Magnetite: Mineral information, data and localities.

JacobsiteMagnetite Series. MagnesioferriteMagnetite Series. 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 200nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

Volcanogenic massive sulfide ore deposit

Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copperzinc which are associated with and created by volcanicassociated hydrothermal events in submarine environments.. These deposits are also sometimes called volcanichosted massive sulfide (VHMS) deposits. The density generally is 4500 kg/m 3.
