地壳重熔程度和重熔岩浆结晶分异演化程度直接反应了岩浆能态的高低;岩浆能态高低决定了铀矿化类型及其远景意义。研究区位于华北地台南缘的加里东褶皱带中。L、D两区均以前寒武纪变质岩为基底,广泛发育加里东期花岗岩,褶皱断裂发育。L区为拱断区,以断裂重熔释放地幔热流为特点,以高能态花岗为主,深成壳熔呈带状展布,岩浆化程度高,成岩持续时间长,岩浆演化完善。宏观
The degree of crustal remelting and the degree of differentiation and evolution of reclaimed magma directly reflect the state of magma energy. The magma state determines the type of uranium mineralization and its long-term significance. The study area is located in the Caledonian fold belt on the southern margin of the North China Platform. Both L and D zones are based on the Precambrian metamorphic rocks, and extensively developed Caledonian granites with fold-rupture development. The L zone is an arcuate zone, characterized by faulting, remelting and release of mantle heat. High-energy granites dominate. The deep crusts melt ribbon-like distribution with high degree of magmaticization, long diagenesis and perfect evolution of magma. Macro
