IRON COUNTY: Magnetite is abundant in the iron formation in the Gogebic Range from Upson to Hurley where it is found as small crystals and masses intergrown with siderite, ferrodolomite, chlorite, calcite and quartz. It is also a component of the actinolite schists with the iron formation, where is forms small crystals, masses and clusters ...

This means that chemical weathering transforms the crystals of pyrite into limonite by hydrating the molecules, but the external shape of the pyrite crystal remains. Limonite pseudomorphs have also been formed from other iron oxides, hematite and magnetite; from the carbonate siderite and from iron rich silicates such as almandine garnets.
