摘　　要：通过对二道沟金矿床矿物学的详细研究和对比,表明该矿床低温热液矿物组合和低温热液蚀变十分发育;与典型的冰长石- 绢云母型浅成热液金矿的矿物组合十分相似;其应属于与流纹熔岩及其火山碎屑岩密切相关的浅成热液型金矿床.The studies on mineral geochemical for Erdaogou gold deposit located in the west part of Liaoning province indicate that it is characterized by low temperature mineral association such as pyrite, chalcopyrite, galena, sphalenite, telectrum, quartz, seriate, calcite, adual etc. and well developed thermal alteration such as solidification, sericitization, chloritization, carbonation, kaolization and argilization. This mineral association is the same as those of adual sericite type epithermal gold deposit hosted volcanic rock. It is an epithermal gold deposit relating to volcanic rock.
