Unknown Ways of How Diamonds Form Come to Light

New findings have revealed long unknown details about how carbon deep beneath the Earth’s surface is helping diamond formation in the Earth’s mantle. The new theoretical model called the "Deep Earth Water" model allowed researchers to determine the chemical makeup of fluids in the Earth’s mantle, expelled from descending tectonic plates. "These mantle fluids with dissolved organic carbon species could ...
