The quartz vein-type and skarn-type are the most important kinds of tungsten deposits, are different in the ore forming process and mechanism. The metals mostly are of igneous sources in the skarn-type deposit, a giant brecciation communicate the magma and groundwater systems, which leads the hydrothermal fluid mixing with meteoric water, is the important role of the ore forming. Different from skarn type deposit, in the tungsten-bearing quartz vein system, there are large scale fracture controlling vein but no obvious vertical mineral zoning, no Pb-Zn deposits around the skarn, no breccia, and no obvious evolution stages. The homogenization temperature, salinity of the fluid inclusion are small range, i.e. 200°C~400°C, 2~8wt%NaCl, no evidence of boiling, no obvious mixing of magmatic and meteoric water, and no obvious decrease of the temperature and salinity in the evolution of the hydrothermal system. The ore-forming metals and water come from magma, no obvious meteoric water takes part in. Contract to the “opening” of the skarn-type deposit, tungsten-bearing quartz-vein formed in a relative closed system. The wall rock alteration of the vein is weak, and there is no obviously change of δ18O and δD values of the fluid inclusion, which suggests that the water/rock ratio of the ore forming system is very low. It is show that the vein formed from the fluid with low-water, rich in metals and silicon, but not from traditional post-magmatic hydrothermal.
