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 …

Achievements and prospects of global broadband seismographic networks after 30 years of continuous geophysical observations
Global seismographic networks (GSNs) emerged during the late nineteenth and early
twentieth centuries, facilitated by seminal international developments in theory, technology …

Genesis and evolution of kimberlites
Kimberlites are volcanic rocks enriched in CO2 and H2O and derive from the deepest-
sourced melts (up to 300 km) that reach Earth's surface. The mantle processes that generate …

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 …

Assembly of the basal mantle structure beneath Africa
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 …

Vestiges of impact-driven three-phase mixing in the chemistry and structure of Earth's mantle
J Korenaga, S Marchi - Proceedings of the National …, 2023 - National Acad Sciences
Highly siderophile elements (HSEs; namely Ru, Rh, Pd, Re, Os, Ir, Pt, and Au) in Earth's
mantle require the addition of metals after the formation of Earth's core. Early, large …

Long-term core–mantle interaction explains W-He isotope heterogeneities
AL Ferrick, J Korenaga - Proceedings of the National …, 2023 - National Acad Sciences
The isotopic characteristics of ocean island basalts have long been used to infer the nature
of their source and the long-term evolution of the Earth's mantle. Anticorrelation between …

Earth's multi-scale topographic response to global mantle flow
Earth's surface topography is a direct physical expression of our planet's dynamics. Most is
isostatic, controlled by thickness and density variations within the crust and lithosphere, but …

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) …
