In Earth’s Magma Ocean, Carbon Chemistry Got Complicated

Computer simulations of the magma ocean on early Earth suggest that the carbon chemistry was surprisingly complex at high pressure. Iron likely sequestered much of the carbon into the metallic core while diamonds may have formed from clusters of carbon.
