| 摘 要： | 马攸木金矿床是西藏近年发现的首例规模较大、矿石品位富、金成色高的岩金矿床.作者通过对马攸木金矿床矿石组构、矿石共生组合及矿物特征研究发现,金银互化物主要有自然金、含银自然金、银金矿、自然银.载金矿物为黝铜矿、针铁矿、脆硫锑铅矿及石英;金银互化物的赋存形式主要为包裹体金、裂隙金及粒间金.金银互化物的形成、富集与热液成矿作用及表生风化作用关系密切.

| Abstract: | Mayoumu gold deposit is the first magmatic gold ore deposit in Tibet with larger scale,rich grade and high quality.According to ore texture,ore para-generation and mineral characters,Au-Ag compounds include native gold,electrum and native silver.Gold-bearing minerals are tetrahedrite,goethite,jamesonite and quartz.Occurrence of Au-Ag compounds are mainly inclusion,fracture and intergranular gold.The formation of Au-Ag compound is related with hydrothermal mineralization and weathering effect. |
