University of Minnesota’s Mineral Pages: Hematite

Goethite (a.k.a. Limonite): Goethite is a hydrous (water-bearing) iron oxide that forms as a direct precipitate in marine water and bogs, and as an alteration of other iron-bearing minerals. Along with hematite, goethite is the other mineral that makes up most of the rust on natural and artificial iron exposures.
