| 摘 要： | 笔者通过对512铀矿床含矿层岩石中铀同位素分布特征的研究，对砂岩型铀矿床铀同位素组成的分区进行了讨论。根据不同氧化还原分带中样品铀同位素组分的分布特征，对Osmond铀钍同位素组成分区模式提出了补充修改意见，认为A区应定名为“地球化学（氧化还原）矛盾区”更宜。该砂岩型铀矿床的铀同位素组成分区特征不仅是预测铀矿化定位的依据，而且也充分说明了铀富集成矿过程的滚动性。

| Abstract: | Based on the study of composition of uranium isotopes in deposits No. 512, the composition distribution of uranium isotope for the uranium deposits of sandstone type are discussed. According to the distribution of uranium isotope samples in different oxidation reduction zones, the region A should be named as the region of geochemical conflict. The distribution of uranium isotope composition is not only can be used to predict the location of uranium ore body, but also can be used to study the rolling of the roll during the process of the ore body formation. |
