| 摘 要： | 巴都希贾乌铜金矿是坐落在印度尼西亚松巴岛西南部的世界级的斑岩型铜金矿床,产于岛弧环境。从容矿岩石、矿化、蚀变、成矿流体等方面分析总结了该矿床的基本特征。矿床在岩浆组合、空间形态和矿化及围岩蚀变特征上均体现出了明确的斑岩型矿床的特征;矿区围岩蚀变可划分为四个阶段,与成矿关系最为密切的是第一阶段的黑云母化;成矿流体为相对低温高盐度的流体,且具有由深到浅石盐溶解温度升高的趋势。

| Abstract: | Batu Hijau is a world-class porphyry copper-gold deposit located in the southwest of Songba Island, Indonesia. It occurs in island arc environment. The basic characteristics of the deposit are analyzed and summarized in terms of host rocks, mineralization, alteration and ore-forming fluids. The characteristics of porphyry deposits are clearly reflected in magmatic assemblage, spatial morphology, mineralization and wall rock alteration. The wall rock alteration in the mining area can be divided into four stages, and the first stage of biotitization is the most closely related to mineralization. The ore-forming fluid is relatively low temperature and high salinity fluid, and has the trend of increasing the dissolution temperature from deep to shallow salt. |
