摘　　要：霍各乞铜多金属矿床的地质-地球化学特征表明该矿床为有海底喷气参与的同生沉积作用所形成。区域变质及岩浆热变质作用对矿床改造也极为明显,但成矿物质重新活化、迁移、富集基本限于含矿层中。改造的结果使得矿床的硫、铅同位素产生均一化作用。Geological and geochemical characteristics of the Huogeqi copper-polymetallic deposit indicate that it is a product of syngenetic sedimentation with the participation of submarine exhalation. Regional metamorphism and magmatic thermometamorphism evidently reformed the ore deposit; nevertheless,remobilization, migration and enrichment of metallogenic materials took place mainly within the ore-bearing bed. The reformation has led to the homogenization of sulfur and lead isotopes in the ore deposit.
