南极儒尔群岛太古宙地块高级变质地体岩石记录了区域重要的地壳演化历史。通过对该区开展同位素地质年代学、岩石地球化学和同位素地球化学研究，确定该区太古宙岩石的年代格架、原岩性质和构造环境；联合锆石的Hf-O同位素和U-Pb定年分析，揭示隐藏在锆石颗粒中记录地壳生长和演化历史的"指纹"密码，约束正片麻岩和表壳岩的形成时代、变质时代和岩石的源区性质。重点研究区内古太古代（3470-3270 Ma）和中太古代晚期（2840-2800 Ma）两期英云闪长质正片麻岩等岩石的地球化学特征，结合锆石的稳定和放射性同位素研究，探讨它们形成的构造环境，进而恢复太古宙该区构造环境的特征及其演变的过程，为南极大陆太古宙地壳形成及演化提供新的地球化学制约。结合东南极及其他陆块的地质特征，探讨区域地壳组成、形成和演化以及源区性质。该项工作对太古宙全球构造演化的研究具有重要的科学意义。

Archean granulite-facies rocks in the Rauer Group, Antarctica, represent important suites of rocks exposures for investigating the development of high-grade metamorphic terrains in East Antarctica. Zircon grains from various rocks covering the Rauer Group will be analysed for U-Pb ages, Hf-O isotopes, and trace elements, using in situ SHRIMP IIe and LAM-ICPMS techniques, to evaluate the terrane-scale crustal evolution, and for the correlation of terranes. U-Pb age are used to estimate the timing of terrane-scale events, primarily magmatic and metamorphic episodes; Hf and O isotopes provide information on the relative contributions of juvenlie material and reworked older crust at each stage of crustal evolution; trace-element patterns of zircons are used to characterise original magma types. Special for Archaean two episodes tonalitic orthogneiss (3470-3270 Ma and 2840-2800 Ma), the analysis of such populations sampled in these rocks generates U-Pb ages that can be used to date fundamental terrane-scale events-magmatic episodes, metamorphism events. The study will provide an important temporal framework for the correlation of other parts of a complex mosaic of metamorphic terraness from East Antarctica. The new data are to be encourage revised models for global Archean crustal evolution.
