The Bent Hawaiian-Emperor Hotspot Track: Inheriting the Mantle Wind

Tarduno, John;, Hans-Peter; Bunge, Norm; Sleep, and Ulrich Hansen (2009), The Bent Hawaiian-Emperor Hotspot Track: Inheriting the Mantle Wind, SCIENCE, 324(5923), 50-53, doi:10.1126/science.1161256.

Abstract
Bends in volcanic hotspot lineaments, best represented by the large elbow in the
Hawaiian-Emperor chain, were thought to directly record changes in plate motion.
Several lines of geophysical inquiry now suggest that a change in the locus of
upwelling in the mantle induced by mantle dynamics causes bends in hotspot tracks.
Inverse modeling suggests that although deep flow near the core-mantle boundary may
have played a role in the Hawaiian-Emperor bend, capture of a plume by a ridge,
followed by changes in sub-Pacific mantle flow, can better explain the observations.
Thus, hotspot tracks can reveal patterns of past mantle circulation.
