铀成矿作用的基本条件是地壳表层富铀体(层)经各种地质改造作用形成铀元素的相对富集。因此分析研究一个地区铀源体(层)的形成和发育情况以及其分布规律将有助于查明这一区域铀成矿远景。华北地台由数个构造层所组成,其基底约90％由太古代变质岩系组成,10％由早元古代变质岩系组成。地台上覆中、晚元古代、古生代盖层建造及中、新生代的上迭建造都是基底构造层的改造产物。因此基底构造层的岩石建造组合、变质和混合岩化
The basic condition of uranium metallogenesis is the relative enrichment of uranium elements formed by uranium rich body (layer) on the crust surface through various geological remodeling. Therefore, the analysis of the formation and development of uranium source bodies (layers) and their distribution in a region will help to identify the prospect of uranium mineralization in this region. The North China platform consists of several tectonic layers. About 90% of its basement consists of Archean metamorphic rocks and 10% of Early Proterozoic metamorphic rocks. Overground platform, the late Proterozoic, Paleozoic caprock and the Mesozoic, Cenozoic building up the Diego are structural transformation of the basement product. Therefore, the rock of the structural layer of the basement is composed, metamorphosed and mixed with petrified rocks
