在铀矿床总量中外生后成铀矿床占有重要的地位。地下溶浸法的运用使人们改变了对这些虽然相对贫铀,但易加工的地质体的看法,并且在很大程度上扩大了此类型新矿床的普查勘探工作。后生铀矿床的普查是以淋滤成因概念为基础。此概念对扩大铀矿资源基地起了重要的作用。二十五年来积累的岩石、矿物-地化和水文地质等方面大量的资料可以对沉积铀矿床的后生淋滤分带性作更详细的研究,并把分带性广泛运用到成矿预测和普查勘探中。一般认为沉积铀矿床赋存在小型自流盆地中。那里的山区作为含氧含铀地下水的补给区。当这些含
The total amount of uranium deposits in the post-uranium deposits occupy an important position. The use of the subsurface immersion method has changed the perception of these relatively depleted uranium but machinable geologic bodies and has largely expanded the census work of this type of new deposit. The census of epigenetic uranium deposits is based on the concept of leaching origin. This concept has played an important role in expanding the uranium resources base. A large amount of data on rock, mineralogy, geology and hydrogeology accumulated over the past 25 years can make a more detailed study on the epigenetic leaching zonation of sedimentary uranium deposits and apply zonation to the prediction of mineralization and Census exploration. Sedimentary uranium deposits are generally believed to exist in small gravity basins. The mountainous area serves as a recharge area for uranium-bearing groundwater. When these contain
