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

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

Park and her colleagues used this observation to infer the viscosity of the mantle. By examining how the Earth deformed over time, they found evidence of a layer about 50-miles thick that is less ...

Despite being composed of solid rocks, the Earth's mantle, which extends to a depth of ~2890 km below the crust, undergoes convective flow by removing heat from the Earth's interior.

Earth’s mantle is divided into three layers: an upper region that extends to about 410 km below Earth’s surface, a mantle transition zone (MTZ) from about 410 km to 660 km depth, and a lower region ...

IN a recent investigation1 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 ...

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

They found a sharp discontinuity, or change in the speed of seismic waves, within the mantle at a depth of 410 miles (660 kilometers), or the bottom of the transition zone between the upper and ...

By examining how the Earth deformed over time, they found evidence of a layer about 50-miles thick that is less viscous (that is, “runnier”) than the rest of the mantle, sitting at the bottom of the ...
