Due to the radiative thermal conductivity of the mineral olivine, only oceanic plates over 60 million years old and ...

A new study suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle.

A new study corrects the recorded depth of an earthquake in Japan, revealing that it was not the deepest in history.

New research reveals that only the oldest and fastest-sinking oceanic plates can transport water deep into Earth’s mantle, ...

Provided you have ever been amazed by the shine of a diamond, then there must have been a moment when you questioned how it entered your jewelry box instead of remaining under the Earth’s surface.

IN a recent investigation 1 I found the travel times of the seismic P waves (longitudinal waves) up to an epicentral distance of about 22° to conform with a structure below the Mohorovičić ...

Unsustainable irrigation and drought have emptied nearly all of the Aral Sea’s water since the 1960s, causing changes extending all the way down to Earth’s upper mantle, the layer beneath the ...

The vertical movement of the mantle is one of the driving forces that brings about large-scale geological changes to the ...

Through in-depth analysis of previous giant-impact simulations and by conducting higher-precision new simulations, the research team found that a significant amount of Theian mantle material ...
