摘　　要：三合屯金矿区发育NE向韧性剪切带,由碎裂花岗岩、糜棱岩化花岗岩、花岗质糜棱岩、超糜棱岩组成。金矿体顺糜棱叶理分布在韧性剪切带内,早中侏罗世的韧性剪切作用形成金的初始矿源层。主金矿体形成于韧性剪切作用之后,与早白垩世火山岩浆活动有关,受叠加在韧性剪切带之上的脆性断裂控制,金矿体的形成是多阶段成矿作用的结果。NE ductile shear zone is developed in Sanhetun gold deposit,which consists of fragmentation granite,mylonitization granite,granitic mylonite and super-mylonite.Gold ore bodies are distributed along mylonite foliation in ductile shear zone.The initial ore-source stratum is formed by ductile shear function in EarlyMiddle Jurassic.The main gold bodies are formed after the ductile shearing and related to the Early Cretaceous volcano-magma activity.They are controlled by brittle faluts,which are superimposed on the ductile shear zone.The gold deposit formation is the result of multi-stage mineralization.
