摘　　要：近年来,有关岩浆热液矿床源区硫化物熔体的熔离过程及其对成矿的贡献已引起相当的重视。在系统地介绍热液矿床岩浆源区原生硫化物熔体分离机制,以及其对成矿金属元素的初始富集行为基础上,重点综述了岩浆硫化物熔体破坏分解并参与到成矿流体的具体过程和实例。同时对该领域的关键技术方法LA-ICPMS原位微区成分测试的进展进行了概述,并提出了一些研究展望,尤其是深部岩浆演化中成矿金属元素的富集迁移过程。The identification of sulfide melt exsolution in deep magma chamber and its contribution to hy- drothermal ore formation has drawn much attention in recent years. This paper systematically introduced the generation of primary sulfides in magma and their behavior of enriching ore-forming metals which dis- persed in silicate melt. Furthermore, this paper overviewed the processes and examples of sulfide melt be- ing destabilized instantaneously during later stage of the magma evolution and metals being released to an ore-forming hydrothermal fluid. In addition, the development of in-situ LA-ICPMS analytical method was summarized in this paper. At last, the paper proposed potential suggestions for the future research on par- ticular enrichment and migration of ore metals in deep magma evolution.
