摘　　要：文章通过对彩霞山铅锌矿床硫、碳、氢、氧同位素的研究,探讨了矿床成矿流体来源及演化,揭示了成矿作用过程中的某些重要信息。初步认为矿石中的硫主要来自同化了海水硫酸盐的岩浆硫,同时有少量生物还原硫参与;碳、氧同位素组成指示碳来源于壳幔混合。成矿流体以建造水为主,早期有岩浆水参与。Sulfur, carbon, hydrogen and oxygen isotope of Caixiashan lead -zinc deposit were analyzed to discuss origin and evolution of ore- forming fluids, and to proclaim some useful genetic information for the mineralization, It is shown that sulfur of ores mainly comes from granitic magmas which assimilate sulfate in the sea, with involvement of small amount organic reductive sulfur. Composition of carbon and oxygen isotope indicates that origin of carbon comes from mixture of the crust and mantle. Ore- forming fluids are mainly made up of formational water, and comprised magmatic water in the early stage.
