Widespread in the Wuyi Mountain area of eastern Jiangxi are petrochemically peraluminous granites and they are characterized as being high in silica (SiO-2>75%) and highly alkaline (ALK=6.9%-7.5%) with K-2O>Na-2O and rather high ratios of FeO+T/MgO (11.3-17.9). The rocks have low contents of CaO, MgO, TiO-2 and P-2O-5 . 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×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.
