University of Minnesota's Mineral Pages: Calcite

The iron ranges of Minnesota and Wisconsin once held enormous amounts of magnetite and hematite, along with lesser amounts of other iron ores, such as goethite and siderite. Although hematite forms the bulk of the iron ore in Minnesota and Wisconsin iron ranges, enough magnetite occurs in the deposits that many of them were originally discovered and mapped by their impact on compass readings.
