对天山东段尾亚麻粒岩的稀土元素和Ｓｍ－Ｎｄ同位素特征的研究表明，其原岩为１８－２０亿年地幔分异的产物，为具有岛弧特征的钙碱性岩系，以轻稀土富集为特征。并且讨论了麻粒岩原岩的形成，为交代地幔较大程度部分熔融的产物。岩浆形成和侵位过程中，有地壳物质不同程度的混染。
The study of the REE and Sm-Nd isotopic characteristics of the Tailian granulite in the eastern Tianshan Mountains shows that the protolith is a product of mantle differentiation between 1.8 and 2.0 billion years and is a calc-alkaline rock series with island arc characteristics. Rare earth enrichment is characterized. The formation of granulite protoliths is also discussed and is a product of the greater degree of partial melting of the mantle. Magmatic formation and emplacement process, the crust of varying degrees of contamination.
