摘要

The Kolwezi copper deposit of DRC is located in the northwestern part of central Africa Congo-Zambia 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.
