Evaporite

Water-soluble mineral deposit formed by evaporation from an aqueous solution

An evaporite is a water-soluble sedimentary mineral deposit caused by the concentration and crystallization (chemical precipitation) that results when enough of the water solvent evaporates from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes. Evaporites are considered sedimentary rocks and are formed by chemical sediments.
