FLUID INCLUSUION MICROTHERMALMITRY OF 302 URANIUM DEPOSIT IN THE NORTH PART OF GUANGDONG PROVINCE, CHINA

摘要

Fluid inclusions in ores from the 302 uranium deposit were grouped into three types: the liquidrich, the vapor-rich and the CO_2-rich fluid inclusions. The homogeneous pressures of these of fluid inclusions were used to estimate the depths and the vertical amplitude of uranium mineralization. The study indicated that the uranium mineralization was 2.65 km in high level and 3.54 ~ 7.16 km in low level underground in its deposition age. The vertical mineralized amplitude was 2.7 km in conservative estimation.
