Over a thousand miles from the surface, in Earth’s D” layer—right on the edge of the liquid metal outer core—there is a weird acceleration of seismic waves. Experiments recreating the phenomenon in a ...

The mantle transition zone, extending between depths of roughly 410 km and 660 km, marks major mineralogical transformations that govern the thermal and chemical evolution of Earth’s interior. Seismic ...

Oceanic lithosphere descends into Earth's mantle as subducting slabs. Boundaries between the subducting slab and the surrounding mantle are defined as slab interfaces, whose seismic imaging is the key ...

Discontinuities are formed when the rocks in the mantle are squeezed together at such high pressures that they abruptly reorganize themselves. They included data from almost 170,000 reflected seismic ...

Scientists have confirmed a rare “impossible” earthquake deep beneath Utah, revealing a hidden source of seismic activity ...

Key alignment: Randomly-oriented crystal samples do not reproduce the shear wave velocity jump at the D" discontinuity, while crystals oriented along the (001) slip plane of the material's lattice do.
