Description:
In this study, we have examined the thermal decomposition of two volatile-bearing iron minerals, in particular, lepidocrocite (gamma-FeOOH) and siderite (FeCO3), under Mars-like pressures. Both minerals exhibit different enthalpic events during their decomposition at reduced atmospheric pressures when compared to those at ambient pressure. These differences in energetics are related to the mechanisms of thermal decomposition at Mars-like pressures. Such knowledge regarding the thermal stability of volatile-bearing minerals on Mars will provide useful information for planetary surface processes.
