DEF

A rock-cut erosion surface formed in a desert by the coalescence of two or more pediments.

OBS

The almost featureless desert surface produced at the end of arid cycle of erosion is called desert peneplain … In fact, a graded surface is formed through the process of pedimentation. This graded surface has been named differently by various geomorphologists as panfan by A.C. Lawson (1915), pediplain by L.C. King, pediplane by A.D. Howard, etc.

OBS

Lawson used the term panfan to designate the termination of the state of geomorphic development in an arid region in the same way the peneplain is found at the end stage of the general process of degradation in a humid region.
