长英片麻岩

在野外1∶10000地质填图及室内研究工作基础上，认为夹皮沟地区太古代主体岩石是中酸性侵入体（TTG），已变质成为长英质片麻岩。

According to field geological mapping ( scale 1:10000 ) and comprehensive study in laboratory , the major archaeozoic rocks are intermediate-acid intrusives , which were metamorphosed into the felsic gneisses .

榴辉岩的主体围岩是长英质片麻岩，它与榴辉岩不是相同高压变质作用的产物。

Both the eclogite and the felsic gneiss have not undergone the same high-pressure metamorphic event .

这些岩石的角闪岩相退变质产物分别是斜长角闪岩、蛇纹岩、长英质片麻岩、长石石英云母片岩、石英岩和大理岩。

They were transformed to amphibolite , serpentinite , gneiss , quartz-mica schist , quartzite and marble during the amphibolite-facies retrogression .

在东喜马拉雅构造结南迦巴瓦岩群中，石榴辉石岩呈透镜状产于麻粒岩相变质的长英质片麻岩和泥质片岩之中。

Garnet pyroxenite occurs as lenses in granulite-facies metamorphic granitic gneiss and pelitic schist in the Namjagbarwa Group-complex of the eastern Himalayan tectonic syntaxis .

要加强对长英质片麻岩中原生结构、包体、副矿物（特别是锆石）和地球化学的研究。

It is very important to strengthen the study of the primary texture , enclaves , accessory minerals ( especially zircon ) and geochemistry .

在东南极普里兹湾拉斯曼丘陵地区变泥质岩和长英质片麻岩中，定向分布着透镜状、扁豆状和香肠状镁铁质、超镁铁质麻粒岩。

Oriented distributed mafic granulite lenses , pods and boudins occur in metapelitic and leucogneiss in the Larsemann Hills , Prydz Bay , East Antarctica .

要特别注意不同成因长英质片麻岩之间和它们与其他围岩之间接触关系的研究。

Special attention should be given to the study of the contact relationships between felsic gneisses of different origins and between them and other country rocks .

长石石英云母片岩、石英岩和大理岩的原岩为沉积岩，与副变质的长英质片麻岩和基性火山岩一起构成了古老的表壳岩组合。

The quartz-mica schist , quartzite and marble were metamorphosed sedimentary rocks , and , together with paragneiss and mafic rock , constituted the old supracrustal series .
