Recycled calcium carbonate is an efficient oxidation agent under deep upper mantle conditions

Ca carbonate transported by subducting slabs could explain elevated ferric iron content in the upper mantle through redox reactions with Fe3+ garnet and graphite as products, according to high-pressure, high-temperature experiments.
