| Abstract: | This papre focuses on the physicochemical conditions of uranium mineralization inGuangshigou granite-pegmatite type uranium deposit and the mechanism of migration and precip-itation of uranium in the pneumatolytic hydrothermal solution according to the theories and meth-ods of thermodynamics. The studies show that U-bearing pneumato hydrothermal fluid is a re-ductive and acidic medium. Among it is a predominant form of uranium migration. In themineralized period,the formation of biotite reduce the content of fluorine and make in thestate of hydrolysis and form uraninite. |
