Why should one half of our world be losing its internal heat like a runny kettle, and the other retain it like a snug thermos ...

Mantle plumes are columns of hot rock that rise from deep within the Earth’s mantle. These plumes are thought to transmit heat from the core-mantle boundary to the Earth’s surface, especially ...

The D'' layer of the mantle flows in a solid state due to post-perovskite alignment, which accelerates seismic waves by 7%.

Strong new evidence suggests that primordial material from the planet’s center is somehow making its way out. Continent-size ...

If this “Dani plume” truly is a ghost plume, it would be the first one ever detected, and could possibly lead scientists to re-examine just how much heat is moving from the core-mantle ...

As meteorites bombarded one another in Earth’s early history, a reservoir of these precious metals developed when the core formed about 4.5 billion years ago.

According to the collected data, the plume is likely to be around 200–300 kilometers in diameter and as much as 100–300 °C (212–540 °F) hotter than the surrounding mantle.

By simulating the movement of two continent-sized Big Lower-Mantle Basal Structures, or BLOBs, researchers may have uncovered the magmatic engine behind Earth’s most devastating eruptions.

The latest research also strengthens the case made in previous work that some mantle plumes incorporate material from Earth’s core, said the University of Copenhagen’s Waterton.
