///Based on a study of the fluid inclusions of such minerals as scheelite, quartz, diopside, fluorite and calcite in skarn and quartz veins, the authors studied the favorable temperature, salinity, pressure and depth of the ore fluids in the Zhongbao tungsten deposit, and comparatively investigated ore-forming phases and stages and geological characteristics, thus determining the evolution features of the fluid. All of these data indicate that this ore deposit is a middle-high temperature skarn tungsten deposit.
