Based on the petrological and geochronological study of metamorphic complexes from the Grove Mountains, the following conclusions are reached.(1)Exsolution texture is widely found in clinopyroxene in mafic granulites. A peak metamorphic temperature of 850 C was obtained from the reintegrated compositions of exsolved clinopyroxene. The preservation of augite megacrysts suggests a single episode of high-grade metamorphism for the Grove Mountains.(2)The compositional comparison of garnet from pegmatites with that from country rocks demonstrates that garnet in pegmatites is of xenocryst origin, and late amphibolite facies metamorphism does not occur in this area.(3)The Pan-African charnockite and post-tectonic sheet-like granite were first recognized in East Antarctica. Their occurrences suggest a collisional orogeny during the Pan-African time.(4)The SHRIMP U-Pb zircon dating on various rock types indicates that the major metamorphism in the Grove Mountains occurs at c. 550 Ma, and the tectonothermal evolution terminated at c. 500 Ma. The Grenvillian granulite facies metamorphism did not develop in the studied area.(5)The Prydz belt, the second Pan-African suture within the Gondwana suppercontinent, was further comfirmed based on this study. The Gondwana suppercontinent was not formed by the simply juxtaposition of East and West Gondwana, but by the collision of several blocks during the Pan-African time.

本项目通过格罗夫山地区高级变质杂岩的变质岩石学和同位素年代学研究，获得如下重要认识：（1）发现辉石出溶结构，由此获得峰期变质温度为850 C，并根据火成普通辉石的识别确定该区只存在单相麻粒岩相变质；（2）通过伟晶岩中石榴石斑晶与围岩中石榴石的对比研究提出了石榴石的捕虏晶成因，进而确定该区不存在晚期角闪岩相变质作用；（3）在东南极首次识别出泛非期紫苏花岗岩和后构造层状花岗岩，为泛非构造热事件的碰撞造山成因提供了重要佐证；（4）对不同岩石类型的锆石SHRIMP定年精确地限定了格罗夫山地区主期变质作用发生于泛非期，～550 Ma，热事件结束于～500 Ma，年代学数据没有揭示在该区存在格林威尔期麻粒岩相变质作用的迹象；（5）进一步确认了东南极内部普里兹带的存在，它属于冈瓦纳超大陆内部的第二条泛非期缝合带，据此认为冈瓦纳超大陆并不是由东、西冈瓦纳陆块的简单拼合而成，而是多个不同块体拼合的结果。

SEM and XRD reveal that the CA crystallized film have larger grains and lattice constant of garnet than the RTA crystallized film, which implies that in the CA crystallized film more bismuth ions substitute into the dodecahedral site in the garnet structure.

至于两种薄膜的法拉第旋转峰的偏移，初步认为是由于两种薄膜的石榴石相晶格大小不同，造成晶体场强度的不同，使得与磁光跃迁相关的基态和激发态之间的能量差有所差异。

It was also found that the film of smaller grains corresponded to a smaller lattice constant of the garnet structure, which implied that fewer Bi〓 ions substituted into the dodecahedral sites in the garnet, due to the fact that the smaller grains resulted in more grain boundaries, thus leading to more serious Bi segregation in the grain boundaries.

分析表明，细小的晶粒意味着薄膜中含有更多的晶界，这样将导致Bi组分在晶界上的偏析较显著，而进入石榴石结构中氧十二面体间隙的Bi〓较少，对于Bi，Al∶DyIG来说，石榴石相晶格常数与{Bi〓}〓呈正相关关系，由此可以解释具有细小晶粒的薄膜对应较小的石榴石相晶格常数。
