  • Bauxite - an overview | ScienceDirect Topics

    Bauxites are residually enriched rocks, mostly composed of Al-hydroxides (gibbsite, boehmite and diaspore), kaolinite, Fe-oxy-hydroxides and Ti-oxides, which form from intense lateritic weathering of aluminosilicate protoliths. Lateritic weathering and bauxite formation are generally favored by largely humid, tropical and subtropical climates.
