NONREDOX TRANSFORMATIONS OF MAGNETITE

The transformation of magnetite to hematite, or hematite to magnetite, in nature has generally been considered a redox reaction and linked to a specific redox state of fluid; however, a nonredox reaction, Fe 2 O 3 (hm) + Fe 2+ + H 2 O = Fe 3 O 4 (mt) + 2H +, may have been the principal mechanism for the transformations of iron oxides in nature, especially in hydrothermal environments.
