| 摘 要： | 中国花岗岩类的出露面积，约占我国陆地总面积的10％。依据12265个样品求出中国花岗岩类的总平均化学成分；并结合Daly，Nockolds和Beyc等花岗岩类样品，近似地求出世界花岗岩类的总平均化学成分。以此为背景，显示出中国花岗岩类富SiO2、Na2O和K2O的区域特征。

| Abstract: | 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. |
