abstract: | Africa has been one of the main overseas investment destinations of our country enterprise for cop-per resources development.For the geological prospecting technical problems in the outer and deeper areas of Zambia copper mines,the application experiment research of EH4 geophysical prospecting technique has an important demonstration effect.We measured the geophysical prospecting electrical profiles of line 14 in western mining area and line 59 in southeastern mining area for a certain copper mine by EH4 continuous conductivity section measuring instrument.These profiles expressed the space distribution between basement tectonic layers and sediment tectonic layers in Katanga Basin.We measured the geophysical prospecting elec-trical profiles of line14 in western mining area and line 59 in southeastern mining area for a certain copper mine by EH4 continuous conductivity section measuring instrument.These profiles expressed the space dis-tribution between basement tectonic layers and sediment tectonic layers in Katanga Basin.The geophysical information has provided important indirect prospecting clues for deeper areas of sediment-hosted copper de-posits in Zambia. |
