Abstract

Abstract

Study of fluid inclusions in calcite, quartz and fluorite in the Shazhou deposit, Xiangshan uranium orefield, Jiangxi, indicates that::the homogenization temperatures of ore fluids ranged from 200 to 210℃ and from 230 to 260℃; the salinities ranged from 11.01 to 12.00% wt.% NaCl equivalent and from 18.01 to 20.00% wt.% NaCl equivalent; the average density was 0.94 g/cm³; the oreforming pressures ranged from 168.4×10⁵ to 433.0×10⁵ Pa with an average of 283.8×10⁵ Pa.The oreforming depths estimated based on the relation between pressure and depth ranged from 0.561 to 1.443 km with an average of 0.946 km.According to the abovementioned, combined with an analysis of the composition of fluid inclusions and the stable isotope data, the authors conclude that the ore fluids of the Shazhou uranium deposit were mainly derived from meteoric water, mixed with small amounts of magmatic water and mantle-derived hydrothermal fluids.
