摘要
中非铜钴成矿带位于卢菲莲弧形构造带的东段,该铜钴成矿带已成为世界钴第一、铜第三金属原材料生产基地。马本德铜矿床位于中非铜钴成矿带的东部,研究该铜矿床具有重要的经济和现实意义。通过对马本德铜矿床在地层、构造、岩石蚀变等地质特征进行研究,在此基础上总结该矿床控矿因素,进而分析矿床成因。结果表明,马本德铜矿床受地层和构造因素共同控制。罗安群为矿源层,在后期变质作用和构造活动的影响下,成矿元素发生活化、迁移以及重新富集成矿,最后部分矿体在表生富集作用下形成表生矿体。
The Central African copper-cobalt metallogenic belt is located in the eastern section of Lufilian arc tectonic belt.The copper-cobalt metallogenic belt has become the first-largest cobalt and the third-largest copper metal raw material production base in the world.The Mabende copper deposit is located in the east of the Central African copper-cobalt metallogenic belt.It has great economic and practical significance to research this copper deposit.Based on the study of the geological characteristics of the Mabende copper deposit,such as strata,structure and rock alteration,the ore-controlling factors of the deposit are summarized,and the genesis of the deposit is analyzed.The results show that the Mabende copper deposit is jointly controlled by stratigraphic and structural factors.The Roan Group is the ore source layer and under the influence of metamorphism and tectonic activities,the ore-forming elements were activated,migrated and re-enriched.Supergene ore bodies formed under the action of supergene enrichment.
