Geological Features and Genesis of the Suoerbasitao Gold Deposit in Balikun, Xinjiang

摘要: 新疆巴里坤索尔巴斯陶金矿床位于博格达晚古生代裂陷盆地中，其矿床成因及成矿机制一直存在争论。笔者通过野外调查，发现索尔巴斯陶金矿床发育于石炭纪火山盆地边缘，受石炭纪火山机构中的短轴背斜控矿。综合资料分析认为，索尔巴斯陶金矿床受海相火山机构、短轴背斜、断裂构造控制，具成矿温度低、深度浅、含盐度小，成矿流体以大气水与岩浆水混和为主，矿区无浅成低温热液矿床典型矿物组合，成矿热液为二叠纪并非石炭纪成岩时的火山热液等特征。索尔巴斯陶金矿床成矿类型为类浅成低温热液型金-银矿床，该矿床类型的确定对下一步区域地质找矿具有重要的指导意义。

Abstract: The Suoerbasitao gold deposit is located in the Bogda late Paleozoic rift basin in Balikun, Xinjiang, and its genesis and ore-forming mechanism are still in dispute. Through carrying out field study, it's found that the Suoerbasitao gold deposit was developed at the edge of the Carboniferous volcanic basin and was controlled by the short axis anticline of the Carboniferous volcano. Furthermore, according to the comprehensive analysis, it's concluded that the Suoerbasitao gold deposit was controlled by Marine volcano, short axis anticline and fault structure. The Suoerbasitao gold deposit has the characteristics of low ore-forming temperature, shallow depth and low salinity. Besides, the ore-forming fluid of this deposit is mainly mixed by meteoric water and magmatic water. No typical mineral assemblage of epithermal deposit exists in this mining area. The ore-forming hydrothermal of this deposit is Permian volcanic hydrothermal, but not the diagenetic hydrothermal of the Carboniferous. Therefore, it's believed that the Suoerbasitao gold deposit is a gold-silver deposit, with the ore-forming type of epithermal deposit-like, which has a great guiding role for further geological prospecting to confirm the ore-forming type of this deposit. -
