Mantle plumes and their role in Earth processes
The existence of mantle plumes was first proposed in the 1970s to explain intra-plate,
hotspot volcanism, yet owing to difficulties in resolving mantle upwellings with geophysical …

A review of large low shear velocity provinces and ultra low velocity zones
AK McNamara - Tectonophysics, 2019 - Elsevier
Seismic tomography reveals 2 extensive regions in the lowermost mantle, beneath Africa
and the Pacific, that exhibit lower-than-average seismic wave speeds. These regions have …

Shear and compressional velocity models of the mantle from cluster analysis of long-period waveforms
We present a new technique for the efficient measurement of the traveltimes of long period
body wave phases. The technique is based on the fact that all arrivals of a particular seismic …

Supercontinent–superplume coupling, true polar wander and plume mobility: plate dominance in whole-mantle tectonics
Seismic tomography has illustrated convincingly the whole-mantle nature of mantle
convection, and the lower mantle origin of the African and Pacific superplumes. However …
