Abstract
Granitoids are widely spread in the Nanling Region of China. Four rockbodies in the region have been studied for their REE, Rb, Sr, Ba and Sc distributions. The four rockbodies occurred in different locations and are characterized as being different in age and type. The rock types are presented as follows: Qinghu monzonite, Guangxi; Fuxi granodiorite, Guangdong: Jiufeng monzonitic granite, Hunan; Zudong K-feldspar granite, Jiangxi. From the major and trace element distributions in these granitoids it is dearly shown that Rb/Sr ratios in the rocks tend to increase with increasing SiO2, content and differentiation index (DI), but LREE/HREE, La/Yb and K/Rb ratios tend to decrease, suggesting a correlation between trace element distribution and major element composition for the granitoids. The distribution characteristics of trace elements in each of the rockbodies are described in detail. From the comparative analysis of the Qinghu monzonite and Fuxi granodiorite it is evidenced that the REE distribution is closely related to the sequence of crystallization for the minerals, and also to the petrochemical types of these granitoids in addition to their crystal chemistry.
