lateritic in Science
A red, porous, claylike soil formed by the leaching of silica-rich components and enrichment of aluminum and iron hydroxides. They are especially common in humid climates. Laterites that are poor in iron oxides and rich in aluminum oxides are called bauxites. Also called latosol. See more at bauxite.
