铀矿与红层有一定的关系,红层在铀成矿过程中起重要作用。文章通过对西北及山西、内蒙古七省(区)地质发展史的分析,将西北地史上所出现的红层划分成6个红层期,并详细阐述了各期红层的特征及演化规律。探讨和研究了红层在铀成矿过程中所起的作用及两者的内在联系。明确提出铀矿床与红层(盆)在形成时间上具有同时性,在空间分布上具有相伴性,在地区、类型上具有普遍性;铀矿化主要与干热气候条件下形成的陆相红层有关,而与海相红层的关系不密切;凡是有矿的地方,附近必定有红层,但有红层的地方不一定都有矿;在剖面上大型铀矿床只发育在红层之下或红层之上。探索了红层与富矿的关系。在综合分析的基础上,提出了红层期成矿的理论及与红层(期)有关的铀成矿模式。
There is a certain relationship between uranium ore and red beds. Red beds play an important role in uranium mineralization. Based on the analysis of the geological history of the seven provinces (regions) in Northwest China, Shanxi and Inner Mongolia, the paper divides the red layers in the history of Northwest China into six red layers and expounds the characteristics and evolution rules of each layer in detail. The role of red beds in the process of uranium mineralization and the intrinsic relationship between the two are discussed and studied. Clearly put forward that the uranium deposit and the red beds (pots) have the same time in the formation time, and have the concomitancy in the spatial distribution, which are universal in the types and types. The uranium mineralization is mainly related to the terrestrial red beds formed in the dry and hot climates , But not closely related to the marine red beds. Where there is a mine, there must be a red layer in the vicinity, but there is not necessarily a mine in the place where the red layer is located. Large uranium deposits in the section are only developed under red beds or Above the red layer. Explore the relationship between red beds and rich ore. Based on the comprehensive analysis, the theory of red-phase metallogeny and the uranium metallogenic model related to the red layer (period) are put forward.
