Bog iron ore and limonite mudstones are mined as a source of iron, although commercial mining of them has ceased in the United States. Iron caps or gossans of siliceous iron oxide typically form as the result of intensive oxidation of sulfide ore deposits. These gossans were .
By the operation of meteoric agencies, iron pyrites readily pass into limonite often with retention of external form; and the masses of "gozzan" or "gossan" on the outcrop of certain mineralveins consist of rusty iron ore formed in this way, and associated with cellular quartz.
Limonite. Often brown and earthy, it is formed by alteration of other iron minerals, such as the hydration of hematite or the oxidation and hydration of siderite or pyrite. It probably bears the same relationship to iron oxides that wad and gummite do to manganese and uranium oxides. goethite.
