| 摘 要： | 从地球化学角度,利用古气候条件和相关地球化学指标分析,指出研究区赋矿岩石形成于干旱的氧化环境;通过分析与铀矿化常见伴生元素组合结果,指出目的层曾遭受过不同程度还原性流体的改造,并在构造抬升期,地表氧化性流体顺层对目的层进行了再次改造,铀矿化则发生于两种不同性质流体混合改造部位。

| Abstract: | By studying the palaeoclimate and metallogenesis related geochemical indexes,this paper proposes that the hosting rocks should form in geochemical oxidation setting under arid palaeoclimate.The study on element assemblage associated with uranium mineralization indicates that the target hosting rocks suffered from different degrees of reworking of reducing fluid at first and then being superimposed by supergene oxidative fluid at tectonic uplifting stage.The uranium mineralization is located in reworked and superimposed places of two types of fluid. |
