Abstract

Hydrothermal alteration experiments in sulfuric acid solution with graphite and CO2 atmosphere were carried out. Sulfuric acid oxidizes Fe2 + in silicate minerals and make Fe-Oxide. Presence of graphite, however, can inhibit the formation of Fe-Oxide with sulfuric acid under CO2 atmosphere.
