siderite alters to either hematite or goethite. Alteration of siderite to hematite probably occurs before the siderite is exposed to surface weathering conditions. The moist weathering environment characteristic of stripmined areas in east Texas favors transformation of the siderite to goethite through dissolution and reprecipitation reactions. Manganese that substitutes for Fe2+ in the siderite structure is also released .
