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 …

Earth's mantle composition revealed by mantle plumes

D Weis, KS Harpp, LN Harrison, M Boyet… - Nature Reviews Earth & …, 2023 - nature.com
Mantle plumes originate at depths near the core− mantle boundary (~ 2,800 km). As such,
they provide invaluable information about the composition of the deep mantle and insight …

Broad plumes rooted at the base of the Earth's mantle beneath major hotspots

SW French, B Romanowicz - Nature, 2015 - nature.com
Plumes of hot upwelling rock rooted in the deep mantle have been proposed as a possible
origin of hotspot volcanoes, but this idea is the subject of vigorous debate,. On the basis of …

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 …

Petrological evidence for secular cooling in mantle plumes

C Herzberg, E Gazel - Nature, 2009 - nature.com
Geological mapping and geochronological studies have shown much lower eruption rates
for ocean island basalts (OIBs) in comparison with those of lavas from large igneous …

Crustal evolution, intra-cratonic architecture and the metallogeny of an Archaean craton

DR Mole, ML Fiorentini, KF Cassidy, CL Kirkland… - 2015 - lyellcollection.org
The generation of the Earth's continental crust modified the composition of the mantle and
provided a stable, buoyant reservoir capable of capturing mantle material and ultimately …

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) …

A Stracke, M Willig, F Genske… - Geochemistry …, 2022 - Wiley Online Library
The radiogenic isotope heterogeneity of oceanic basalts is often assessed using 2D isotope
