ON THE AVERAGE CHEMICAL COMPOSITION OF GRANITOIDS IN CHINA AND THE WORLD

LI Tong;YUAN Huayu;WU Shengxi(Department of Geology, University of Science and Technology Beijing, Beijing 100083)  
The exposed area of granitoids in China represents about 10% land area of this country.The total average chemical composition of granitoids in whole China is calculated with 12265 samples. And the total average chemical composition of the world's granitoids is also calculated with their samples adopted from this paper and Daly (1933), Nockolds (1954) and Beyc(1972). As based on the world's background, the regional characteristics of China's granitoids are rich in the contents of SiO2, Na2O and K2O.
