中文摘要: 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。通过研究矿床地质特征,分析地层、构造、岩浆岩对矿床的控制作用,认为哈西金矿的矿体主要赋存在石炭系太勒古拉组地层中,矿石中主要金属矿物有黄铁矿、毒砂、黄铜矿、磁黄铁矿、辉砷镍矿、自然金等;区内NE向主干断裂对金矿体的产出起到控制作用,EW向构造带与其交会地段是矿体的赋存部位;区内玄武岩与矿体关系密切,为含矿建造中金的活化、迁移、富集提供热动力。同时指出NE向主干断裂与EW向构造带交会地段及其旁侧中酸性脉岩分布区、黄铁矿化、毒砂化、硅化蚀变较发育区、Au异常浓度>200ppb分带区,应作为下一步重点找矿方向。

Abstract:Haxi gold deposit is a recently discovered gold deposit with great metallogenic potential, which is located in the southwest of Hatu gold deposit in the Tuoli county, XinJiang. We consider that the orebodies are found in the Carboniferous of Telegula Fm by studying the geological characteristics of deposit, and analyses the controlling effect of stratum, structure, magmatic rocks. The mainly ore minerals are pyrite, arsenopyrite, chalcopyrite, gersdorffite, pyrrhotite and native gold. The structure role of NE-trending is ore-controlling by gold orebodies, and rich orebody always occyrs in the zones where EW and NE-trending fractures intersect. Basalt in this area is closely related to ore body, it provides thermal power for activation, migration and enrichment of gold in ore-bearing construction. We also pointed out that this areas can be as the focus of next prospecting, where EW and NE-trending fractures intersect, distribution area of the lateral medium-acidic dyke, relatively developed areas of pyritic arsenopyrite silicification alteration, zoning area of anomaly concentration of Au>200ppb.
