摘要
///The intrusive rock located in the eastern part of Xiemisitai, Xingjiang, was identified as A-type granites. The chemical compositions of the intrusions are characterized by high-Si, A/CNK 0.88 to 0.98 range and the Rittmann Index σ in between 2.44 to 5.90. The REE pattern is characterized by rightward declined "Seagull" shaped curves, rich in LREE and strong negative Eu anomalies.
