Desert pavement
Type of desert earth surface / From Wikipedia, the free encyclopedia
A desert pavement, also called reg (in the western Sahara), serir (eastern Sahara), gibber (in Australia), or saï (central Asia)[1] is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans.[2] Desert varnish collects on the exposed surface rocks over time.

Geologists debate the mechanics of pavement formation and their age.
