本文讨论了出露在大兴安岭主峰穹状复背斜核部的变质核杂岩。从岩石组合、变质温压条件、变形特征角度阐明了变质核杂岩的结构。从变质核杂岩各层之间的产状关系进一步探讨了变质核杂岩隆升时间以及与大兴安岭隆升的关系。最后通过核部侵位的超镁铁－镁铁质岩探讨了变质核杂岩隆升的深部背景。
This article discusses the metamorphic core complexes exposed in the core anticlinorium of the main peak of the Greater Xing’an Mountains. The structure of metamorphic core complexes is elucidated from the aspects of rock assemblage, metamorphic thermo-compression conditions and deformation features. The relationship between the uplifting time of metamorphic core complexes and the uplifting of Daxinganling was further discussed from the relationship between the metamorphic core layers. Finally, the deep background of the uplifting of metamorphic core complexes is discussed by the ultramafic-mafic rocks invaded by the core.
