摘　　要：大瓮泉沟金多金属矿矿区主要出露地层为有二叠系中统大河深组、范家屯组。本区断裂构造较为发育,区域上北东向超壳深大断裂构造—敦化~密山断裂从区内通过,总体走向60°,在本区局部变为30°后又恢复为60°,表面被二叠系中统范家屯组和上统一拉溪组、燕山早期碱长花岗岩、张广才岭玄武岩及第四系所覆盖;其次为北西向和北北东向和东西向构造,构造性质不明。区内岩浆活动强烈,岩浆岩发育。The main exposed strata in the gold polymetallic ore area of Quangou are daheshen formation and Fanjiatun formation of the Middle Permian.The fault structure in this area is relatively developed.The NE trending super crust deep fault structure,Dunhua Mishan fault,passes through the area,with an overall strike of 60°and recovers to 60°after it changes to 30°locally in this area.Its surface is covered by the Fanjiatun formation of the Middle Permian system,the upper unified Laxi formation,the early Yanshan alkali feldspar granite,the zhangguangcailing basalt and the quaternary system,followed by the NW and NNE The structural nature is unknown.Magmatic activity is strong and magmatic rocks are developed in the area.
