| 摘 要： | 诸广－九嶷地区富铀矿床的典型沥青铀矿，明显地表现出低落曙浅成的晶胞参数、含氧系数等标型特征及矿石放射性同位素特征，表明富铀矿区的铀成矿作用是在原生热液成矿作用的基础上叠加有后生水成（淋积）作用。富铀矿区黑色岩系中过成熟及石墨化的有机（碳）质，为铀的水成（淋积）成矿提供了优越的环境。

| Abstract: | A series of typomorphic characteristics such as typical colloidal texture, unit cell parameter, oxygen coefficient, and radioactive isotopic features of ores showing obviously epithermal origindemonstrate that the uranium metallogenesis of rich uranium ore areas in Zhuguang-Jiuyi region results from Primary hydrothermal metallization with superimposition of epigenetic (hydrogenic) infiltration. The overmatured and graphitized organic matter of the black shale series in rich uranium ore areas provides favourable environment for the hydrogenic (infiltration ) uranium metallogenesis. |
