新疆西准噶尔哈西金矿矿石矿物特征及金赋存状态研究
|
摘要
哈西金矿位于新疆托里县哈图金矿的西南部,是近期发现的一个具有较大成矿潜力的金矿。矿体受北东向安齐断裂控制,长短不一,厚度为0. 10～3. 42 m,Au品位为0. 17～64. 60 g/t,主要赋存在石炭系太勒古拉组中,且与玄武岩关系密切。原生矿石可分为蚀变岩型及石英脉型两种,矿石矿物主要有黄铁矿、毒砂、黄铜矿、辉砷镍矿和自然金等。根据矿物共生组合规律,可将金矿形成的过程划分为2个成矿期次(热液期、表生期)和4个成矿阶段(石英-硫化物阶段、石英-硫化物-自然金阶段、碳酸盐阶段、氧化阶段)。自然金主要赋存形式为裂隙金、包裹金和粒间金,其成色平均为954. 19‰,粒径主要集中在20～50μm之间,属于显微金。
Located in the southwest of the Hatu gold deposit in Tuoli County of Xinjiang, the Haxi gold deposit is a relatively large metallogenic potential deposit discovered in recent years. The orebody is controlled by the NE-trending Anqi fault and its thickness is 0. 10 ～ 3. 42 m, with gold grade being 0. 17 ～ 64. 60 g/t. It mainly occurs in the strata of Carboniferous Telegula Formation and is closely related to basalt. The primary ore of the Haxi gold deposit is divided into two types: altered rock type and quartz vein type. The main ore minerals include pyrite, arsenopyrite,chalcopyrite, gersdorffite, pyrrhotite and native gold. According to the mineral assemblage, the metallogenic process can be divided into two periods, i. e., hydrothermal period and supergene period, and four stages, namely, quartzsulfide stage, quartz-sulfide-native gold stage, carbonate stage, and oxidation stage. The modes of occurrence of native gold are mainly fissure gold, inclusion gold and intergranular gold with an average gold content of 954. 19‰.The particle sizes of native gold are mainly concentrated in 20 ～ 50 μm, thus belonging to the microscopic gold.
