| 摘 要： | 对相山铀矿田西部的邹家山矿床矿石中的萤石进行了系统的流体包裹体研究，结果表明取自邹家山矿床-130m和206m标高样品流体包裹体的均-温度平均值分别为266．1℃和159．9℃，盐度平均值分别为11．61wt％和13．16wt％，密度平均值分别为0．88g／cm^3和1．00g／cm^3。流体包裹体均-温度与盐度之间的关系呈抛物线型，密度与均-温度呈明显的负相关关系，而密度与盐度成正相关关系。计算获得邹家山矿床-130m和206m标高铀的平均成矿深度分别是553m和65m，表明矿床形成后遭受一定程度的剥蚀，其剥蚀深度大约在65～150m。

| Abstract: | The homogenization temperature and the melting temperature of fluid inclusions of flourite samples at depth -130 m and 206 m elevation in Zoujiashan uranium deposit have been measured systematically by microthermometry. The average of homogenization temperature of fluid inclusions is 266. 1℃ and 159.9℃, the average salinity is 11.61wt% and 13.16wt%. The mean density of fluorite inclusions is 0.88 g/cm^3 and 1.00 g/cm^3. The homogenization temperature shows an parabola correlation with salinity, negative correlation to density, the density is positive related to salinity. From this data and relation we caculated out that the uranium orebodies at -130 m and 206 m elevation were formed at the depth of 553 m and 65 m, which means that Zoujiashan uranium deposit was suffered a denudation of about 65 to 150 m after its formation. |
