Magnetite in the human body: Biogenic vs. anthropogenic

25/10/2016  Due to its tendency to react with oxygen to form hematite (Fe 2 O 3) and various iron oxyhydroxides (e.g., ferrihydrite, goethite), magnetite can be used as a powerful tool to explore oxygen concentrations in rocks during geological processes, changes in the oxygen content of the atmosphere (e.g., early Earth), and redox conditions in near-surface environments (e.g., oxic-anoxic transition ...

15/05/2017  Various iron oxides have been shown to react with dissolved Fe(II) under oxygen-free conditions to produce GR (e.g., Usman et al., 2012, Guilbaud et al., 2013), while the further transformation of GR into magnetite depends on the ratio of Fe(II)/∑Fe of GR (Guilbaud et al., 2013).

Reduction of Iron Oxides with Hydrogen—A Review ...

Hematite is the oxide with the highest oxygen content, followed by magnetite and wüstite. Wüstite is only stable at temperatures above 570 °C. Below 570 °C, it decomposes to Fe 3 O 4 and Fe. With increasing temperature, the stability area of wüstite expands because not all places in the lattice are occupied by iron ions.
