  • Ferricrete

    Ferricrete and laterite are ferruginous duricrusts cemented by iron oxides occurring as indurated continuous crusts and soil horizons in the landscape (Lamplugh, 1902; Bourman, 1993 ). Fundamental to the formation of ferricrete and laterite is the formation and accumulation of insoluble ferric iron in soils and regolith.
