| 摘 要： | 湖南江溪垄金锑矿床赋存于新元古界板溪群五强溪组浅变质岩系中.成矿严格受NE向剪切断裂带控制.该矿系金锑共（伴）生矿床.矿体呈陡倾斜的交错脉状产出，沿走向、倾向变化均较稳定.金主要产于近矿蚀变围岩中，毒砂为金的重要载体矿物；锑的富集则与硅化关系密切.矿石为高砷含金锑矿石.以锑为主的选矿试验结果表明，主要回收对象为辉锑矿，并可综合回收金.

| Abstract: | The Beigangou gold deposit,located in the middle section of Yanshan metallogenic belt,belongs to quartz vein type in ductile shear zone.The Neoarchean metamorphic rock,which contains abundant gold,is the source bed for gold metallogenesis.Ductile shear zone controls the gold metallization,which can be divided into two stages.The gold metallization is related to the brittle deformation of the ductile shear zone.Natural gold occurs mainly in the microfissures,intergranular porosities or cavities of pyrite,chalcopyrite and their oxides.The wallrock alteration is intense,with mainly pyritization,silicification,sericitization,carbonation,albitization,chloritization,baritization etc.The exploration in the future should focus on quartz vein type and altered rock type of gold mineralization in No.1 fault belt and shear zone quartz vein type of gold mineralization in the tensional extended range of No.2 ductile shear zone in the east. |
