摘　　要：结合区域成矿地质背景,以KIMPE铜钴矿地质勘查成果资料为依据,对矿区地层、构造、矿体特征、矿石特征等进行了论述,并对矿床成因进行了分析。结果表明,KIMPE铜钴矿矿床受地层和断裂控制,新元古代加丹加系罗安群地层为初始矿源层。成岩成矿期后,卢菲利造山运动过程中的构造活动和变质作用对矿床进行了改造,使成矿元素发生活化、迁移和重新富集。此外近地表环境下的表生富集作用,导致了表生矿体的形成。KIMPE铜钴矿矿床成因类型属于沉积—热液改造型。According to the regional setting of geology and mineralization, combined with the geological exploration information of KIMPE Copper-Cobalt Deposit, the stratum, structure, ore body feature, ore characteristics and deposit genesis are discussed in this paper. The results show that, KIMPE Copper-Cobalt Deposit is controlled by strata and fracture, Roan group of Neoproterozoic Katanga system is the initial source of metal. The deposit was transformed by post-metallogenic tectogenesis and metamorphism during Lufilian orogeny, which led to activation, migration and re-enrichment of metallogenic elements. In addition, the near-surface environment of supergene enrichment led to the formation of supergene ore body. KIMPE Copper-Cobalt Deposit should belong to the sedimentary-hydrothermal reformed deposit.
