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_0.96W_1.02O_4.02, and its content of CaO is less than the theoretical value, while the content of WO₃ 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.

西安钨矿床位于湘西西安金锑钨成矿带中部，是华南地区重要的钨矿床。为了强调白钨矿的矿物学，本论文在前人研究的基础上，利用矿物学的方法，对所研究矿床的地质特征进行了记录。本研究考察了元古界板溪群马底伊组白钨矿床。其矿体呈层状和层状，受地层、岩性和构造的严格控制。研究矿床采集的白钨矿化学式为Ca _0.96 W _1.02 O _4.02，CaO含量低于理论值，WO _{3含量低于理论值。}较大，而后者往往随着深度从深到浅而增加。白钨的晶体参数接近理论值。
