Washington, DC-- Even though carbon is one of the most-abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth's interior. Analysis by Carnegie's Marion Le Voyer and Erik Hauri of crystals containing completely enclosed mantle magma with its original carbon content preserved has doubled the world's known finds of mantle carbon. The findings are published in Nature Communications.
