Hematite And Magnetite The Carbonate Siderite

The stable coexistence of siderite mag-netite or siderite magnetite graphite or siderite hematite implies a certain oxygen fugacity was experienced by the rock. Of course reactions 2 through 5 also depend on total pressure and temperature. These variables need to be known to compute a value for CO2 or O2 fugacity
