In geomorphology and geology, a peneplain is a low-relief plain formed by protracted erosion. This is the definition in the broadest of terms, albeit with frequency the usage of peneplain is meant to imply the representation of a near-final (or penultimate) stage of fluvial erosion during times of extended tectonic stability.

Peneplain, gently undulating, almost featureless plain that, in principle, would be produced by fluvial erosion that would, in the course of geologic time, reduce the land almost to baselevel (sea level), leaving so little gradient that essentially no more erosion could occur. The peneplain concept

peneplain. pediplain. African sequence. etchplain. planation surface, any low-relief plain cutting across varied rocks and structures. Among the most common landscapes on Earth, planation surfaces include pediments, pediplains, etchplains, and peneplains. There has been much scientific controversy over the origins of such surfaces.

Peneplain. Most of the peneplains are, however, stabilized by a “desert pavement” consisting of pebbles and coarse sand that protects a thin layer of fine sand (Scholtz, 1972).
