| 摘 要： | 小伊诺盖沟金矿位于内蒙古呼伦贝尔盟额尔古纳市境内的额尔古纳河东岸.小伊诺盖沟金矿的发现是在额尔古纳地区寻找岩金矿的一大突破.笔者在小伊诺盖沟金矿区内发现了形成于中侏罗世的花岗斑岩，并确定该花岗斑岩为小伊诺盖沟金矿的容矿岩和含矿岩.小伊诺盖沟金矿矿体有蚀变花岗斑岩和脉状热液石英岩两种，以前者为主，前者分布于后者的两侧.小伊诺盖沟花岗斑岩的形成受控于额尔古纳河韧性剪切带，额尔古纳河韧性剪切带是小伊诺盖沟花岗斑岩的导岩构造，也是小伊诺盖沟金矿的导矿构造.额尔古纳河韧性剪切带形成过程中所产生的次生裂隙是小伊诺盖沟金矿的容矿构造.

| Abstract: | The authors discovered the Xiaoyinuogaigou granite porphyry in the southern margin of the Ergun block,where the Xiaoyinuogaigou gold deposit is located The research confirms that:1)the Xiaoyinuogaigou granite porphyry was formed in middle Jurassic;2)the ore bearing rock and the host rock of the Xiaoyinuogaigou gold deposit are the Xiaoyinuogaigou granite porphyry;3)the Xiaoyinuogaigou gold deposit is a mesothermal deposit;and 4)the Ergun ductile shear zone is the passageway for the Xiaoyinuogaigou granite porphyry,and the secondary fracture of the Ergun ductile shear zone is the host structure of the Xiaoyinuogaigou gold deposit |

| Keywords: | Xiaoyinuogaigou gold deposit granite porphyry ductile shear zone |
