刚果(金)KANUNKA铜钴矿床地质特征及远景浅析

Geological Characteristics and Prospect Analysis of KANUNKA Copper-cobalt Deposit in Congo(DRC)

通过对刚果(金)KANUNKA铜钴矿床的地层、构造、物探异常、矿体特征、矿石类型等成矿地质条件进行分析,认为本区的含矿地层为罗安群,导矿和容矿构造清晰,磁法异常显示了矿区的构造格架,电法异常与已知的矿化位置吻合,民采遗迹丰富。各种找矿标志明显,具有较好的找矿远景。矿床受地层和断裂控制,罗安群地层先后经历了沉积阶段、热液改造阶段、表生富集阶段3个成矿阶段,成因类型属于沉积—改造—次生富集型层状铜钴矿床。

Through the analysis of the ore-forming geological conditions such as strata,structure,geophysical anomalies,ore body characteristics and ore types of the KANUNKA copper-cobalt deposit in Congo(DRC),it is considered that the ore-bearing strata in this area are Luoan group,and the ore-con⁃ducting and ore-bearing structures are clear.The magnetic anomaly shows the structural framework of the mining area,the electrical anomaly is consistent with the known mineralization location,and the folk min⁃ing remains are abundant.Various prospecting indicators are obvious and have good prospecting prospects.The deposit is controlled by strata and faults.The Luoan group strata have experienced three mineralization stages:sedimentary stage,hydrothermal transformation stage and supergene enrichment stage.The genetic type belongs to the sedimentary-transformation-secondary enrichment layered copper-cobalt deposit.
