Erosion Landform ( 17. Peneplain )

                                                                                                                                                      Back to Erosion Lanadform

  • A peneplain is a low-relief plain.
  • Representing final stage of fluvial erosion.
  • Extended tectonic stability.

1.The streams reached base level lateral erosion.
2.It is dominant as  higher areas.
3.It between the streams are eroded.
4.Finally, upland is almost gone.
5.The stream floodplains merge in an area of very low.
6.There is no topographic relief.
7.The resulting flat plain is the ultimate stage in the cycle of erosion.

  • Peneplained region show;

  • Area is subsequently uplifted to adjacent orogenic processes.
  • Without internal deformation within the peneplain.

  • The streams will  begin downward erosion.
  • It creating;

                             -Incised meanders
                             -Water gaps
  • A peneplain can mistaken for a depositional plain.
  • The rocks beneath a peneplain have been folded.
  • It tilted by tectonic forces.
  • The rocks beneath a depositional plain lie in horizontal layers.

  • The peneplain concept  developed by William Morris Davis and Walther Penck.
  • Early in the 1900s.
