H-O isotopes of vein quartz in the Yaogangxian tungsten deposit, South China

Note: the δ18O-H2O values are calculated based on the average homogenization temperature of 256 °C of quartz using the equation of Matsuisha et al. (1979): δ18O-SiO2 − δ18O-fluid = 3.34 × 106/(Th + 273.15)2 − 3.31. The results are reported relative to the Vienna Standard Mean Ocean Water (SMOW) standard.
