Jacobsite-Magnetite Series. Magnesioferrite-Magnetite 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 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

FE SKARN DEPOSITS (MODEL 18d; Cox, 1986) - USGS

2004-4-5  Magnetite is the principal ore mineral in iron skarns. Ore grades are typically 40 to 50 weight percent iron but these deposits have relatively low sulfide mineral contents and therefore relatively low acid-generating potential. In addition to the acid-buffering potential afforded by the common presence of carbonate-bearing strata, epidote
