TEM investigations on goethite and hematite associated with kaolinite in lateritic weathering profiles (Cameroon) have shown : (1) the variability of goethite habit, in contrast to hematite, according to sampling locality, (2) the occurrence of intermediate phases, primary or resulting from a topotactic transformation of hematite into goethite, (3) intergrowths of hematite and goethite, and (4) epitaxy of goethite upon kaolinite. These data are discussed in terms of growth and genetic relationships between minerals (mineral development and relative stability). Petrological implications are considered.Une étude en microscopie et diffraction électroniques a été réalisée sur des échantillons de goethite et d'hématite, associées aux kaolinites...
