地壳

In some way, the nature of the geochemical field shows that the deep fluid took part in the energy mineral reservoir formation and mineralization.2、 In zones with the strong tectonic activity and basement faults, the elements combination of petroleum is complex and the material from deep resource can be found in which. The character of elements geochemical and carbon isotope all show that there are deep fluid components in some Energy Minerals. The material source of the water accompanying with petroleum reservoir is complex, and which with multi-sources. The character of elements geochemical shows that the uranium of Dongsheng uran ore comes from the upper crust, the greyish-green gritstone and hoary kaolinised argillaceous siltstone is important for the formation of uranium deposits,and the grey gritstone is great potential to surveying uranium deposits .

基底断裂带和构造活动强的区域，原油中元素组合复杂，并含有深源物质；元素地球化学特征和同位素特征反映部分能源矿产中含有深部流体成分；盆地内油气藏伴生水的物质来源较为复杂，具有多源性；元素地球化学特征显示东胜铀矿的铀源主要来自上地壳，灰白色高岭土化泥质粉砂岩及灰绿色粗砂岩对铀矿的形成具有重要的意义，灰色粗砂岩具有良好的找矿潜力；元素地球化学特征还表明，黑岱沟煤及煤层夹矸中微量元素来源于上地壳。

In this paper, the analysis model of crustal vertical movement is established based on the hypothesis of the global flux isostatic datum, and its harmonic function series solution is proposed.

根据全球通量均衡假说建立了地壳垂直形变场的分析模型，在球面近似下求得了该模型的球谐函数级数解并拟合了两个不同区域的地壳垂直形变场，编绘了等值线图，继而在密切平面坐标系下导出了该模型的Fourier级数解。

Meanwhile, they show high abundances of Sr and Ba and high Sr/Y and La/Yb. The volcanic rocks have varied and enriched Nd isotopic compositions ε(subscript Nd=-11~-17, which plot intermediately between the field of the ancient continental crust and the field of the enriched subcontinental lithospheric mantle. These geochemical signatures indicate that the volcanic rocks of the Tiaojishan and Donglingtai Formations were originated from a process of hybridization between the enriched mantle-derived mafic magma and the lower continental crust.

火山岩的钕同位素成分变化大，且相当富集ε(下标 Nd=-11~-17，都分布在古老下地壳和富集地幔之间，因此推断北京西山地区髫髻山组火山岩和东岭台组火山岩的形成与富集地幔起源的基性岩浆与古老下地壳组分相互作用有关。

Pratt hypothesis: A model of compensation for isostasy in which topographically high areas are compensated by lower-density crustal material.

普拉特假说：认为地形高的区域可由其地壳物质的低密度来补偿的一种地壳均衡模型。

The conception of crustal isostasy produces a great effect to the geo-scientific research; especially take an important role in the studies of Geodesy and Geodynamics.

地壳均衡的概念对地学的研究有着极大的影响，特别是在大地测量学和地球动力学中发挥了重要作用。均衡重力大地水准面异常作为研究海底地形、地壳结构、构造及地震活动的重要手段，已被科学家广泛应用。

Airy Hypothesis: A mode of compensation for isostasy in which topographically elevated areas are compensated by underlying "roots" of crustal material penetrating into the higher density subcrust.

艾里假说：地壳均衡补偿的一种模式，认为地形升高的区域可由它下面扎入更高密度地壳物质形成的"根"来补偿。

Isostasy: The gravitational balance of large portions of the earth's crust as though they were floating on a denser underlying layer; it thus accounts for major topography.

地壳大部分处于重力均衡，它们好象是漂浮在下伏致密层(软地壳均衡说：流层)上一样；可用来对主要地形做出解释。

Not only geodetic deformation are in non homogeneity for the space time distribution,but also deformation fields are in macroscopic similarity for the identical time interval.The inherited tectonic movement is a total tendency of recent crustal movement,and the m...

地壳运动过程中存在着区域应变能积累阶段和释放调整阶段，这可能是地震活动的相对平静与活跃的动力机制。1991年以来的地壳运动趋势分析，对判断该区域的应力状态和地震大形势具有一定的参考意义。

While in fact the central latitude fault of Tarim eventually was deeply cut by the northwestward movement, which pushed blocks on east of 82°to north at a distance of 50km. This discovery will be greatly helpful in the researches on the basement tectonic of Tarim basin.

利用地球物理研究地壳的深部构造，不仅为地壳的演化和大陆的形成等基础理论问题的深入研究提供证据，而且对划分大地构造单元、分析和预报天然地震的活动性以及研究各种矿产的成矿规律也具有十分重要的指导意义。

The rock is peridotite, which is one of the main rocks in the upper mantle, an area that provides a girth below the Earth's crust.

这种石头是一种橄榄岩，是上地幔中的一种主要岩石。地幔位于地壳下面，包围着地壳。

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。
