WebJan 16, 2024 · Evaporite minerals form by coming out of a solution where seawater and the waters of large lakes evaporate. Rocks made of evaporite minerals are sedimentary rocks called evaporites. Halides are chemical compounds that involve the halogen (salt-forming) elements fluorine and chlorine. An evaporite is a water-soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution.
