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 ...

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

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.

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

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

An international research collaboration has harnessed supercomputing power to better understand how massive slabs of ancient ocean floors are shaped as they sink hundreds of kilometres below the Earth ...

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

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