Ores of this type were formed extensively in Precambrian iron formations by leaching of silica, which commonly constituted in excess of 50 % of the rock. Oxidation changed iron carbonate, silicate minerals, and magnetite to hematite or limonite. The potential iron ore known to exist in an area is called iron ore resource.
