South African diamonds have revealed nickel-rich metallic inclusions, offering the first direct evidence of reactions predicted to occur deep in Earth’s mantle. The study shows how oxidized melts ...

A pair of diamonds that formed hundreds of kilometers deep in Earth’s malleable mantle both contain specks of materials that ...

These diamonds acted as “tiny time capsules,” preserving a rare snapshot of deep Earth processes. “This is a rare snapshot of mantle chemistry in action,” said Yaakov Weiss, the study’s lead author.

Their findings could shed more light on the layers that make up the Earth and how they are interconnected, coauthor and ...

A recent study reveals dynamic transformations in Earth's lower mantle, impacting both earthquakes and the magnetic field. GRACE satellites detected a ...

Earth's mantle is a restless, enigmatic engine that powers volcanism, recycles crust, and regulates the long-term evolution ...

Diamonds hitch a ride to the surface through explosive kimberlite eruptions, powered by volatile-rich magmas. New simulations ...

Diamonds from South Africa's Voorspoed mine have revealed the first natural evidence of nickel-rich metallic alloys forming deep in Earth's mantle ...

A recent study published in Communications Earth & Environment has unveiled an extraordinary discovery: the solid rock deep beneath our feet is not as rigid as previously thought. Scientists have ...

Scientists found that carbon enabled Earth’s core to solidify. Without it, the inner core may not exist. A team of scientists from the, University of Leeds, and University College London has uncovered ...

It is now thought that the source of this anomaly was a phase transition in which one mineral’s structure was altered.

A team of Japanese researchers hopes to drill through the Earth's crust and reach the mantle directly. This would be a major achievement; our efforts to reach the mantle to-date have not been ...
