crystal system of magnetite

Magnetite: Mineral information, data and localities.

Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007). May precipitate from supersaturated volcanic gas due to its cooling as

Chapter 2 : Description of Magnetite Structure

Crystal Structure. Magnetite is a member of the Spinel family of minerals, all of whose crystal structures are similar. It exhibits a variety of characteristics, dependant on its temperature. There are three regions of temperature where magnetite behaves differently: (i) between 0K and 119K (the Verwey transition temperature), (ii) 120K to 840K

Mechanism and kinetics of magnetite oxidation under

Maghemite has the same crystal structure as magnetite, consisting of a close-packed oxygen array, but with fewer iron atoms and more vacancies. Ferric ions occupy both tetrahedral and octahedral sites while vacancies are situated only at octahedral sites. When the distribution of vacancies in maghemite is ordered, the lattice becomes tetragonal belonging to the P 4 1 2 1 2 space group type

3.3. Crystal growth and atomic structure of MYR-1 magnetite. The process of crystal growth has been investigated by HRTEM observations on 132 magnetosomes covering grain sizes ranging from approximately 10 to approximately 180 nm in length. We assumed that the observed grain size reflects the growth stage of the crystal, i.e. the smallest and the largest ones should correspond to the
