Abstract

The thermal stability of siderite (FeCO3) was studied by two independent methods in which the oxygen fugacity of the gas phase was controlled by equilibration with graphite. Both series of experiments indicate that siderite decomposes stably to magnetite + graphite between 455° and 465°C at 500 to 2000 bars PCO2 + PCO.
