One important finding was that most of the geomagnetic field originates at only four broad regions on the core-mantle boundary. 重要的发现之一，是地球的大部份磁场仅来自地核–函交界面上的四个广大区域。 - 2
The mantle upwelling is originated from core-mantle boundary and mostly presents in the middle mantle and lower part of upper mantle. 地幔上升流起源于核幔边界，主要表现在地幔中部和上地幔下部。 - 3
The plumes apparently originate at great depths, perhaps as deep as the boundary between the core and the mantle, and many have been active for a very long time. 这些地幔柱显然起源于很深的地方，可能深至地核和地幔之间的边界，而且许多都已经活跃了很长时间。
