Deep-Earth carbon offers clues on origin of life: New organic carbon species linked to formation of diamonds -- and life itself

New findings by a Johns Hopkins University-led team reveal long unknown details about carbon deep beneath Earth's surface and suggest ways this subterranean carbon might have influenced the history of life on the planet.

The team also developed a new, related theory about how diamonds form in Earth's mantle.

For decades scientists have had little understanding of how carbon behaved deep below Earth's surface even as they learned more and more about the element's vital role at the planet's crust. how much carbon and what types exist in fluids at 100 miles below Earth's surface at temperatures up to 2,100 degrees F.
