鈾矿床中有一定的元素共生組合,它反映元素在成因上的有机联系,也体現了鈾及其伴生元素在地壳中运移和定集的結果。根据鈾矿床(或鈾富集区)元素的共生組合及元素的生、运、定的关系,将主要內生鈾矿床划分为下列五个类型(表1)。按照不同的实用目的与成因解释,不同学者采用过不同的标志对鈾矿床进行过分类,例如,鈾矿床形成的大地构造条件、矿床类型的形态及鈾的沉淀方式、矿石类型。而欧美学者多以成矿的物理化学条件、矿石沉淀深度、围岩性质、成矿时代等作为分类标志。关于鈾及其有关元素的来源問題,学者們往往从鈾元素的地球化
Uranium deposits have certain element symbiotic combinations, which reflect the elemental genesis of the organic connection, and also reflect the uranium and its accompanying elements in the crust of the migration and set results. According to the symbiotic composition of uranium deposit (or uranium-enriched area) elements and the relationship between elements, transport and distribution, the main endogenous uranium deposits are classified into the following five types (Table 1). According to different purposes and causes of interpretation, different scholars have used different signs of uranium deposits were classified, for example, uranium deposits formed geotectonic conditions, the type of deposit type and uranium precipitation, ore type. The European and American scholars and more to the physical and chemical conditions of mineralization, ore deposition depth, the nature of rock, metallogenic era as a classification mark. On the source of uranium and its related elements, scholars often from the uranium geochemistry
