根据对于法国铀矿矿脉所作的研究及世界文献,特别是第一次日内瓦会议(1955年)以后发表的世界文献,作者将矿床分为两大类: 其一,和酸性岩分异有关的铀矿床,自然应划出来热液型。其二,和上一类完全不同,是和某些地质年代的构造运动有关,铀在大面积的岩石中呈分散状态存在。我们已经注意到,将某些铀矿床按照成因分类是有困难的。因此我们在这里建议一种构造分类,理由是考虑到: (一)铀矿床的位置和酸性岩密切相关。这种酸性岩所有专家都认为是铀的母岩,而不论其析出和富集作用如何; (二)由于热液脉影响而产生的盖层变质程度;
Based on studies of French uranium veins and world literature, especially the world literature published after the First Geneva Conference (1955), the authors classify the deposits into two broad categories: first, uranium Deposits, nature should be drawn hydrothermal type. Second, totally different from the previous one, it is related to tectonic movement in some geologic times, and uranium exists in a dispersed state in a large area of rock. We have noticed that it is difficult to classify some uranium deposits by cause. Therefore, we propose here a tectonic classification based on the following considerations: (i) The uranium deposit is closely related to acid rock. All experts of this acidic rock consider the parent rock of uranium, regardless of the role of precipitation and enrichment; (2) The degree of metamorphism of the cover due to the influence of hydrothermal veins;
