A lot of geologic history may hide under the rug of the desert pavement. Theories of Desert Pavement What makes desert pavement dark is rock varnish, a peculiar coating built up over many decades by windblown clay particles and the tough bacteria that live on them. Varnish has been found on fuel cans left in the...

Saltation may not move the larger particles; they may be left and form a desert pavement. Any vegetation, or other item, may also block the wind.

volcanic dust desert regions lying to the west glacial deposits coastal sand dunes; clay minerals form slowly in a desert environment wind blows away clay and soil before it can accumulate to great thickness vegetation is sparse and cannot prevent erosion of soil all of these; How does desert pavement form?

Exposed surfaces of the coarse fragments are commonly coated with a black or brown patina called desert varnish; their buried undersides may be stained orange brown. Little vegetation is present except where soils have developed beneath the pavement.

Because wind moves very light sand particles, leaving behind larger pebbles and cobbles, a "desert pavement" was formed paved by pebbles and cobbles exhumed as wind swept away the fine sand around them.

But desert pavement, formed over thousands of years, impedes the infiltration of water in desert soil, restricting plant development and resulting in desert pavement soils becoming nitrate-rich (and saltier) with time.
