A phase change in post-perovskite materials at the so-called D” discontinuity is also evidence for long-predicted slow, convective flows in the mantle itself ...

Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...

They reveal that the chemical composition of the deep mantle has remained almost intact since the Earth's formation 4.5 ...

Scientists discover hidden "ghost plume" beneath Oman using earthquake data, revealing Earth's secret heat pathways.

Evidence has been found for a mantle plume beneath Oman, on the Arabian Peninsula. Unlike all the confirmed mantle plumes found before, however, this one is not associated with current or recent ...

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than ...

The mantle, hidden far below your feet, moves and changes over time in ways we’re only starting to understand. With new tools like full-waveform inversion, scientists can now see parts of Earth ...

Like most of us, Earth has a lot going on under the surface — even in what may have once seemed to be its most unassuming layer. The mantle, a zone between our planet’s thin crust and the ...

Lower Mantle The region of the Earth that lies beneath the upper mantle and surrounds the outer core, is known as the lower mantle. located 400 to 1,800 miles below the Earth's surface, the layer ...

The study was published in Nature Geoscience. The lower mantle is an important layer of the Earth and may play an important role in the evolution and material cycling of Earth's interior.

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 ...
