Abstract: This paper focuses on geological characteristics of granitic pegmatite and mineralization of uranium and other rare elements in the Danfeng triangle area of North Qinling. According to the study, the granite pegmatite is produced by further differentiation of volatile-rich residual magma during late magmatic evolution. The granitic pegmatite mainly emplaced in Qinling rock group as well as the inner and outer contact zone of the mid-late Caledonian granite, distributing along the anticlinal axis and fracture, and parallel to the extension of structural lineament. Because of the metasomatic differentiation, the granite pegmatite has a broad category including biotite pegmatite, two mica pegmatite, muscovite pegmatite, muscovite Na-spar pegmatite and mica Li-spar pegmatite. The diagenesis and mineralization of granitic pegmatite can be divided into four stages, i.e. subsequent magmatism, germination, pneumatolysis and hydrothermal solution. With obvious multi-element mineralization characteristics, the granitic pegmatite is rich in rare metals such as U, Th, Nb, Ta and L, as well as other non-metallic mineral like beryl, mica, potassium feldspar etc.
