| Abstract: | The average chemical composition of granitoids in 17 diwa regions are calculated with their 12 126 samples.Their geotectono－ petrochemical types and regional petrochemical characteristics are discussed detailed by the analitic method of their association of enriched major elements.Their regional differences and their several regularities of distribution,and the speciality of granitoids in the NS diwa region are also paid attention. |
