The Xi’an tungsten deposit, located in the middle of Xi’an gold antimony tungest metallogenic belt, western Hunan, is an important tungsten deposit in South China. In order to places emphasis on mineralogy of the scheelite, based on the previous researches, using mineralogical, this dissertation documents the geological feature of the studied deposit. This study investigated the scheelite deposit is hosted in the Madiyi Formation of Proterozoic Banxi Group. Its ore bodies, occurring as stratiform and stratoid, are strictly controlled by strata, lithology and structure. The chemical formula of scheelite collected from the studied deposit is Ca 0.96 W 1.02 O 4.02 , and its content of CaO is less than the theoretical value, while the content of WO 3 is bigger, and the latter tends to increase with depth from deep to shallow. The crystal parameters for scheelite are close to the theoretical value.
