摘　　要：文章对富铀地质体与成矿铀源关系进行了多方面的讨论,分析了铀在不同地质作用下的迁移行为以及铀发生迁移的主要受控因素,认为富铀地质体对铀的氧化-还原成矿提供了成矿的重要铀来源;但热液成矿中铀的主要来源是在广泛的区域变质作用及之后岩石圈频繁的构造-岩浆活动作用期间,受深部各种热及特殊流体的共同作用驱使下引起的从高热场向低热场发生的铀迁移,而非来自低热场的成矿周边富铀地质体。分析认为富铀地质体是伴随铀成矿作用形成的产物,在物质成分组成上与成矿必然具有相似性或继承性,也是内生铀矿找矿的直接标志。By discussing about the relationship between rich uranium geological body and source of uranium mineralization,analyzing the migration behavior and the main control factors of uranium under the different geological process,it is believed that the important uranium source of the oxidation-reduction mineralization mainly come from the rich geological body.However,the uranium source of hydrothermal mineralization mainly come from the extensive regional metamorphism and subsequent tectonic-magmatic activities of the lithosphere after metamorphism,the transfer of uranium from a high thermal field to a low heat field is driven by a combination of various heat and special fluids in depth,rather than the low-heat field from the surrounding mineralization of rich uranium geological body.The uranium deposits surrounding the mineralization surrounding the low-heat field.So that the rich uranium geological body is formed with the formation of uranium mineralization,it is bound to be similar or inheritable in the composition of material composition,and it is also a direct sign for prospecting endogenous uranium mine.
