Lavas from hotspots—whether erupting in Hawaii, Samoa or Iceland—likely originate from a worldwide, uniform reservoir in ...

The emerging model of mantle convection suggests that some relatively cool subducting slabs of oceanic plate (blue) are deflected at the 660 km discontinuity (dashed black line) whereas others ...

The chemical uniformity of Earth's mantle is greater than previously believed. Lavas from hotspots—whether erupting in Hawaii ...

Studies on Mars have revealed hidden structures and dense areas beneath old ocean beds, influencing the volcanic activity of ...

Waves in the underlying layer known as the mantle can scour off the keels of continents, buoying their surfaces upward to form prominent landforms far from any active plate boundaries, researchers ...

Flexural isostasy states that this massive region should force the planet's surface downward. But the reverse is true.

Studies of gravity variations at Mars have revealed dense, large-scale structures hidden beneath the sediment layers of a ...

A doughnut-shaped structure almost 3,000 kilometers beneath our feet has been discovered by scientists, providing new clues ...

The Rarotonga (and possibly Samoa) plume materials would have been dispersed into the surrounding asthenosphere by mantle convection. These diffuse plume materials would undergo decompression ...
