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。

The leucogranites veins occurred widespreadly in the para-metamorphic rocks, in which the hypersthene melagranulite distributed. That suggests the source rocks of leucogranites of the High Himalaya are para-metamorphic rocks. For the basement was uplifting, pressure relieved and lacked water, source rocks were melting partly and formed the leucogranite magma.

基底副变质岩中广泛分布淡色花岗岩脉体,在基底副变质岩中的淡色花岗岩脉体中发现紫苏辉石暗色麻粒岩残留体,这表明本区高喜马拉雅淡色花岗岩源岩为基底副变质岩,且基底副变质岩是在基底快速隆升降压的条件下发生缺水熔融生成的淡色花岗岩岩浆。

The basal continental crust of Tarim-Tianshan area in Xinjiang consists of the continental nucleus, which is composed of grey gneisses, greenstones, and potass granites similar to charnockites, and its accretionary belts mainly of the early Proterozoic and partly the Middle Proterozoic.

塔里木-天山地区基底陆壳由太古宙灰色片麻岩、绿岩和可能是紫苏花岗岩的含钾花岗岩类组成的陆核及其古元古代和少量中元古代增生带组成。

According to the research of the genetic texture of zircons and SHRIMP dating in the Caledonian banded - augen granitin Yunkai area and the Indosinian charnokite in southeast Guangxi,It is discoved that the ages of later Mesoproterzoic Sibao orogeny event concentrates between 1100 and 950Ma. It provides the important evidenve for the convergent and collision of Rodinan supercontinent in South China and the south extending of Jiangshan-shaoxin collision belt in later Mesoproterzoic.

云开地区加里东期条带-眼球状花岗岩,以及桂东南印支期紫苏花岗岩中锆石的成因结构和离子探针定年研究发现,中元古末四堡造山作用事件年龄集中分布于950-1100Ma,为华南中元古末罗迪尼亚超大陆聚合碰撞造山和江绍带的南延提供了重要证据。

The banded-augengranitic complex(476-413Ma) and charnokites (435Ma) in Yunkai upwelling area are formed in active continental margin Volcanic arc tectonic environment of subduction-collision in Caledonian and the augen granite and charnokiteare formed in the post-orogeny environment,and the intrusive gabbro(392Ma) are fromed in extensional environment of the end of Subduction-collision orogeny.

云开隆起区条带-眼球状花岗质杂岩(467-413Ma)及紫苏花岗岩(435Ma)形成于加里东期俯冲-碰撞活动大陆边缘火山弧构造环境,其中眼球状花岗岩、紫苏花岗岩形成于碰撞造山后环境,侵入辉长岩(392Ma)则是俯冲-碰撞造山作用阶段结束伸展环境下的产物。
