Jarosite-geoethite stabilities at 25 °C, 1 ATM | SpringerLink

Abstract. Eh, pH and log activity diagrams were calculated to demonstrate the equilibrium relationships between jarosite-goethite-pyrite at 25 °C, 1 atm. Interpretation of these diagrams in light of natural occurrences of iron minerals in the oxidation zone of a sulfide deposit indicates that goethite (or hematite) is the stable mineral in the normal weathering environment.
