查询词典 crust

The petrochemistry and geochemistry of Mesozoic volcanic rocks mainly indicate the environmental characteristic of distending structure which bears on orogenic belt. The process of the evolution that earth crust keeps thinning reflects that it is still in the time of extruding orogenesis. Only during the intermittence or relaxation stages of extruding orogenesis, the volcanic eruption of neutral rock and acidic rock were formed in the situation of relative distending structure.

中生代火山岩的岩石化学、地球化学特点，主要显示了与造山带有关的拉张构造环境特征，而地壳由薄变厚的演化过程，则反映了该时期仍以挤压造山作用为主，只是在挤压造山作用的间歇或松驰阶段，相对处于拉张构造环境的情况下，形成了中酸性岩的火山喷发。

Hutuo group of greenschist facies of the mainly sedimentary rocks appears a tectonic style of the huge invert-fan synclinorium in Wutaishan, illustrates the material components of the above crust and inner continental orogenesis.

Recent progresses show that the widely distributed ductile flow in the lower crust is one of the most important constraints in orogeny.

最近的研究表明，下地壳普遍存在的韧性流是造山作用的重要制约因素。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

东莫扎抓铅锌矿床矿体呈似层状展布，产状严格受到矿区逆冲断层的控制，赋矿围岩为上三叠统结扎群波里拉组灰岩和下-中二叠统开心岭群尕迪考组灰岩，发育强白云石化和弱硅化，矿物组合简单，主要为闪锌矿+方铅矿+黄铁矿+白云石+方解石+重晶石，矿石结构以皮壳状、草莓状等胶状结构和他形粒状结构为主，矿石构造为浸染状、角砾状、团块状和脉状。

The early stage of me tamorphism happened before deformation in the upper mantle at about 60-70km. Then metagabbro emplaced rapidly at about 40 km by diapirism and perhaps amalgamated with cool subducted oceanic crust. After that, rapid cooling retrograde metam orphism occurred. Early rapid ocean spreading was constrained because subduction appeared. Therefore, metagabbro continued to uplift under the slow extension. At last, it obducted and thrusted to outcrop on the surface.

变形前的早期变质可能发生在60～70km处的上地幔，然后变质辉长岩快速"底辟"构造侵位，上升至约40km深处，可能与俯冲的冷洋壳并置，发生快速降温退变反应；因俯冲作用的开始，抑制了洋盆快速扩张，变质辉长岩在减速伸展环境下继续抬升减压；后期又由于仰冲推覆，最终出露地表。

The outermost layer, the part we see on the surface of the earth, is the crust.

最外面的一层，也就是我们在地表所看到的，是地壳。

We live on the thin outermost layer called the crust, which is formed by cooled solid rocks.

我们生活在最外面那层薄薄的地壳上，它是由冷却的固态岩石构成的。

The heat flow piercement,magma house in crust and volcanic rock overlap in space. The distribution of inorganic carbon dioxide reservoirs relates to above three gas resources. The outgas models of the heat flow piercement and volcano-magma are the main models of gas resources in Songliao Basin.

松辽盆地热流底辟体、壳内岩浆房和火山岩在空间上叠置，且已发现的无机二氧化碳气富集区与这三者密切相关，表明热流底辟体脱气模式和火山—岩浆成因模式是无机成因气主要的"气源"模式。

Europa's fractured icy surface is thought to overlie an ocean about 100 kilometers (60 miles) below the surface, and the New Horizons team will be analyzing these images for clues about the nature of the icy crust and the forces that have deformed it.

木卫二的典型冰封表面被认为是躺在100千米冰层下的海洋上，"新视野"的小组将分析这些图片寻找冰盖特性的线索以及使其变形的力量。

By comprehensively using the information of lithostratigraphy, paleobiology, isotope, paleomagnetism, fission track of apatite, well-logging, geophysics and petroleum geology, the characteristics of the sedimentary wave processes in the Tazhong uplift, North depression and the Tabei uplift were studied by the wave process analysis method under the direction of the wave theory of the earth's crust movement in this paper, and the main achievements are as follows

本文以地壳波状运动理论为指导，综合利用岩石地层、古生物、同位素、古地磁、磷灰石裂变径迹、测井、地球物理、石油地质等方面的资料，运用沉积波动过程的研究方法，研究了塔里木盆地环满加尔地区(塔中隆起带，北部坳陷和塔北隆起)的沉积波动特征。

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。
