Geochemical evidence for high volatile fluxes from the mantle at the end of the Archaean

The outpouring of volatiles from the interior of the Earth is held in balance by the return of volatiles at subduction zones, where pieces of ancient oceanic crust, laden with seawater, are returned to the mantle.

Superdeep diamonds confirm ancient reservoir deep under Earth’s surface

Analyses show that gases found in microscopic inclusions in diamonds come from a stable subterranean reservoir at least as old as the Moon, hidden more than 410 km below sea level in the Earth's mantle.

Where do blue (boron-bearing) diamonds come from?

Type IIa diamonds were originally loosely treated as constituting a single unique population, but recent research has shown that they represent multiple populations, formed in association with a variety of different mantle rocks.

How Earth’s mantle is like a Jackson Pollock painting

A new paper paints an even more intricate picture of the mantle as a geochemically diverse mosaic, far different than the relatively uniform lavas that eventually reach the surface.
