摘　　要：对碱泉子金矿床的矿床地质特征进行了较为系统的研究,在此基础上探讨了矿床的成因。研究结果表明,碱泉子金矿床矿区内的前震旦系变质岩体为含金石英脉的形成提供了重要的成矿物质和成矿流体,矿区内的褶皱和断裂构造为重要的导矿和容矿构造,碱泉子金矿床为复式成因的中温热液石英脉型金矿床。This paper studies the geological feature of Jianquanzi gold deposit,metallogenesis of Jianquanzi gold deposit are analysed in accordance with this feature.The results show that the pre-sinian metamorphic body in Jianquanzi gold deposit region provided important Ore-forming armamentariums and ore-forming fluids for gold-bearing quartz vein.Fault constructions and folds in the region are important lead ore and hold ore constructions.Jianquanzi gold deposit belongs to duplex causes mesothermal temperature gold-bearing quartz vein type of deposit.
