| Abstract: | On the basis of actual analytical data of 767 composited samples collected mainly from about 750 large to middle representative
granitoid bodies all over China, the average chemical compositions and element abundances of about 70 chemical elements of
SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, Na2O, K2O, H2O+, CO2, TFe2O3, 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 in China such as Tianshan-Xing’an orogenic series, Sino-Korean metaplatform,
Kunlun-Qilian-Qinling orogenic series, Yunnan-Tibet orogenic series, Yangtze metaplatform, South China-Youjiang orogenic zone
and Himalayan orogenic belt, are calculated and presented in this paper. In addition, the characteristics of petrochemical
parameters, trace element contents and rare earth element distributions of different rock types of the granitoids in different
geotectonic units are also sufficiently discussed.
