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 …

[HTML][HTML] Atlas of the underworld: Slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity
Across the entire mantle we interpret 94 positive seismic wave-speed anomalies as
subducted lithosphere and associate these slabs with their geological record. We document …

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 …

Earth's evolving geodynamic regime recorded by titanium isotopes
Earth's mantle has a two-layered structure, with the upper and lower mantle domains
separated by a seismic discontinuity at about 660 km (refs.,). The extent of mass transfer …

Seismic structure of the upper mantle beneath eastern Asia from full waveform seismic tomography
To better understand the subsurface behavior of subducting slabs and their relation to the
tectonic evolution of the overriding plate, we conduct a full waveform inversion on a large …

Global adjoint tomography—model GLAD-M25
Building on global adjoint tomography model GLAD-M15, we present transversely isotropic
global model GLAD-M25, which is the result of 10 quasi-Newton tomographic iterations with …

Age of the subducting Pacific slab beneath East Asia and its geodynamic implications
We study the age of the subducting Pacific slab beneath East Asia using a high-resolution
model of P-wave tomography and paleo-age data of ancient seafloor. Our results show that …
