英文摘要	A significant porphyry-skarn tungsten metallogenic belt is located along the northwestern Jiangxi to the southern Anhui, Xiangjushan tungsten deposit is one of typical skarn deposits in this belt. The Xianglushan tungsten deposit has the characteristic of mineralization and alteration zonation, consisting of proximal skarn and veined quartz-scheelite orebodies and distal veined quartzsulfide-scheelite and lenticular orebodies. According to the microthermometry of fluid inclusions in gangue and ore minerals from various altered zonation, it shows that: the homogenization temperatures of fluid inclusions in skarn have a range of 209 383 C, the homogenization temperature ranges of fluid inclusions in the quartz-scheelite and quartz-sulfide-scheelite stages are 163 similar to 278 degrees C and 204 similar to 284 degrees C, respectively, and late calcite veins have the lowest range of 143 similar to 235 degrees C; the salinity of fluid inclusions in skarn has a range of 0.35% 5.26% NaCleqv, the salinity ranges of fluid inclusions in the quartz-scheelite and quartz-sulfide-scheelite stages are 0.35% 5.86% NaCleqv and 0.70% 9.21% NaCleqv, respectively, and late calcite veins have the range of 0.35% 2.07% NaCleqv. Raman microspectrokopic studies of the fluid inclusions of skarn, quartz-scheelite veins and quartz-sulfide-scheelite veins show that the main component of H2O, containing a certain amount of CH4 and a little of N-2. From the early to the late mineralization stages, the cooling processes might occur, which reflects the broad mineralization temperature of tungsten. Tungsten migrated in fluid possibly as a form of tungstic acids, through reaction with wall rocks; temperature decreasing and alkaline increasing induced the tungsten precipitation. From the early to the late stages the ore-forming temperature and material component variation caused the mineralization and alteration zonation.
