Abstract
According to the occurrence and forming age of magmatic rocks and its relationship with stuc-tures.The magmatic evolution was devided into two vocanic series of rhyodacite porphyroclastic rhyolite annular granitic porphyry and veined rock series of granite porphyry lamprophyre diabase, respectively.Granite porphyry was devided into two stages:the early stage annular granite porphyry was mainly controlled by volcanic structures and the late stage veined granite porphyry was mainly controlled by faults,respectively.The studies of rock ages and genesis indicated that the vocanic series are probably derived from different degree of partial melting of crust in the Early Cretaceous,while the veined rock series belong to the products of partial melting of mantle and crust caused by mantle activity.Uranium mineralization is closely related to veined rock series in space time and genesis.关键词
