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

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 ...

A new study, using convection models, shows that Earth’s collision with the protoplanet Theia some 4.5 billion years ago, might’ve triggered early subduction in Earth’s crust.

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 ...

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

Mars has northern and southern hemispheres like Earth, but their defining characteristics are markedly different, a phenomenon known as Martian dichotomy. The Southern Highlands are older, higher ...

That’s when convection takes over, as heat from the Earth’s core causes a very slow creeping motion of materials in the solid mantle and the ensuing currents carry heat from the interior to ...

The depths of the Earth still hold many surprises. A team of scientists has discovered that objects move horizontally in the Earth's mantle, nearly 1,864 miles (3,000 km) beneath our feet.

In this illustration, parts of the ancient planet Theia sink and accumulate at the bottom of the Earth’s mantle. This forms two ‘blobs’ called large low-velocity provinces (LLVPs) deep ...

The lower mantle of Gaia, denoted by the dashed circle with a radius of 0.8 Earth radii (RE), is only marginally contaminated by Theian mantle. Credit: Bi Rongxi and Deng Hongping ...
