The main points of view in this paper are as follows: 1) The assemblages of granites represent the granitic evolutionary sequences if they are located in the common geological element and associated with the closed genetic relation and the order of their formation are determined definitely enough. 2) The Mesozoic granites from Zhuguangshan Batholith represent an ex- ample of biotite-two-mica/muscovite granitic type of evolutionary sequence. They can be divided into three evolutionary cycles and six intrusive stages. The beginning member of each cycle is composed of coarse-grained or medium- grained biotite granitic rocks and the end inember-fine-or medium-grained two mica/muscovite granitic rocks. The geological and petrochemical data in- dicate that this type of evolutionary processes depend on the fH,o and fo2 conditions. 3) Investigation on the granitic evolutionary sequence is an important work and the various ore deposits are related to the different types of evolutions.
