| Abstract: | 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. |
