摘 要: | From years of experience with granite pegmatite, the authors note that granite pegmatite is of two different origins: magmatic differentiation autometasomatism and metamorphic differentiation. Granite pegmatites can be divided into nine types under four categories according to their formation mechanisms and the regularities of rare-metal evolution. Discussion is also given to the inheritance-development relationship between the various types of granite pegmatites, to the features of rare-metal mineralization and their spatial systematies of distribution.
