Iron, a commonly known mineral, becomes red or rust colored when oxidized. Olivine Limonite Figure 5. The iron in olivine (Fe 2 Si O 4) is reduced and the iron in limonite (Fe 2 O 3. H 2 O) is oxidized. In addition, the release of silicon and hydration makes the mineral more susceptible to physical weathering.
