| 摘 要： | 线金厂金矿床是一热液充填型小型金矿。其矿化过程可以划分为4个阶段:①大石英脉形成阶段(伴有少量黄铁矿);②铅锌铜多金属硫化物形成阶段;③以细粒方铅矿为主的金属硫化物阶段;④方解石细脉形成阶段。金矿化主要发生在第二和第三矿化阶段,金与金属硫化物密切共生。矿石中金以自然金和银金矿两种形式存在,仅有少量以类质同象形式存在于金属硫化物中,矿石中的金矿物主要充填于矿物裂隙中和嵌布于矿物晶粒之间,少量被包裹在矿物之中。

| Abstract: | Xianjinchang gold deposit is of small-scale hydrothermal filling type.Its mineralization process can be divided into 4 stages:(1) the formation of major quartz vein(associated with a little pyrites):(2)the mineralization of Pb-Zn-Cu pollymetal sulphides:(3)the mineralization of metal sulphides,mainly fine-grained galena:(4)the formation of calcite veinlets.The gold mineralization mainly occured in the second and third stages,and gold is closely paragenetic with metal sulphide filling in the cracks or intervals of mineral grains,locally included in a mineral grain,in the form of native gold,electrum and a little with isomorph. |
