摘要
梧南金矿床是产于碳酸盐岩地层的微细粒浸染型金矿类型。文章介绍了矿区地质背景、矿床地质特征,矿石、围岩的稀土配分曲线呈富轻稀土的右倾型,曲线形态基本一致。表明矿石对围岩的继承性,酸性斑岩也为成矿提供了一定的热源和部分含矿热液。石炭系碳酸盐岩成为金矿化的有利围岩,矿区构造运动使含金岩层进一步活化浸出、热液交代和迁移富集。
The Carlin-type gold deposit, Wunan gold deposit, was first found recently in carbonate rock stratum. According to the geological background and characteristics of the ore area, the paper distinguish that ore body exist in impurity carbonate rock. REE distribution patterns of the ore and wall rock are similar in right-dipping type abundant with LREE,showing ore-forming inheritance and acidic porphyry, the supplier of heat and parts of ore fluid. Carbonate rock of Carboniferous system become favorable wall rock for gold mineralization and later structure activity make ore materials mobilize for hydrothermal fluid replacement and enrichment.
