刚果(金)加丹加省卡拉比铜钴矿床地质特征及外围找矿方向

Geological characteristics and peripheral prospecting direction of kalabi copper cobalt deposit in Katanga Province,Congo (DRC)

卡拉比矿区位于中非铜钴成矿带刚果(金)段中部,矿区从1923至1951年期间连续进行规模工业化开采,采出铜矿石平均品位在10%以上,是刚果(金)利卡西地区较早开采的矿山之一。现在地表形成了长约320m,宽约35m~145m,深约40m的充水采坑。笔者通过对矿区矿床地质特征进行总结、分析,为该矿区下一步找矿工作指明方向。

Kalabi mining area is located in central Congo (DRC) section of The Copper-cobalt metallogenic belt in Central Africa.The mining area has been continuously industrialized from 1923 to 1951,and the average grade of copper ore produced is above 10%.It is one of the earlier mines in Likasi region of Congo (DRC).At present,the surface has formed a water-filled mining pit about 320m long,35m~145m wide and 40m deep.By summarizing and analyzing the geological characteristics of the deposit,the author points out the direction for the next prospecting work in the mining area.
