Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known ...

The 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 ...

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 ...

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 seismic discontinuity that occurs at an average depth of 647-654 km, usually called the 660 km seismic discontinuity, is the boundary between the transition zone and the lower mantle. It is ...

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.

A geology researcher is going deep below Earth's surface to understand how some of the most abundant minerals that comprise Earth's crust change under pressure. A Florida State University geology ...

Scientists have mapped deep earthquakes beneath continents, revealing structured seismic patterns that may improve long-term earthquake forecasting.
