查询词典 xenoliths

Some geologists,however,on the basis of observations concerning mantle xenoliths,argue that the mantle is not layered,but that heterogeneity is created by fluids rich in "incompatible elements"(elements tending toward liquid rather than solid state)percolating upward and transforming portions of the upper mantle irregularly,according to the vagaries of the fluids'pathways.

但是，某些地质学家，以对地幔捕虏岩体所作的观察为依据，指出地幔并非是分层排列的，相反，地幔的异质性是由那些富含&不相容成分&的流质构成的，这些成分趋向於流体而非固体的状态，自下而上渗透扩散，并依照这些流质流向的任意性，不规则地将上部地幔的某些部分予以改变。

Therewere many mantle lherzolites xenoliths and huge xenocrysts in these basalts.

我们首次对这些幔源包体和高压巨晶的氦同位素组成进行了系统的研究。

The helium isotope results of nodules in C-CZone, eclogite in Dabie-Sulu region and mantle xenoliths and xenocrysts in Cenozoic basalt ineastern China were reported in this thesis.

本文重点介绍了C-C区海底多金属结核、大别山榴辉岩和中国东部新生代玄武岩中幔源包体的氦同位素研究成果。

The Cenozoic lithospheric mantle beneath the western Qinling was refractory in major element compositions based on the mineral compositions of xenoliths and xenocrysts and experienced complicated deep processes.

地幔捕虏体和捕虏晶的地球化学特征表明西秦岭新生代岩石圈地幔具有难熔的特征，并经历了复杂的深部过程。

The mantlelherzolites xenoliths with lower ~3He/~4He ratios may be from upper metasomatic enriched mantleand the garnet xenocrysts may be from below extra-depleted mantle formed by metasomatism.

具有异常低~3He／~4He比值的幔源包体可能来自上部交代富集型地幔源区；具有较高~3He／~4He比值的高压巨晶可能来自下部极度亏损地幔源区。

Peridotite xenoliths from Nüshan, Hannuoba and the Subei basin of the North China block have much lower water contents than those from other localities of the world (South Africa craton, New Mexico, Colorado plateau and basin and Range province of USA, South Mexico, French Central Massif and West Kettle of Canada). This difference is probably induced by the thermal erosion of asthenosphere during Mesozoic-Cenozoic period in the North China block.

结合已经发表的安徽女山和河北汉诺坝的橄榄岩数据，对比世界上其他地区橄榄岩的数据来看，华北的岩石圈地幔具有低的水含量：华北橄榄岩的单斜辉石水含量多＜200×10^(-6)，而世界上其他地区（包括南非克拉通、美国新墨西哥地区、美国Colorado高原、美国盆岭省地区、墨西哥南部、法国中央地体以及加拿大West Kettle地区）橄榄岩的单斜辉石水含量多＞200×10^(-6)；华北的斜方辉石水含量多＜100×10^(-6)，而世界上其他地区多＞100×10^(-6)；华北的橄榄岩全岩水含量多＜50×10^(-6)，而世界上其他地区多＞100×10^(-6)。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
