摘　　要：刚果(金)科卢韦齐位于世界主要铜矿产地之一的中非赞比亚-刚果(金)铜矿带。为了对该区内KAM和KAS地表覆盖严重的矿权区铜钴矿资源开发及远景评价的地质工作提供探矿线索和工程依据,采用物探激发极化中间梯度法和地面高精度磁测法进行综合勘查研究。通过地面高精度磁法勘测圈定化极异常,有效为罗安群矿山组地层的划分提供了线索;通过激发极化法中间梯度测量圈定异常范围,进一步缩小找矿靶区,并为下一步地质工程布设提供了物探依据;通过对综合物探勘查的解译,得到KAS矿权的矿化地质条件远景不佳,建议谨慎投入,而KAM矿权可对所圈的异常靶区进行下一步探矿工程验证的结论。Kolwezi is located in the Zambia-Congo copper belt in Central Africa,one of the world's major copper producing areas.In order to provide prospecting clues and engineering basis for the exploita-tion and prospect evaluation of copper and cobalt ore resources in KAM and KAS with serious surface cover-age in this area,the geophysical stimulated polarization intermediate gradient method and high-precision surface magnetic survey method are used for comprehensive exploration.Through the high precision magnet-ic survey on the ground,the polar anomaly is delineated,which provides a clue for the geological classifica-tion of the Luoan Group mine formation.The anomaly range is delineated by the middle gradient measure-ment of the induced polarization method,and the prospecting target area is further reduced,and the geo-physical basis is provided for the next geological engineering layout.Based on the interpretation of the com-prehensive geophysical exploration,it is concluded that the mineralization geological conditions of the miner-al rights KAS are not promising,and it is recommended to invest cautiously,while the KAM mineral rights can carry out the next exploration engineering verification of the anomalous target area.
