刚果(金)科卢韦齐铜矿地质特征及成矿机理浅析

摘要

The kolwezi copper deposit of DRC is located in the northwestern part of central Africa CongoZambia giant copper cobalt metallogenic belt which is the world's third-largest copper best. Orebodies occur in quartz dolostone, dolomitic schists and silicon shale. Through the analysis of regional geological background and ore deposit geological characteristics, it is found that the deposit formed in Proterozoic era, early controlled by strata, in medium-term modified by regional metamorphism and magma hydrotherm, finally superimposed by structural hydrotherm and secondary enrichment. The genetic copper deposit type is sedimentary metamorphic-hydrothermal superimposed and modified deposit.%刚果(金)科卢韦齐铜矿位于世界第三大铜矿带中非刚果(金)-赞比亚巨型铜钴成矿带的北西部.矿体赋存在加丹加岩系的罗安群R2矿山组石英质白云岩、白云质片岩及硅质页岩中.通过对区域地质背景、矿床地质特征等分析,认为矿床形成于新元古代,产于裂陷地槽中,矿床早期受地层控制,中期受区域变质及岩浆期后热液改造,晚期受构造热液叠加及次生富集,矿床成因类型为沉积变质-热液叠加改造型铜矿床.
