| 英文摘要 | Lithium concentrations and isotopic compositions of 39 A-type granites and mafic enclaves from 11 plutons in Northeast China and the North China craton are used to constrain their genesis and to characterize further the average composition of the continental crust. Lithium concentrations (2.8 to 80 ppm) in 29 A-type granites are slightly higher than those of average I-type granites and lower than those of average S-type granites, reflecting source differences. Lithium isotopic compositions (delta(7)Li = -1.8 to +6.9) of A-type granites fall within the range of worldwide I-type and S-type granites. By contrast, 10 mafic enclaves have significantly higher Li concentrations (32 to 179 ppm) and less variation in Li isotopic compositions (delta(7)Li = -3.2 to +3.1) than their corresponding granites, due to the high modal abundance of amphiboles and biotites. Overall, the weighted mean delta(7)Li for A-type granites, as well as I-type and S-type granites is lighter than that of the mantle. |
