摘　　要：金厂峪金矿产于八道河群王厂组,矿体受刘村寨—双沟峪复式向斜控制,成矿与中生代构造作用及岩浆活动有密切关系。矿床的形成经历了复式向斜构造的形成;与岩浆活动有关的成矿热液沿构造薄弱带运移;热液蚀变及矿质沉淀。硫、氧、碳、铅同位素数据表明成矿物质来源于深部,与矿床围岩具有不同的属性。The Jinchangyu large-scale gold deposit lies in the Wangchang formation of Badaohe group famous in eastern Hebei. It is con-trolled by the Liucunzhai -Shuanggouyu composit anticline. The mineralization is closely related to the Mesozoic tectonesm and mag-matism. The gold deposit underwent the formation of the composit anticline; the transportation of magma-related ore-bearing hy-drothermal fluids along tectonic zone; the precipitation ore-bearing hydrothermal fluids. According to the Carbon, Oxygen, Suffer, Lead isotopic data, the ore- forming material is characterized by deep source, and is not derived from the wall rock of the gold de-posit.
