摘要
阜新水泉沟金矿点位于辽西大巴-瓦子峪-后三角韧性剪切带内,矿体赋存于断裂带中,呈脉状、似层状、透镜状产出,围岩蚀变主要有硅化、绿泥石化、高岭土化及绢云母化等,其中硅化与金矿化关系密切。水泉沟金矿的成矿物质来源于太古宇建平群大营子组,多阶段、多期次的构造活动促使地层中金活化,含矿流体随着岩浆沿着构造裂隙迁移,最后在有利部位富集成矿,矿床类型为韧性剪切带石英脉型-蚀变岩型金矿。
Shuiquangou gold deposit in Fuxin is located in the Daba-Waziyu-Housanjiao ductile shear zone in the west of Liaoning Province.The ore bodyarehosted in the fault zone,and occur as vein,vein-like and lenticular type.Thewall rockalterations are mainly composed of silicification,chloritization,kaolinization and sericitization,in which the silicification is closely associated with gold mineralization.The ore-forming material of Shuiquangou gold deposit comes from dayingzi formation of Archean jianping group.The multi-stage tectonic activities promote the activation of gold in the stratum.The ore-bearing fluid migrates along the structural fracture with magma,and finally enriches in the favorable position.The deposit type is quartz vein altered rock type gold deposit in the ductile shear zone.
