  9. Saprolite - Wikipedia

    en.wikipedia.org/wiki/Saprolite

    Ferromagnesian minerals are the principal hosts for nickel, cobalt, copper and zinc in sulfide-poor mafic and ultramafic rocks, and are retained higher in the profile than sulfide-hosted metals. [1] They are leached from the upper horizons and reprecipitate with secondary iron-manganese oxides in the mid- to lower saprolite.
