摘要
吉林省夹皮沟金矿区金矿赋存在夹皮沟北西向韧性剪切带内，控矿构造为叠加在韧性剪切带之上的脆性构造。中生代中酸性脉岩为成矿期脉岩，且与黄泥河花岗岩岩基有着密切的成因联系。成矿物质主要来自岩浆分异，金丰度值高的暗色岩类提供部分矿质。
The Jiapigou gold deposit is located in the NW trending ductile shear zone. However, the ore controlling structures are the brittle fractures overprinted on the ductile shear zone. Mesozoic intermediate and acidic dykes which are closely related to Huangnihe granite were formed during the mineralization period. Ore-forming materials are thought to come from magmatic differentiation. Melanocratics rocks with high tenor Au could also provide some ore components.
