摘　　要：本文运用宏观和微观、地质和地球化学相结合的方法，通过野外观察和岩矿石中微量元素、稀土元素、同位素及流体包裹体的分析，探讨了铜陵地区成矿物质和含矿流体的来源及性质。研究表明，铜金等金属有岩浆和地层两个来源，但以前者为主；硫的来源有三：即地层、岩浆热液和地下水热液；含矿流体来源早期以岩浆为主，晚期有地层水的加入。This paper,based on field work and analyses erelements,REE,isotopes and fluid and inclusions,discussesmesource of ore forming material and ore bearing fluid of the Tongling area in terms of combination of macorscopeand microscope,geology and geochemistry.Study shows that copper,gold etc,are derived from two sources:magmaand strata,of which the former one predominates,and that sulphur is from three sources:strata,hydrothermal solutionsof magma and groundwater. Ore bering fluid was orignated from magmatic water for the early period and wjth ihtro-duction of strata water for the late.
