Their analyses thus indicate that siderite decomposed first into magnetite, then into maghemite, ultimately into hematite. In this case, the final oxidation product of siderite was hematite. Thus this sequence is almost opposite to the present observations in which hematite (and not magnetite) grew up first while Mn‐ferrite appeared at about 530°C and persisted as final product (and not hematite).
