The Shanhu tungsten-tin deposit is a typical greisen type tungsten-tin deposit. After the micro-scopic temperature test in the fluid inclusions,the following results are obtained:(1 )The main types of fluid inclusions are liquid rich liquid-vapor fluid inclusions ,there are also a small number of pure liquid inclusions and clusters of secondary inclusions;(2)The homogenization temperature ranges from 190℃ to 260 ℃,the freezing points range from -3℃ to -5℃,the salinities range from 7% to 11%,and the flu-id density ranges from 0. 760 to 0. 945 g/cm3 . It can be speculated that the ore-forming fluid is the fluid with medium temperature and low salinities;(3 )On the basis of the homogenization temperature-salinity scatter diagram,it can be inferred that the enrichment and deposition of the ore-forming matters are con-nected with the boiling of the ore-forming fluid,and that it has been influenced by exotic water.%珊瑚钨锡矿床是一处典型的大型云英岩型钨锡矿床,通过包裹体显微测温得到如下结论:(1)珊瑚矿区包裹类型较简单,主要是富液相两相包裹体,少量的纯液相包裹体,而次生包裹体多成群分布;(2)包裹体的变化温度范
