尕尔穷铜金矿床为班公湖—怒江成矿带西段中重要的矽卡岩型矿床。通过显微镜下观察、扫描电镜能谱测试、电子探针成分分析测试,研究了矿石中Au-Ag有用组分及矿物共生组合特征,表明Au-Ag主要以互化物形式赋存于金属氧化物、硫化物及脉石矿物中,粒度介于显微细粒—微粒之间,赋存形式以粒间金和包体金为主,并判断Au-Ag互化物形成温度跨度较大,形成温度较高。1成矿地质背景班公湖—怒江成矿带属喜马拉雅巨型成矿带,
The Gaerqin copper-gold deposit is an important skarn type deposit in the west section of the Bangong Lake-Nujiang metallogenic belt. The microscopic observation, scanning electron microscopy (SEM) spectroscopy and electron probe compositional analysis were used to study the characteristics of Au-Ag useful components and mineral assemblages in ore, which indicated that Au-Ag mainly occured in the form of intermetallic compounds in metal oxides, Sulfides and gangue minerals, the particle size is between the microscopic fine particles - particles, the occurrence of intergranular gold and gold-based inclusions, and determine the formation of Au-Ag intermetallics span a larger temperature, the formation of temperature high. 1 Metallogenic Geological Background The Bangong Lake-Nujiang metallogenic belt belongs to the Himalayan giant metallogenic belt,
