| 摘 要： | 作者对伊犁盆地的铀矿化同位素年龄进行了分析研究，发现层间氧化带砂岩型铀矿的主要矿化期开始的时代与盖层间最新一个不整合面上覆地层时代相吻合的地质事实。在对铀成矿机制进行期的基础上，提出了层间氧化带砂岩型铀矿成矿阶段应在盆地经历最新一次构造不整合运动后的盖层演化阶段（本文称之后构造不整合阶段）的认识。并由此进一步分析了伊犁盆地轴成矿条件与矿化空间分布之间的关系，认为控制成矿空间的关键因素是后构造不整合

| Abstract: | The study on space time distribution of uranium mineralization in Yili basin shows that the main metallogenic epoch of interlayer oxidation zone sandstone type uranium deposit occurred simultaneously with the appearance of the latest unconformity and the age of overlying sediments. The ore hosting space is mostly controlled by the strength of tectonic activity during the structural unconformity period. Based on the above conclusion and the analysis on the economic technological requirement for prospecting ore control parameters, this paper proposes new ideas and prospecting strategy for interlayer oxidation zone sandstone type uranium deposit. |
