Iron ore: Mineral information, data and localities.

Botryoidal, banded, oolitic and coarsely columnar needle ore also occur. The hematite, in conjunction with other iron oxides replace iron carbonates in the ore. Associated minerals include siderite, magnetite, chamosite and stilpnomelane (U.S.G.S., 1976). A typical outcrop is near Mellen in the SW SW SE Sec. 9 T.44N R.2W (Mudrey, 1979).
