铀矿床成因模式的建立,要从研究地质过程中铀的迁移着手,包括对成因概念的阐述、最终建立基本模式。这些模式都是以已知的铀矿床成因为基础的,但应注意,一种成因模式可能综合了几种类型铀矿床的主要形成条件。本文介绍了8个成因模式,它们的完善实际上涉及到所有已知的大型铀矿床。由于考虑到在7个地质年代阶段中成矿作用的演化,在评价研究区铀矿远景时应用这些成因模式是可能的。7个阶段是:(1)基本铀源的完善;(2)局部铀源的形成(含
The establishment of uranium deposit genetic model should begin with the study of the uranium migration in the geological process, including the explanation of the genesis concept and the ultimate establishment of the basic model. All of these models are based on the genesis of known uranium deposits, but it should be noted that a causal model may have integrated the main formation conditions for several types of uranium deposits. This article describes eight generative models whose perfection actually involves all the known large uranium deposits. Given the evolution of mineralization in the seven geochronological stages, it is possible to apply these patterns of origin in the evaluation of uranium prospects in the study area. The seven stages are: (1) improvement of basic uranium source; (2) formation of local uranium source
