The petrography and temperature from the fluid inclusions in the opaque minerals in the Yaogangxian quartz-vein wolframite deposit are studied and tested under infrared microscope, and correlated those with the fluid inclusions in the transparent mineral quartz coexisted with wolframite. There are three dominant types of fluid inclusion in wolframite, liquid-rich inclusion, gas-rich phase inclusion and pure liquid fluid inclusion. The features reveal that the ore-forming fluid of wolframite is characteristic of medium temperature, medium salinity and low density, while the fluid in quartz belongs to low temperature, low salinity and low density. According to microthermometry data of the fluid inclusions and previous study, it is considered that the ore-forming fluid in Yaogangxian tungsten deposit may come from magma.
