刚果(金)DIMMA铜钴矿床地质特征及成因分析

摘要

DIMMA铜钴矿区位于著名的刚果(金)—赞比亚卢菲利褶皱弧铜钴矿带的北西端.DIMMA铜钴矿床的形成与成岩期的火山活动、同生断裂活动有关,并受后期造山过程中的褶皱、断裂和变质作用的改造和次生富集,形成多成因多重控制的铜钴矿床.%Dimma Cu-Co deposit is located in the northwest end of Cu-Co ore belt in Luffilian fold arc at boundary between Congo(Kinshasa) and Zambia. It is related to volcanism and syn-sedimentary faulting and reworked by folding ,fracturing, metamorphism and secondary enrichment in late orogenic process. . Therefore, it is a polygenous Cu-Co deposit controlled by multi-factors.
