Abstract

The oxidation-reduction ('redox') state is an important intensive property of any geologic system and is typically measured (and reported) as either the redox potential (E-h) or the oxygen fugacity (f(o2)). These two concepts cover the whole spectrum of geologic systems: from low-temperature aqueous and sedimentary systems to high-temperature rock-forming environments. The redox state determines the speciation of a fluid phase and exercises fundamental controls on phase relations and geochemical evolution. Here, we review the concepts that underpin the redox state and outline a framework for describing and quantifying the concept of the oxidation state.
