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 is influenced by temperature, the chemistry of air and water, organisms, and numerous other factors.

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

Minerals are formed by atoms arranged in a crystal lattice and can include elements such as sodium and chlorine forming halite. Minerals are categorized based on their chemical compositions, such as oxides, sulfides, carbonates, and silicates.
