Magnetite: Mineral information, data and localities.

Magnetite is an important, strongly magnetic 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 ...

Magnetite

Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron (II) and iron (III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron (II,III) oxide. In the past, it has been called ferrous–ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary rocks.

magnetite mineral in different forms

Magnetite and hematite are two forms of iron ores from which iron can be extracted. Magnetite contains iron in the form of Fe3O4. Hematite contains iron in the form of Fe2O3. The main difference between magnetite and hematite is that magnetite is ferromagnetic whereas hematite is paramagnetic. Are you minerals attracted to magnet?

Magnetite morphology and life on Mars | PNAS

Many studies ( 3, 9 – 14) have shown that magnetite crystals from magnetotactic bacteria exhibit the cube {100}, octahedron {111}, and dodecahedron {110} crystallographic forms. However, T.-K. go considerably further in their interpretations, giving the relative development of the various forms greater significance than do previous authors.

Magnetite is a relatively abundant mineral, for it is a minor constituent of many different types of rocks. Where it is sparser disseminated as large grains in some rocks, the characteristic octahedral crystal form of magnetite is often identifiable. However, the grains are most commonly irregular in shape. Being an oxide, magnetite is highly ...
