地壳构造的

Incorporating lithospheric mantle effect into isostasy model, we analyzed the isostasy state of 20 tectonic units in China continent.

本文基于岩石圈尺度的质量平衡模型研究了中国大陆20个构造单元地壳及地幔岩石圈对地形海拔的贡献，以及各块体的均衡状态。

In central Himalaya, massif was mainly uplifted in the tectonic model of channel flow during 17~7 Ma at a velocity of ~2 mm/a, then was extruded to earth surface at a much lower velocity. In eastern Himalaya Syntaxis, massif was mainly uplifted in the structural style of titling at a background of isostasy since 4.0~2.2 Ma.

喜马拉雅中段主要在17~7 Ma前以通道流的方式快速隆升，之后的抬升过程相对缓慢；东喜马拉雅构造结则主要在3 Ma以来，以地壳均衡作用为背景的掀斜式抬升为主要隆升模式。

There are two prevailing models for the lithospheric thinning of the North China craton:(1) delamination,(2) thermal erosion and chemical metasomatism.

底侵玄武质岩浆的加热并弱化先前的冷和强的克拉通地壳，创造一个流变学条件，以使收缩构造变形和陆壳加厚成为可能。

During the period from Devonian to early Carboniferous,the eastern and western Junggar around Junggar Basin as well as the norther Tianshan area experienced diversification of tectonic settings, and was the period when the deep-crust activities in northern Xinjiang were the most active, and the processes of magmatism and mineralization were most intensive.

从泥盆纪至早石炭世的克拉通化早期阶段，准噶尔周边的东、西准噶尔和北天山地区构造环境变化多样，是新疆北部地壳深部作用最活跃、岩浆作用及成矿作用最强烈的阶段。

The research results imply that the regional tectonic stress field has resulted in deformation and flow of upper mantle material with clockwise rotation,and make the alignment of upper mantle peridotite lattice parallel to the direction of material deformation. The deformation of the crust and upper mantle is possibly vertically coherent deformation.

研究表明青藏高原东北缘上地幔物质在区域构造应力场的作用下，发生了顺时针旋转的形变以至流动，使得上地幔中橄榄岩的晶格排列方向平行于物质形变或流动方向，上地幔变形和上覆地壳变形可能存在垂直连贯变形特征。

The circum-Pacifictectonic system is the subduction zone of oceanic crust. The reverse faults illuminate the compressive stress state.

环太平洋构造系是大洋地壳的收敛地区，逆冲为主的地震破裂显示了该区域以挤压为主的应力状态。

Thirdly, they migrate to a certain direction. Asthenosphere movement leads to the movement of depression-uplift structure. Crustal surface shows undulatory movement due to the asthenosphere. Deformation and movement law of depression-uplift structure accordingly develops.

坳陷构造运动的动力是软流圈运动的结果，软流圈作波动运动使地壳表层也作波动运动，并形成相应的坳隆构造变形和运动规律。

The Earth crust activity of different geotectonic elements could be estimated with the fracture fractal dimension.

利用断裂尺度分布的分形维数值的大小，可以定性判断不同大地构造单元的地壳稳定性。

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
