Carbon-fluid equilibria and the oxidation state of the upper mantle
IT has been proposed that the oxidation state of the Earth's upper mantle is buffered by C-O fluids in equilibrium with elemental carbon1,2. A large body of data on the oxygen fugacities (fo2) recorded by mantle rocks and their derivative melts now allows us to test this proposal. By comparing...
