摘　　要：色洛河群金银别组提供了主要成矿元素来源;青茶馆—白水滩断裂带为控矿构造,金银别组内层间滑动带为主要容矿构造;中侏罗世钾长花岗岩提供了热动力源及部分汽水热液。根据不同控矿因素的控矿作用及空间组合建立了以侵入岩→断裂带→矿源层热对流循环体系为基础的成矿模式,确定矿床成因类型为低硫化中浅成低温热液型,矿床遭受一定程度的剥蚀,层间滑动带深部及浪柴河背斜核部仍有找矿前景。Jinyinbie Formation of Shailuohe Group provided the main source of the metallogenic elements, the fault zone from Qingchaguan to Baishuitan was the ore-controlling structure, the interlayer sliding zone is the main host structure; the Middle Jurassic moyite must have provided thermodynamic source and vapor-water hydrothermal fluid. The metallogenic model is established based on the intrusive rocks→fault zones -→thermal convection circulation system of source bed according to controlling mineralization and space combination of different ore-controlling factors, It is confirmed that the genetic type of the deposit is a low sulfidation,medium shallow metallogenic and epithermal type, the deposit suffered a certain erosion, there is still the prospect of ore prospecting in the deep part of the interlayer sliding zone and the Langchaihe anticline core.
