    The Cu and Fe-sulphides are often partiallydissolved or oxidised. The saprolite consists largely of microcrystalline kaolinite and quartz,with minor goethite, high charge corrensite, biotite-vermiculite interstatified mineral andvermiculite. Iron sulphides are replaced by goethite and hematite.

  • GOETHITE (Hydrated Iron Oxide)

    Goethite has had a reputation for making rather uninteresting, dull and "dirty" mineral specimens. This is definitely not true of many of the fine specimens available to collectors today. Some good pieces show splendid radiating clusters of deep black crystals. Massive stalactitic forms show rainbows of irridescent colors on surreal landscapes.

    A nanophase being a precursor to goethite, of guyanaite-type structure termediate between feroxyhyte and goethite. Found together with feroxyhyte, ferrihydrite, and goethite, in Fe-rich freshwater nodules. The structure is based on single chains of edge-sharing FeO 6 octahedra and is thus different from goethite, but resembles HP polymorphs of FeOOH and InOOH.

    Ferrihydrite is a poorly ordered Fe oxyhydroxide mineral commonly found in soils, groundwater aquifers, lake sediments, and hot- and cold-spring deposits. Due to its poorly ordered and nanoparticulate (<10 nm) nature, ferrihydrite is thermodynami-cally unstable with respect to the crystalline Fe-oxyhydroxide phase goethite (Schwertmann 1999).
