- When, where, how and why does the lower crust of the Qinghai-Tibet plateau flow in the disintegrated lithosphere? 解体的青藏高原岩石圈下地壳何时、何处、如何和为何流动;
- It is postulated that a high conductive body exists in the lower crust or upper mantle. 据此推测在地壳下部或地幔上部存在一高导体。
- By using 3-D gravity forward calculation,we obtained the deep gravity anomalies of Tai-wan from its Bouguer anomaly. Its depth corresponds to the lower crust. 经过三维重力正演计算,我们从台湾的布格重力异常中求得了深部重力异常,其深度相当于地壳下层。
- The magma of porphyritic moyite-monzogranite series in the middle stage mainly originated from the lower crust, being the product of collision-orogeny. 中期似斑状钾长花岗岩-二长花岗岩系列岩浆来源于下地壳,是碰撞造山作用的产物;

- If the squeezing model were correct, he says, one would expect higher temperatures in the lower crust in order for it to be "squeezable. 如果挤压模型是正确的话,他说,那么深部地壳需要有更高的温度使得它更具有可塑性。

- In terms of the multi-layer tectonic model, they are a manifestation ofthe plastic-flow network systems in the lower lithosphere, including the lower crust andthe mantle lid. 根据多层构造模型,这些地震网络系统实际上是岩石圈下层(含下地壳和岩石圈地幔)塑性流动网络的一种显示。
- Sherman recommended that Clarke be disciplined, but higher-ups rejected the idea. 谢尔曼建议对克拉克进行纪律惩戒,但高层拒绝了这个意见。
- The Tongde granulites were probably formed at an active continental margin without geochemistry of WPB.The depletion of Rb-Th and Nb-Ta indicates that the primitive magma of the Tongde granulites was contaminated by the lower crust. Rb-Th和Nb-Ta亏损的共存,指示了同德麻粒岩的原始岩浆曾受到古老下地壳物质的混染。
- In an exciting recent development, however, evidence has been found that suggests that the lower crust underneath Tibet is also flowing southward, directly toward the Himalayan mountain front. 不过最近有项令人兴奋的发展,就是已经找到证据,可以说明西藏地底的下部地壳也是向南流动,直接朝著喜马拉雅山前缘的方向。
- The source area of K-rich magmatic rocks in the Dabie area is closely related to the enriched mantle, while the rocks in the lower Yangtze Valley area are more affined to the lower crust. 大别地区富K岩系的源区与富集地幔密切相关,下扬子地区的则与下地壳有更多亲缘关系。
- At present, mafic rocks from the lower crust in the Dabie Mountains or even in the northern Yangtze plate have been scarce, which may be delaminated and recycled into underlying convecting mantle. 大别山造山带乃至扬子板块北缘现今缺乏厚层镁铁质下地壳,它们也很少出露地表,推测这些俯冲的镁铁质下地壳可能已拆离再循环进入地幔。
- Tom was lying on the lower bunk. 汤姆躺在下铺。
- An in situ zircon Hf isotopic, U-Pb age and trace element study of banded granulite xenoliths from Hannuoba basalt: Tracking the early evolution of the lower crust in the North China Craton. 汉诺坝玄武岩中条带状麻粒岩捕虏体锆石原位Hf同位素、U-Pb 定年和微量元素研究。
