Mantle plumes and their role in Earth processes

AAP Koppers, TW Becker, MG Jackson… - Nature Reviews Earth & …, 2021 - nature.com
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 …

A tree of Indo-African mantle plumes imaged by seismic tomography

M Tsekhmistrenko, K Sigloch, K Hosseini… - Nature Geoscience, 2021 - nature.com
Mantle plumes were conceived as thin, vertical conduits in which buoyant, hot rock from the
lowermost mantle rises to Earth's surface, manifesting as hotspot-type volcanism far from …

Assembly of the basal mantle structure beneath Africa

N Flament, ÖF Bodur, SE Williams, AS Merdith - Nature, 2022 - nature.com
Plate tectonics shapes Earth's surface, and is linked to motions within its deep interior,. Cold
oceanic lithosphere sinks into the mantle, and hot mantle plumes rise from the deep Earth …

Large low shear velocity provinces (LLSVPs), whose origin and dynamic implication remain
enigmatic, dominate the lowermost mantle. For decades, seismologists have created …

A tectonic-rules-based mantle reference frame since 1 billion years ago–implications for supercontinent cycles and plate–mantle system evolution

RD Müller, N Flament, J Cannon, MG Tetley… - Solid Earth, 2022 - se.copernicus.org
Understanding the long-term evolution of Earth's plate–mantle system is reliant on absolute
plate motion models in a mantle reference frame, but such models are both difficult to …

Deflating the LLSVPs: bundles of mantle thermochemical plumes rather than thick stagnant “piles”

A Davaille, B Romanowicz - Tectonics, 2020 - Wiley Online Library
Based on SEMUCB‐WM1 tomographic model, validated by other recent models, and fluid
mechanics constraints, we show that the large low shear velocity provinces (LLSVPs) …

The tungsten-182 record of kimberlites above the African superplume: Exploring links to the core-mantle boundary

S Tappe, G Budde, A Stracke, A Wilson… - Earth and Planetary …, 2020 - Elsevier
Many volcanic hotspots are connected via 'plume'conduits to thermochemical structures with
