A new study uncovers how volatile-rich magmas propel diamond-bearing kimberlites from Earth’s depths. If you’ve ever admired a diamond, chances are it originated from a kimberlite. More than 70% of ...

Diamonds seem to reach Earth's surface in massive volcanic eruptions when supercontinents break up, and they form when continents come together. When you purchase through links on our site, we may ...

Diamonds hitch a ride to the surface through explosive kimberlite eruptions, powered by volatile-rich magmas. New simulations show that carbon dioxide and water are the secret ingredients that make ...

A new study offers clues to the mysteries of kimberlite eruptions, the source of most of the diamonds mined on Earth today. By Maya Wei-Haas While diamonds might look pretty perched atop a ring, the ...

Researchers have discovered a pattern where diamonds spew from deep beneath Earth's surface in huge, explosive volcanic eruptions. When you purchase through links on our site, we may earn an affiliate ...

Boulder, Colo., USA: If you’ve ever held or beheld a diamond, there’s a good chance it came from a kimberlite. Over 70% of the world’s diamonds are mined from these unique volcanic structures. Yet ...

Diamonds hitch a ride to Earth's surface inside a rare magma called kimberlite, but only if that magma stays buoyant.

Geologists are proposing a new model for explaining the eruption of diamond-bearing kimberlites in Northern Alberta. A new study by University of Alberta geologists is proposing a new model for ...

Most diamonds are formed deep inside Earth and brought close to the surface in small yet powerful volcanic eruptions of a kind of rock called “kimberlite”. Our supercomputer modelling, published in ...
