:依据采自全国范围内750个有代表性的大中型花岗岩类岩体上的767件组合样的实测分析数据,本文计算并提出了天山-兴安造山系、中朝准地台、昆仑-祁连-秦岭造山系、滇藏造山系、扬子准地台、华南-右江造山带、喜马拉雅造山带等中国七大构造单元花岗岩类和不同构造单元碱长花岗岩、正长花岗岩、二长花岗岩中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和Y等近70种化学元素和成分的丰度,探讨了不同构造单元花岗岩类岩石的岩石化学特征和微量元素丰度的特征及其区域分布。

Abundances of Chemical Elements of Granitoids in Different Geotectonic Units of China and Their Characteristics

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.
