摘　　要：芳畈—青山口矿带是产出在鄂北中深变质岩区的一条铜、铅、重晶石矿带。文章依据岩石地球化学分析结果的统计分析和硫、氧同位素测定结果,讨论了矿带内矿床的矿质来源、水源、热源等3个矿床成因问题,认为矿带内不同地段不同矿种的矿床属“三源”不同的热液矿床。The Fangfan - Qingshankou ore belt is a Cu - Pb - barite mineralzing belt located in medium - deep metamorphic rock region in the north Hubei province. Based on rock geochemistry analysis data and sulphur and oxygen isotope determination, sources of ore - forming materials, fluids and heat for ore genesis in the belt are discussed. It is concluded that ore deposits with different ore type in the different sector of the belt belong to different hydrothennal deposits with ＂three sources＂,
