1·If that happens, slab pull could draw the oceanic crust under the continent, actually causing the Americas to move eastward toward Europe and the ocean floor to get smaller.
若果真如此,岩板拉力会将海洋地壳拖拽到大陆之下,实际上会使美洲大陆向东移动靠近欧洲,海床也会缩小。
2·Inthis article, the relationship of ODP with the research of oceanic crust is discussed.
本文论及了ODP与大洋地壳研究的关系。
3·Yellow Sea area, located between the margin of China's mainland and the oceanic crust of...
中国大陆边缘和西太平洋洋壳之间的黄海海域,属于过渡型地壳结构。
4·The earth′s crust of the South China Sea belongs to the transitional type between the oceanic crust and continental crust.
南海地壳属于大洋型地壳与大陆型地壳之间的过度类型。
5·The oceanic crust thus serves as a magnetic tape recording of the history of the geomagnetic field that can be dated independently;
这样海洋壳就扮演了磁带的角色,记录下可以鉴定时 间的地磁场的历史。
6·Owing to the difficulty of sampling beneath the deep oceans, the composition of the oceanic crust is not known with complete certainty.
由于在深海底下取样困难,海洋地壳的组成就不完全确知。
7·Tectonic environment of formation of enriched upper mantle is oceanic crust displacement from the oceanic mid-ridge to the orogenic zone.
造山带富集型上地幔形成的构造环境是:洋壳从扩张脊向两侧运移并最终拼入造山带这段时间内。
8·But geophysicists had thought that great subduction-zone earthquakes happened only where younger oceanic crust scrapes its way into the mantle.
但是在此之前,地球物理学者们认为,这种俯冲带大地震仅仅在年轻的海洋地壳挤入地幔处才可能发生。
9·The existence of recycled basaltic oceanic crust in the axial zone of mantle plume may be the key of the formation of giant V-Ti-magnetite deposits.
岩浆源区再循环玄武质洋壳的存在可能是该区超大型钒钛磁铁矿床形成的根本原因。
10·It is considered that the crust in the Okinawa Trough area belongs to the transition type, which is quite similar to the feature of the oceanic crust.
综合分析认为:冲绳海槽地壳属于过度型地壳,与大洋地壳的许多特点颇为相似。
