Characteristics of Fluid Inclusions in Changpai Uranium Deposit in the Southern Zhuguang
The Long Row uranium deposit is a newly discovered large uranium deposit in granite.In order to explore the genesis of the deposit,the fluid inclusions of quartz,calcite and fluorite during the mineralization period were studied.The results show that the fluid inclusions are of H2O type,with two intervals of homogeneous temperature ranging from 200.4～214.6℃ and 181.2～197.2℃,and the average values of fluid salinity in different samples from different boreholes are basically the same,and the mineralizing fluid is a medium-low-temperature,low-salinity NaCl-H2O fluid.The deposit is a medium-low temperature hydrothermal deposit formed by the miscibility of medium-low temperature,low salinity fluid and medium-high temperature,high salinity fluid.
