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。
Bozhou lies in south of the North temperate Zone, it is mainly affected by tropic oceanic air mass and polar continental air mass, with a climate of seasonal temperate semi-humid monsoon.
亳州市地处北温带南部，属暖温带半湿润季风气候，为热带海洋气团和极地大陆气团交替控制接触地带。
The evidences indicate that the magmas are formed by melting of pyrolite and eclogite (ancient basaltic oceanic crust) in the axial zone of mantle plume.
这说明它们是在地幔柱轴部，由地幔岩和榴辉岩(古玄武质洋壳)组成的源区产生的岩浆形成的。
Lying within the South Temperate Zone, New Zealand has an oceanic climate, without extremes of heat or cold.
