| 摘 要： | 哈图金矿由石英脉型和蚀变岩型矿体组成,蚀变岩型矿体遭受了强烈黄铁矿化、毒砂化、碳酸盐化、硅化和绢云母化蚀变.成矿作用划分5个阶段:钠长石-石英阶段(I)、黄铁矿-碳酸盐-石英阶段(II)、黝铜矿-黄铜矿-自然金阶段(III)、毒砂-碳酸盐-绢云母阶段(IV)和方解石-石英阶段(V).其中,II—IV阶段是主要金成矿阶段.哈图金矿含金矿物主要为自然金,平均成色912.自然金呈裂隙金、包裹金、粒间金形式嵌布在黄铁矿和毒砂中.当载金矿物为黄铁矿时,自然金与黝铜矿-黄铜矿-闪锌矿关系密切;当载金矿物为毒砂时,自然金与黄铁矿-黄铜矿关系密切.

| Abstract: | The Hatu gold deposit,locating in west Junggar of Xinjiang,is composed of quartz vein type orebody and alteration type orebody.The orebodies are hosting in tuff and basalt in Lower Carboniferous volcano-sedimentary rocks.We study the alteration-type orebody which mainly locates in the deep part of Hatu mine.Pyritization,arsenopyritization,carbonation,sericitization and chloritization are widespread in the alteration-type orebody.The ore-forming process of alteration-type orebody can be divided into five sta... |
