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, ...

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

Rhythmic pulses of molten rock are rising beneath eastern Africa, according to a new study.The pulsing plume of hot mantle beneath Ethiopia, driven by plate tectonics, is slowly pulling the region ...

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 ...

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

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 ...

All the latest science news on upper mantle from Phys.org. Find the latest news, advancements, and breakthroughs.

The mantle isn’t a complete unknown. Occasionally, volcanic eruptions spew out bits of it – chunks of greenish peridotite, the type of rock that dominates the upper mantle, embedded in basalt ...

Mantle Structure, Mineralogy and Lithological Density Relations The dominantly peridotitic mantle is divided into the UM (Upper Mantle), TZ (transition zone), and LM (Lower Mantle) by seismic ...

They think this layer may extend around the entire globe. This low-viscosity layer could explain some other observations by seismologists that suggested there are “stagnant” slabs of rock that don’t ...
