| 摘 要： | 小佟家堡子金矿床产于辽河群大石桥组三段第四、五层之间的互层带和大石桥组三段五层与盖县组地层的接触面上。矿化类型为含金黑云变粒岩型、含金硅质岩型。矿体受层滑断层控制呈层状、似层状。地质特征和测试数据显示，容矿岩石黑云变粒岩、硅质岩是辽东裂谷中晚期海底火山－喷流作用形成的地质体。它既是矿源岩又是赋矿层，是经印支期重熔花岗岩热动力改造作用形成的中低温热液型金矿床。

| Abstract: | The Xiaotongjiapuzi gold deposit is hosted in Dashiqiao Formation of Liaohe Group. The types of mineralized rocks are fine grained biotite gneiss and silicalites. The strata form and quasi strata form ore bodies are controlled by strike slip faults. Based on the geology and chemical analysis, host rocks of fine grained biotite gneiss and silicalite were formed by seabottom volcanic eruption in middle late rifting period, which constituted ore source and ore hosting rocks. The evidence mentioned above indicates that it is a epithermal ore mesothermal deposit formed by thermodynamic reformation from remelting granite magmatism of Indosinia |
