The Baoguto porphyry copper deposit locates in south of the Darbut magmatic arc of the western Junggar. The northeast regional structure mainly composed by a series of major faults. The Baogutu intrusion is an intermediate porphyry with several lithologies and lithofacies. Mineralization type is disseminated mineralization，veinlets and network mineralization. The oreforming process can divided into three phases. Fluid inclusions data showed：homogenization temperatures from the first stage to the third stage gradually reduced，indicating that mineralization from early and late going through a cooling process. Fluid density 065～115 g/cm3，estimates of mineralization pressure of 1260×105～9501×105 Pa，and depth of 042～317 km，Gas fluid inclusions are mainly CH4，N2，C2H4，mainly for liquid H2O，and contain a small amount of CO2-3.
