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 …

We have critically reviewed and discussed currently available information regarding the spin
and valence states of iron in lower mantle minerals and the associated effects of the spin …

A new P wave tomographic model of the mantle was constructed using more than 10 million
travel times. The finite‐frequency effect of seismic rays was taken into account by calculating …

We develop a global‐scale P wave velocity model (LLNL‐G3Dv3) designed to accurately
predict seismic travel times at regional and teleseismic distances simultaneously. The model …

During the last four decades, subduction remained one of the most challenging and
captivating geodynamic processes investigated with numerical techniques. While significant …

This is a survey of mantle provinces (large‐scale seismic anomalies) under North America,
from the surface down to 1500–1800 km depth. The underlying P velocity model was …

Improved constraints on lower-mantle composition are fundamental to understand the
accretion, differentiation, and thermochemical evolution of our planet. Cosmochemical …

Subduction of oceanic lithosphere is the main process by which material from Earth's
surface and atmosphere is recycled back into the deep mantle. Seismic images indicate that …

The geoscience community is increasingly utilizing seismic tomography to interpret mantle
heterogeneity and its links to past tectonic and geodynamic processes. To assess the …

We use a hybrid strategy to obtain anharmonic frequency shifts and lifetimes of phonon
quasiparticles from first principles molecular dynamics simulations in modest size …
