SHI Changyi,YAN Mingcai,CHI Qinghua Institute of Geophysical and Geochemical Exploration,Langfang,Hebei,065000  
On the basis of actual analytical data of 767 composite samples collected mainly from about 750 large to middle representative granitoid bodies in China,the average chemical compositions and element abundances of about 70 chemical elements of SiO_2,Al_2O_3,Fe_2O_3,FeO,MgO,CaO,Na_2O,K_2O,H_2O+,CO_2,TFe_2O_3,Ag,As,Au,B,Ba,Be,Bi,Cd,Cl,Co,Cr,Cs,Cu,F,Ga,Ge,Hf,Hg,Li,Mn,Mo,Nb,Ni,P,Pb,Rb,S,Sb,Sc,Se,Sn,Sr,Ta,Th,Ti,Tl,U,V,W,Zn,Zr,La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Lu and Y in alkalifeldspar granite,syenogranite and adamellite in 7 geotectonic units of China such as the Tianshan-Xingan orogenic series,Sino-Korean metaplatform,Kunlun-Qilian-Qinling orogenic series,Yunnan-Tibet orogenic series,Yangtze metaplatform,South China-Youjiang orogenic zone and Himalayan orogenic zone,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 granitoids in different geotectonic units.
