| 摘 要： | 所研究的矿床为一个大型隐伏铀矿床,是华南铀成矿区一个典型的花岗岩型铀矿床。本文重点研究了该铀矿床主成矿阶段微晶石英的标型特征。在矿床垂直方向上,微晶石英的杂质组分、晶胞参数和人工热释光(ATL)性质均显示较大的变化。微晶石英标型特征的这些差异可以作为研究隐伏铀矿床垂直分带的有效手段,并可用于判断其侵蚀截面。

| Abstract: | The studied blind uranium deposit is a large granite-hosted deposit typical of the metallogenic province in South China. This paper is concerned with typomorphic quartz formed at the main stage of mineralization. In the vertical direction, there are great differences in impurities, cell parameter and artificial thermoluminescence (ATL) of microlitic quartz. These typomorphlc peculiarities of microlitic quartz can be used to study vertical zoning and localize the erosion surface of the blind uranium deposit. |
