| 摘 要： | Granites are widespread in the Nanling region of Chian ,which were emplaced in different tectonic environments as a result of frequent and intense magmatic activity.Two evolution sequences have been distinguished:the extrusive-hypabyssal and plut onic-hypabyssal sequences.Different mecha-nisms governing the evolution,especially the differentiation, of the two sequences may account for the different mechanisms of uranium mineralization leading to the formation of various types ura-nium deposits in the Nanling region.
