Confirmation and Preliminary Study of Aluminous A-Type Granites in the Wuyi Mountain Area, Eastern Jiangxi Province, China
摘要
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 P2O5. The granites are enriched in REE (∑REE = 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.关键词
