摘要
索尔巴斯陶金矿床位于博格达晚古生代弧后盆地和哈尔里克古生代复合岛弧结合部位,矿体呈脉状产于下石炭统塔克尔巴斯陶组中,主要由石英脉型和蚀变岩型矿体组成。蚀变岩型矿体发育强黄铁矿化、硅化和绢云母化,成矿作用主要分3个阶段:石英-硫化物阶段(I)、含金石英脉-硫化物阶段(II)和含金多金属硫化物阶段(III),其中II、III阶段为金主要成矿阶段。电子探针分析结果表明,索尔巴斯陶金矿含金矿物主要为黄铁矿和石英,以自然金为主,平均成色811.2,呈裂隙金、包裹金、粒间金形式分布。
Suoerbasitao gold deposit is located in the bind site between Bogda late Paleozoic back-arc basin and Harlik Paleozoic composite island arc,in Xinjiang.The orebody produced in the Takebasitao formation of Lower Carboniferous as veins,and it mainly composed of quartz vein and altered rock type.Altered rock was intensely development with pyrite ore,silicification and sericite alteration.Mineralization can be divided into three phases：Quartz-sulfide stage （Ⅰ）, Bearing quartz veins-sulfide stage （Ⅱ）,Gold-bearing polymetallic sulfide stage （Ⅲ）,of which Ⅱ,Ⅲstage is the main gold mineralization stage.Meanwhile electron microprobe analysis showed that Gold minerals of Suoerbasitao gold deposit are mainly pyrite and quartz with native gold, and its average fineness is 811.2,which was fractured gold,wrapped gold,and inter-particle gold in the form of distribution.
