They host specialized flora and fauna adapted to extreme conditions. Various desert types are defined by precipitation and temperature, with unique geological features like dunes and stone pavements. The text explores human interaction, cultural significance, and threats like desertification.

Evaporites are composed of a variety of minerals, but gypsum, anhydrite, halite, K and Mg salts are the most abundant. Evaporite minerals form in a predictable sequence related to brine chemistry. Thick evaporite deposits occur in basins where continued influx of waters enriched in dissolved materials. Differential loading can cause evaporites to flow and deform.

It details various dune classifications shaped by wind patterns and discusses the impact on human settlements, notably desertification. The page provides a global overview of notable dune locations and includes references to studies on dune management and fixation.

Desert deposits are characterized by thick sets of cross-bedded sandstones and a combination of evaporites, mud, gravel, and fluvial deposits in interdune areas.
