http://www.gemcoach.com/hematite-guide/ WebIRON COUNTY: Goethite is a widespread mineral throughout the Gogebic Iron Range. It forms with hematite as a secondary alteration product of iron minerals in the iron formation and associated ferruginous schists. It often replaces primary minerals such as magnetite, ferrodolomite and siderite. It also forms concretionary and oolitic masses.
