紫苏辉石的

The results show that, Main crystallization phase of glass ceramic was hedenbergite, and the minor crystallization phases were augite and hypersthene. With increasing boron mud addition, the amount and the size of crystallization phases both gradually increased, the configure of crystallization phases transformed from the branch, the ball, to the block. The transformation from the branch to the ball could improve the properties of glass ceramic, and the transformation from the ball to the block could worsen the properties of glass ceramic.

结果表明：矿渣微晶玻璃的主析晶相为钙铁辉石，次晶相为普通辉石和紫苏辉石；随着硼泥配入量的增加，矿渣微晶玻璃中晶体的析出量和尺寸均逐渐增加，晶体形态由枝晶向球晶及块状晶体过渡；枝晶向球晶转变可以明显改善矿渣微晶玻璃的性能，而球晶向块状晶体的转变则恶化了微晶玻璃的性能。

The turbidite sandstones in the study area can be classified at least into six types based on the combination of the quantitatively major heavy minerals such as opaque minerals, hornblende, hypersthene, and augite.

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 formation and evolution of magma have experienced three stages:① thermal fluid led to higher partial melting of lithosphere mantle and then formed hypoalkaline basalt with saturated initial sulfur when ascending asthenosphere contacted with the lithosphere mantle;② the initial magma intruded into the lower crust to form magma chamber, the crystallization of magma produced stratiform-like cumulate, including olivine, hypersthene, augite, magnetite, and then formed residual gabbroic magma with the participance of crustal material;③ the residual magma and ore-bearing cumulate intruded upward successively to shape original mafic complex rocks in Wuxing when the magma chamber cracked.

岩浆形成与演化经历了3个阶段：①上升的软流圈与岩石圈地幔接触，热流体作用导致岩石圈地幔发生高度部分熔融，形成初始硫饱和的次碱性玄武岩；②初始岩浆上侵，在下地壳形成岩浆房，岩浆结晶作用形成以似层状橄榄石、紫苏辉石、普通辉石和磁铁矿等为主的堆晶岩，在地壳物质的参与下形成残余辉长质岩浆；③岩浆房破裂，残余岩浆和含有熔体(0%)的堆晶岩相先后上侵形成五星原始镁铁质杂岩。

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。
