长英麻粒岩

The contents of Ni, Au, Mo, W of the deep-seated xenoliths and their host basalts from eastern China are inhomogeneous. The contents of Ni, Au are highest in the mantle-derived xenoliths the contents of Mo, W are highest in the basalts and the mafic granulite, and the leptite and the granitoids, respectively.

These results indicate that both the second type leucosome in the biotite gneisses and the first type leucosome were produced synchronously in the Paleoproterozoic granulite-facies metamorphism, and that both the melt-derived and the metamorphic Paleoproterozoic zircons suffered significant lead-loss in the Triaasic, suggesting that both felsic granulite and biotite gneisses be responses to the Triassic deep subduction event.

这表明，第二类浅色体和第一类浅色体都是古元古代麻粒岩相变质作用同期深熔产物。古元古代熔体结晶和变质结晶锆石在三迭纪发生了严重的放射性成因铅丢失，可反映长英质麻粒岩和黑云母片麻岩都响应了三迭纪深俯冲事件。

The geochemistry and isotopic characteristics of the three xenolith groups vary systematically from group to group.

对各种深源岩石捕掳体的地球化学和Sr-Nd同位素组成分析表明，总体上，麻粒岩类捕掳体呈现富集特点，从二辉麻粒岩到长英质麻粒岩的系统变化指示了壳幔混合作用的存在。

The straight gneisses have the plane-straight gneissic; beating a few, fine and plane-straight felsic streaks; the mineral stretching lineation; as the S-L tectonite with the features of finer mineral grain size (1mm±), uniform grain size grade and bad directional, showing the ultra-plastic flow mechanism.

强直片麻岩发育平直的片麻理，长英质条带含量相对较低，但细而平直，发育矿物拉伸线理，为S-L构造岩，矿物粒度相对较细(1mm±)，粒级均匀，定向性差，均反映出强直片麻岩的超塑性流动变形机制特征。

The eclogites at western segment of Altyn Tagh tectonic belt occur as lens or boundins within quratz-feldspathic gniesses characterized by amphibolite-facies parageneses. It mainly experienced the prograde amphibolite-facies stage (P=6.06-8.70kb, t=615-690℃),peak eclogite-facies stage (P＞15kb,T=700-850℃), granulitic facies stage (P=11-14kb,T=750℃) and ampbiolite-facies stage (P=6.3-9.5kb,T=619-738℃) during decompression.

阿尔金构造带西段的榴辉岩呈透镜状产于长英质片麻岩中，它主要经历了进变质的角闪岩相(P=6.04-8.70Kb，T=615-690℃)、峰期的榴辉岩相(P＞15Kb，T=700-850℃)及减压过程中的麻粒岩相(P=11-14Kb，T=750℃)及角闪岩相(P=6.3-9.5，T=619-738℃)的变质作用，构成一个顺时针的PT轨迹。

The khondalite series within Kongling Group in Yichang City, Hubei Province are composed of aluminum-rich schists-gneisses and garnet-sillimanite-quartzites, leptynite and mafic granulites, its protoliths are clay, sandstones-greywacke and marlite. REE distribution patterns of aluminum-rich gneisses incline NASC, Eu show negative abnormity and Ce displays no abnormity in chondrite-normalized REE distribution patterns.

湖北宜昌崆岭群孔兹岩系由富铝片岩－片麻岩及榴线英岩类、长英质岩类及镁铁质麻粒岩类组成，其原岩分别为黏土岩、砂岩－杂砂岩和泥灰岩，富铝片麻岩的稀土元素分配型式接近北美页岩组合样，Eu显示负异常，而Ce基本无异常。

According to their mineral assemblages, the granulite xenoliths entrained by Cenozoic Hannuoba basalts are divided into four groups: felsic granulites, noritic granulites, two-pyroxene two-feldspar granulites and two-pyroxene granulites, with the two-pyroxene granulites most common.

根据矿物组合特征，汉诺坝玄武岩中的麻粒岩捕掳体可划分为四种类型：长英质麻粒岩、苏长质麻粒岩、二辉二长麻粒岩和二辉麻粒岩，其中以二辉麻粒岩最为常见。

The deep-seated xenoliths entrained by the Cenozoic Hannuoba basalts can be divided into three groups according to their mineral assemblages:Ⅰ Granulites, including felsic granulites, noritic granulites, and dominantly, two-pyroxene granulites,Ⅱ Pyroxenites, including websterites, spinel pyroxenites, and garnet pyroxenites;Ⅲ Peridotites, including spinel lherzolites and spinelgarnet lherzolites.

根据新生代汉诺坝玄武岩中深源岩石捕掳体的矿物组合类型，将其分为主要的三大类：麻粒岩类中包括长英质麻粒岩、苏长质麻粒岩和二辉麻粒岩，辉石岩类包括二辉石岩、尖晶石辉石岩和石榴子石辉石岩，橄榄岩类则包括尖晶石二辉橄榄岩和尖晶石-石榴子石二辉橄榄岩。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
