Definition

Stone-covered landscape surfaces consisting of a continuous layer of interlocking particles overlying an essentially stone-free layer of finer materials.

Synonyms

 Desert armor; Gibber (in Australia) and serir (in central Sahara);  Stone pavement

Description

A surface with continuous cover of coarse, angular-to-subrounded rock fragments on stable undissected portions of alluvial fans, terraces, and the valley floors, arranged in such a way as to make a smooth and interlocking surface (Laity 2008; Fig. 1). Desert pavement rock fragments are often coated with desert varnish. Characteristically, gravels are one or two stones thick and sit on a mantle of finer stone-free material (Mabbutt 1977).
