Manganite formation in the first stage of the lateritic

Moanda in Gabon where the weathering profile overlies Precambrian, un- metamorphosed calcareous shales. Thus, the genesis of manganite in rocks of diverse origins and mineralogy has been studied under similar regimes of lateritic alteration. This permits an examination of the influence of parent-

Lateritic concentrations of manganese oxyhydroxides and

Latentes result from the weathering of a variety of rocks under humid tropical conditions. When developed at the expenses of Mn2+-bearing parent rocks, laterite consists of a thick mantle made up of manganese oxides and hydroxides. Two main examples are described from tropical Africa. The first example displays a lateritic profile on metamorphic rock; the second example deals with lateritic ...
