In order to explore the uranium mineralization specific characteristics of granite， the geochemical characteristics of Mesozoic-producing and non-producing uranium granites in the Nanling region were analyzed on the base of systematic collection of previous research. The results show that both uranium deposit host and non deposit granites are mainly formed by partial melting of Precambrian metamorphic sedimentary rocks，but the uranium deposit host granites are mainly formed by partially melting U-rich mudstones, while the non-deposit granites are the partially melted products of uranium-depleted sandstone. Compared with uranium deposit host granites，the biotite crystallization temperature in uranium deposit host granites is relatively low，F-rich and Cl-poor，and the magmatic melt has lower oxygen fugacity values，suggesting that uranium deposit host granites formed at relatively low temperatures and low oxygen fugacity. The low temperature, low oxygen fugacity，and F-rich physical and chemical environment are favorable for U to continuously enter the melt during the magma crystallization and differentiation and combine with oxygen to form uranite that are liable to undergo secondary alteration. The formation of uranite provides a good material basis for uranium mineralization.
