- Magnetite | Common Minerals
Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions
- Magnetite: Mineral information, data and localities.
Magnetite is an important iron ore, along with hematite It is usually easily distinguished by being strongly magnetic, with black octahedral crystals Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007)
