地壳

An instance of agitation of the earth's crust .

地壳的一次搅动情况。

The airgun signal was detected all along the line of the largest offset equal to 185 km, seismic phases Pg, Pc, P2, PmP and Pn have been picked successfully, based on which 1-D forward modeling of deep crustal structure has been conducted and the low-velocity layer of crust-mantle transition zone has been discussed.

在185km长的测线上均记录到了气枪信号，成功检测到Pg，Pc，P2，PmP和Pn等多组震相，并在此基础上对地下深地壳结构进行了一维速度结构正演，讨论了该区域壳幔过渡带的低速结构。

This project also compared and discussed the research results of OBS and onshore-offshore experiments in nearby areas. The conclusion is that the active airgun source is equivalent to an earthquake of about magnitude 0.5, and the airgun signals can be detected at the maximum distance of only about 250 km, which is not enough for the study of deeper lithospheric structure below the crust. Furthermore, the onboard airgun source and MCS streamer are difficult to operate in the shallow water of reef and island areas.

本项目还分析对比了周边地区海底地震仪探测和海陆联合地震探测的研究成果，发现人工气枪震源约相当于0.5级的天然地震，其信号传播距离最远只有250 km左右，很难探测到地壳以下更深部的岩石圈结构特征，此外船载的气枪震源和多道电缆在岛礁区和浅水区很难开展工作。

Geothermal gradients of the basins in the eastern of Algin Rift were higher than those of the basins in western of Algin Rift in Late Mesozoic,and tectonic activities were stronger,indicating a strong regional tectonic thermal event.The basins on the western of Algin Rift were all compressive depressions,their geothermal gradients were lower.

中生代晚期阿尔金断裂以东沉积盆地地温梯度普遍高于阿尔金断裂以西沉积盆地，构造活动性强，强烈的构造运动引发了岩浆活动及地壳深部热活动，表明存在一期强烈的具有区域规模的构造热事件；阿尔金断裂以西为挤压坳陷型盆地，地温梯度普遍较低。

The altiplano which you had been to years ago was just sleeping under the lithosphere.

你在多年前登过的高原，如今沉睡在地壳的深处。

Deformation experiment of amphibole shows that ,under conditions of pressure that is similar to the depth at which crustal low velocity layer of the Qinghai Xizang plateau is buried (20 30 km), and temperature heated to 800℃and 1000℃,amphibolite undergoes plastic deformation and enters steady creep strain states.

在相当于青海—西藏高原地壳低速层埋藏深度（20 ～30 km）的压力条件下进行了角闪岩的变形实验。实验表明，当加热到800℃、1000 ℃时，角闪岩出现塑性变形，并进入稳定蠕动应变状态。

Based on these results, we analyzed seismic activity along subsurface faults and within crust, lateral variations of velocity anomalies at different depths and their relations with geological tectonics, crustal anisotropy of the mantle anomalous area beneath the west Tien Shan and possible dynamic mechanism.

以此为基础，我们分析了浅表层断裂和地壳深部的构造活动、不同深度速度异常的横向变化与重要地质构造的关系、天山西部地幔异常区地壳深部的各向异性特征和可能的深部动力机制等。

Overall, crustal thickness peaks in the Tibetan Plateau, decreasing in Tien Shan and its surrounding areas and thinning out in Southern China even thinner.

总体上看。青藏高原地区的地壳厚度最大，天山、准格尔盆地、内蒙古大部地区次之，中国华南沿海一带地壳厚度更小。

Since the Dabie orogenic belt was affected meanwhile by the delamination of post collision of Indo-Chinese epoch and the subduction toward EuraAsia continent of Izanagi plate, the upwelling of asthenosphere material supplied a lot thermal energy for crust, isobathythem ascented, this made middle and lower crust amphibolite and granulite facies metamorphic and large-scale free water-bearing system and large area migmatites and granites were formed.

在大别造山带印支期碰撞后所产生的拆沉作用和伊佐奈崎板块向欧亚板块的NWW向俯冲作用的共同影响下，软流圈物质上涌，为地壳输送大量的热能，等温面上升，使中下地壳发生角闪岩相或麻粒岩相变质作用和大规模含自由水体系的熔融，形成了大面积混合岩和花岗岩。

It′s crusts can be described as three-layer structure. The average thickness of upper crust is 20km, but that of Qaidam Basin and Bayanhar Terrane are thicker to 20km, and that of Jinsha Suture and Eastren Kulun Fault are thinner to 12km.

地壳基本上属于三分结构，上地壳平均厚1 5公里，柴达木盆地和巴颜喀拉地区稍厚，平均20公里，三江地区和东昆仑较薄，平均厚12公里。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
