摘　　要：依据采自全国范围内约750个有代表性的大、中型花岗岩类岩体上的768件组合样的实测分析数据,这里计算并提出了碱长花岗岩、正长花岗岩、二长花岗岩、花岗闪长岩、石英二长岩、石英二长闪长岩等中国不同岩石类型的花岗岩类岩石近七十种化学元素或成份的丰度,探讨了中国不同花岗岩类岩石的岩石化学特征和微量元素丰度的特征。Based on the analysis of 768 composited samples that were collected mainly from about 750 large to middle representative granitoid bodies in nation-wide, the average chemical compositions and element abundances of about 70 chemical elements in different rock types of granitoids in China such as alkalifeldspar granite, syenogranite, adamellite, granodiorite, quartz monzonite and quartz monzodiorite, are calculated and presented in this paper. It is sufficiently discussed on the characteristics of petrochemical parameters, trace element contents and rare earth element distributions of different rock types of the granitoids.
