Based on a study of the fluid inclusions in fluorite from the Zoujianshan, Hengjian and Shazhou uranium deposits in the Xiangshan uranium orefield of Jiangxi, the authors have drawn the conclusions as follows: in the Zoujiashan uranium deposit, the average homogenization temperatures of fluid inclusions are 266.1 ℃ and 159.9 ℃ at the elevations of -130 m and 206 m, the average salinities w(NaCleq) are 11.61% and 13.16%, and the mean densities of fluorite inclusions are 0.88 g/cm3 and 1.00 g/cm³, suggesting that the regularity of homogenization temperature and salinity is of the parabola type. The density and homogenization temperature are significantly of negative correlation, and the density and salinity are of positive correlation.
