Diamonds Reveal How Continents Are Stabilized, Key to Earth's Habitability

Diamonds Reveal How Continents Are Stabilized, Key to Earth's Habitability

New research by a group of geoscientists from Carnegie, the Gemological Institute of America, and the University of Alberta demonstrates that diamonds can be used to reveal how a buoyant section of mantle beneath some of the continents became thick enough to provide long-term stability.
