摘要
阿富汗某铜矿是目前世界上已发现和探明的特大型铜矿之一,分为中、西两个矿段。铜矿受地层控制明显,它产于上元古界洛伊赫瓦尔组内。以西矿段为研究对象,在前人工作的基础上,笔者根据野外实践,进一步论述了其矿床特征,对该矿床特征及成因进行了分析和总结,认为该矿床经历了沉积成矿、变质热液改造富集成矿、氧化作用三个成矿阶段,并得出沉积—变质改造型层控铜矿床的结论。
A Copper Project in Afghanistan,one of the most outsize copper mine that has been discovered and ascertained in the world,is divided into central and west part.Obviously it is controlled by stratum,the copper deposit originated in the Royhewaer Group.Taking west ore block as research objective,the author analyzes and summarizes the deposit characteristics and the genesis of the west deposit based on the previous study and our field practice.It concludes that this deposit has undergone 3 mineralization periods which are sedimentary mineralization,hydrothermal solution remoulding enrichment mineralization and oxidation.
