Deeply weathered saprolite beneath duricrusts is diagnostic of the African surface. Detailed cartographic analysis, supported by field investigation, has been applied to the African surface residuals located between Albertinia and Mossel Bay in the southern Cape, South Africa. Four distinct surfaces at differing elevations exist. These results support the view that the African surface, as it survives, is polycyclic.
