Abstract

High Mn concentrations provide unique indicators of water-rich environments and their redox states. Very high-potential oxidants are required to oxidize Mn to insoluble, high-valence oxides that concentrate Mn in rocks and sediments; these redox potentials are much higher than those needed to oxidize Fe or S.
