| 摘 要： | 本文在介绍并分析美国和前苏联总结的砂岩型铀矿区域评价判据的基础上, 引入当今碎屑岩沉积学和盆地地球动力学方面的若干新进展, 提出以主砂体及其随后经历的构造改造样式相结合的盆地产铀远景评价判据和以分析区域构造活动史和原型盆地演化相结合的盆地产铀远景评价模式。最后以潮水盆地为例, 具体分析了盆地各个时代盖层容存后生铀矿化的可能性, 指出盆地中的主要找矿目标层位和远景成矿地段。

| Abstract: | On the basis of the introduction and the analysis of regional evaluation criteria for sandstone-type uranium deposits summarized by uranium geologists of USA and former Soviet Union,and by introducing new scientific progress in the field of sedimentology of clastic rocks,and basin geodynamics,main evaluation criteria composed of host sand body criterion and the criterion of structurally reworking pattern the host sand body has been subject to, are proposed,and the evaluation model based on analyzing the regional tectonic history and the evolution of prototype basin is set up.Finally,taking the Chaoshui basin as an example,the possibility for hosting epigenetic uranium mineralization in each horizon of the basin cover is discussed,then the main prospecting target horizon is discriminated,and potential ore-formation areas are proposed. |
