表1中所列的十九类铀矿化当中,在目前仅有六类具有经济价值。它们是:砾岩型、砂岩型、钙质结砾岩型、内侵人体型、热液脉型、似脉型。不同类型铀矿床的形成与一定的地质环境有关,即:1.第一类铀矿化在内生作用条件下形成;2.第二类铀矿化是第一类铀矿化在以后的表生作用条件下变化形成的;3.第三类铀矿化推测可能是在内生变质过程中形成的。但是,对第三类铀矿化在变质作用期间铀的活动情况了解的很少,因而,它的成因还很不清楚。铀矿床的成矿构造与地质年代研究表明,铀矿床的形成与一定的地质年代有密切的关系。它主要出现在太古代末期至下元古代时期和海西期(上石炭纪至下二迭纪),部分地出现在研究尚不够的上元古代时期。
Of the 19 categories of uranium mineralization listed in Table 1, only six currently have economic value. They are: conglomerate type, sandstone type, calcareous conglomerate type, intrusive human type, hydrothermal pulse type, pulse type. The formation of different types of uranium deposits is related to a certain geological environment, namely: 1. The first type of uranium mineralization formed under endogenous conditions; 2. The second type of uranium mineralization is the first type of uranium mineralization in the future 3) The third type of uranium mineralization may be formed during the process of endogenous metamorphism. However, little is known about uranium activity during the metamorphism of the third type of uranium mineralization and, as a result, its cause is poorly understood. The study of metallogenic structure and geology of uranium deposits shows that the formation of uranium deposits is closely related to the geological age. It occurs mainly from the Late Archean to the Lower Proterozoic and the Hercynian (Upper Carboniferous to Lower Second Permian), partly in the period of the Paleoproterozoic that was not yet fully studied.
