| 摘 要： | 红柳沟金矿床属中-低温热液构造破碎蚀变岩型金矿床,目前该矿床已经资源枯竭。为了更好地开展该矿床今后的找矿工作,综合分析了红柳沟金矿床的矿区地质特征、金矿体展布规律及找矿标志;并根据矿体特征、矿石质量、矿石矿物的生成顺序与形成阶段、金的赋存状态及围岩蚀变特征,简要地分析了矿床成因。研究认为,红柳沟金矿床的矿体受SN向的次级断裂构造控制,空间上具有向南侧伏现象,结合化探异常,加强沟南构造破碎蚀变带的深部找矿,将会大幅度提升该矿的远景储量。

| Abstract: | The Hongliugou gold deposit is a mesothermal to epithermal fractured fault-altered rock type gold deposit which was exhausted now.In order to carry out prospecting work in the area in future a comprehensive analysis was done on the ore field geological characteristics,gold orebody distribution regularities and ore prospecting indicators and the ore genesis was analyzed briefly according to orebody characteristics,ore quality and ore and mineral occurring sequence and forming stages,gold hosting state and country rock alteration characteristics.It is considered that the orebodies of the Hongliugou gold deposit were controlled by secondary SN trending fractures dipping towards south in space and the ore prospecting should be focused on the deep part of the fractured fault-alteration zone combined with geochemical anomalies.The prospective reserves of the deposit are expected to increase considerably. |
