The granites of south China are divided into three types on the basis of the geological Characteristics, evolutional law, minerlization process, material sources and genetic mode which has been revealed by them, and combining with the data of stable isotope in present. They are;1) upper mantle differentiataion type; 2 ) continental crustal anamelting-remelting type; 3 ) continental metasomatic type. An overwhelming majority of the Mesozoic granites in South China is related to rare elementes and nonferous metals belonging to the continental crustal anamelting-remelting type. As the depth of sources, the degree of remelting, the composition of original material, the emplacement mechanism are difference. They can be subdivided into three evolution series, 1) Nanling evolution series] 2) Yangzi evolution series] 3) Minyue evolution series. Each of the three series has its properties. It is incomplete that if we shuld not consider the magmatic evolution law when we make a classification of granitoid in South China.
