"A new classification and terminology of rocks in the series bauxite-clay-iron oxide ore based on their quantitative mineral composition is proposed. . . . The terms laterite and bauxite are explained not only from their substantive, but also from their genetic, point of view. Laterite is a relatively untransported weathered product, containing free aluminum hydroxide, derived in situ from the parent rock, whereas bauxite is a transported weathered product (detrital mode of occurrence). Both of these rocks, however, have the same mineral composition."
