While the first iron ore was likely meteoric iron, and hematite was far easier to smelt, in Africa, where the first evidence of iron metallurgy occurs, limonite is the most prevalent iron ore. Before smelting, as the ore was heated and the water driven off, more and more of the limonite was converted to hematite.

Goethite is also frequent as black crystal sprays that form within geodes on drusy Quartz.
Limonite is a common ore of iron and is always secondary in its origin, formed through the alteration or solution of previously existing iron minerals. Pyrite is often found altered to limonite, the crystal form being at times preserved, giving limonite pseudomorphs.
Limonite is a matrix base of many other minerals, and the term gossan is used as a reference to Limonite when it is used as a a matrix for another mineral or has formed an undesirable staining on top of it. Limonite is extremely common and forms the coloring matter in many soils.

Many of these pyrite veins have now been altered to form limonite or ochre. Ochre also occurs infilling cavities in the Carboniferous Limestone and Dolomitic Conglomerate, or as a replacement orebody, where metalrich groundwaters have chemically replaced the host rock with iron ore.
The names in the above chart are root names and should be preceded by appropriate terms for any significant feature of the rock. The proper order is color, structure, grain size (sandstones only), minor constituents, cement, and root name.
The ore was an oolitic carbonate, occupying the position of the Boyle limestone on the ridge to the east of the creek. Miller regarded it as a replacement of this limestone. The weathered ore in the form of limonite was first mined.
