Abstract
Widespread in the Wuyi Mountain area of eastern Jiangxi are petrochemically peraluminous granites and they are characterized as being high in silica (SiO2 > 75% ) and highly alkaline (ALK=6.9% -7.5%) with K2O > Na2O and rather high ratios of FeOT/MgO (11.3-17.9). The rocks have low contents of CaO, MgO, TiO2 and P2 O5. The granites are enriched in REE (ΣREE =210.3 - 496. 8 μg/g) with remarkable negative Eu anomalies, but depleted in Eu, Ba, Sr, V, Co, and Ni, with 10000 x Ga/Al ratios, varying from 6. 1 to 9. 8. It is clear that these granites are obviously different from the I- and S-type granites, but are quite similar to those typical A-type granites such as aluminous A-type granites in the coastal areas of Fujian Province.
