查询词典 oceanic trench

The results show that A-type granites in eastern China are of diverse crustal origins. They were either derived from anatexis of old lower crust or resulted from partial melting of recycling juvenile altered oceanic crust, and the latter has net contribution to the continental growth.

结果表明，中国东部A型花岗岩物质来源具有多样性，既可起源于古老下地壳深熔作用，也可由再循环年青蚀变洋壳通过部分熔融产生，后者是大陆生长的重要方式之一。

On the other hand, what we stated in the text book is not wrong. We only want to express that not all the subduction magmatism generate andesite. Many intra-oceanic island arcs are dominated by basaltic rocks. We did not explain why because that would involve many high-level concepts like magma fractionation.

而我们在课本中的叙述也没有错，我们只是想提醒并非所有隐没作用都会产生安山岩岩浆，许多大洋中的岛弧都是以玄武岩浆为主，像是东加与马里亚纳。

Within the closed loop of the andesite line are most of the deep troughs, submerged volcanic mountains, and oceanic volcanic islands that characterize the Pacific basin.

安山岩线是太平洋地貌中最重要的分界线，将中部太平洋盆地较深层的火成镁铁岩及大陆边沿的半沉降火成长英岩分隔开来。

SHRIMP zircon U-Pb ages of gabbro, anorthosite, and plagiogranite from the ophiolitic complex, and related marginal granite in the Jinshajiang area, provides important geochronological constraints for the oceanic spreding, the subduction and final collision, therefore, which constructs a time framework for the Jinshajiang Paleo-Tethys evolution.

应用SHRIMP方法测定了金沙江蛇绿岩中的各类辉长岩，斜长岩，斜长花岗岩，及沿金沙江带分布的陆缘型花岗岩的年龄，提供了洋壳形成，俯冲消减和碰撞造山事件等古特提斯演化的重要的同位素地质年代学制约，从而建立了金沙江古提斯演化的年代格架。

Similar low ozone amounts over the Antarctic continent have been observed by a TOMS instrument on a National Oceanic and Atmospheric Administration satellite, as well as by balloon-borne instruments flown from the South Pole and ground-based spectrometers.

另外，位于美国国家海洋气候管理局的卫星上的'TOMS'仪器，以及从南极放飞的由气球携带的仪器还有陆上的分光计，都已得到相似的数据表明，南极洲臭氧含量过低。

In oceanic terranes, basaltic volcanism is dominant and frequent occurrence.

玄武岩。在海洋地形，玄武火山活动为主体，并经常发生。

This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

这种类型的断层活动是由伸展作用造成的，常常在美国西部的盆岭省以及海底洋岭系统中观测到。

" Numerous Asian, African, Oceanic, and Native American cultures have excelled in basketry."

亚洲、非洲、大洋洲和美洲的原住民等许多文化，在编织工艺上皆有出色的表现。

There is an old wrecked ship, with thick moss all over its sides. You can also find a lot of benthal animals in the cabin, such as shrimps, clown fish and long-arm octopus. The old captain will tell you the stories of oceanic treasure hunting, which are very interesting and attractive.

海底通道里还有一艘古老的沉船，船壁上长满了厚厚的鲜苔；船舱里活跃着虾怪、小丑鱼、长臂章鱼等许多海底精灵；老船长用苍老的声音向您讲述海底探宝的故事，有趣而又充满了诱惑。
