| 摘 要： | 本文利用显微测温学和激光喇曼光谱方法,研究了661铀矿床与铀成矿作用有关的脉石矿物(萤石、石英和方解石)中的流体包裹体。结果表明,成矿早期脉石矿物中的流体包裹体均一温度为130~250℃,盐度为1.65%~3.44%(NaCl),密度为0.81~1.01 g/cm3;成矿晚期流体包裹体的均一温度为95~150℃,盐度为1.48%~1.64%(NaCl),密度为0.88~0.96g/cm3。这些资料揭示出该矿床的成矿流体为中低温、低盐度、中等密度热液。激光喇曼光谱气相成分分析主要为H2O,未见其他气体成分。明显不同于岩浆热液矿床中的包裹体特征及其成矿流体的性质,结合该矿床成矿地质特征、氧同位素及区域铀矿床成矿物化条件等资料,进一步分析推断成矿流体的水可能主要来自大气降水。

| Abstract: | The No.661 uranium deposit occurs in rhyolite of the Jiuliping Formation,the eastern part of Ganhang uranium belt,Zhejiang Province.The microthermometry and laser Raman spectroscopy analyses of fluid inclusions in fluorite,quartz and calcite associated with uranium mineralization were used to characterize chemical evolution of the ore fluids at the No.661 uranium deposit.Two types of inclusions,liquid and liquid-vapor inclusions,were observed in these minerals.The homogenization temperatures of the liquid-v... |
