The alteration of the original rock to iron ore involved two processes that probably occurred at essentially the same time: (1)oxidation of the iron minerals caused by waters circulating through the rocks (The soluble ferrous iron in the minerals wasconverted toinsoluble hematite, geothite, or limonite). and (2)Continued circulation of water through the rocks gradually dissolved the silica from the iron silicates and the chert and carried it out of the rock.
