A relatively level surface produced by erosion. Much of Africa is composed of extensive plains, often cutting discordantly across varied geological structures, and these have therefore been identified as erosion surfaces as such (Lister (1965) Rec. Geol. Surv. Malawi 7). See also Ojany (1978) GeoJournal 2, 5. The whole concept is bound up with the theory of the cycle of erosion.
