摘　　要：西藏谢通门县雄村铜（金）矿是新发现的超大型细脉浸染型铜（金）矿。通过详细的岩石学、矿石学研究，表明矿石类型主要分为氧化矿石、次生硫化物矿石和细脉浸染状硫化物矿石三大类型。矿石主要为细脉浸染状。主要金属矿物为黄铜矿、黄铁矿、磁铁矿、磁黄铁矿，其次是辉铜矿等。主要非金属矿物为石英，约占矿物总量的60％～70％；其次是红柱石、钾长石、斜长石、黑云母、白云母、绢云母、绿帘石、石榴子石等。矿石主成矿元素以Cu为主，伴生有用组分为Au，Ag，Zn和Pb等。The Xiongcun Cu（Au） deposit is an ultra-large Cu（Au） deposit and an epithermal low grade impregnation deposit. The detailed study on lithology, ore minerals and authentication of almost 400 pieces of polished sections and thin sections, and systemic documantation of drills can help to discuss ore type and composition, etc. There are three types of ore, that is, oxidation ore, secondary sulfide ore and low grade impregnation ore. Cu is the most main component and the useful accompanying elements are Au, Ag, Zn, Pb, etc. The dominant metallic minerals are chalcopyrite, pyrite, magnetite, pyrrhotite and the subordinate metallic mineral is chalcocite. The dominant non-metallic mineral are quartz. It accounts for about 60-70% of the all minerals. The subordinate non-metallic minerals are andalusite, feldspar, plagioclase, biotite, muscovite, sericite, epidote, garnet and so on. In this paper, the ore characteristics of the Xiongcun Cu（Au） deposit are dwelt on in terms of the mineral composition, chemical constitution, and structural formation.
