夏威夷的热点被认为是根深蒂固的地幔热柱产物的教科书例子[威尔逊，1963；摩根，1971]。它与世隔绝的位置远离任何板块边界，应该提供一个机会来检验关于羽流-板块相互作用和相关岩浆作用性质的最基本假设[例如，Ribe和Christensen，1999]。然而，关键地球物理数据的缺乏持续了一场辩论，即夏威夷的火山活动是与羽流有关，还是更浅过程的结果，例如板块因伸展应力而逐渐破裂[Turcotte和Oxburgh，1973]。
The Hawaiian hot spot is regarded as the textbook example of the product of a deep-rooted mantle plume [Wilson, 1963; Morgan, 1971]. Its isolated location, far from any plate boundary, should provide an opportunity to test most basic hypotheses on the nature of plume-plate interaction and related magmatism [e.g., Ribe and Christensen, 1999]. Yet the lack of crucial geophysical data has sustained a debate about whether Hawaii's volcanism is plume-related or is instead the consequence of more shallow processes, such as the progressive fracturing of the plate in response to extensional stresses [Turcotte and Oxburgh, 1973].
