A chemically formed sedimentary rock composed of halides and sulfates of potassium, sodium, calcium, and magnesium. Common minerals include sodium halite, sylvinite, camallite, epsomite, mirabilite, gypsum, anhydrite, barite, celestite, etc. The mixture includes dolomite, clay mineral, iron oxide, etc. Generally, there is little debris mixed in the wood body, but there are many intercalations of clay rock in the whole system. Associated with valuable elements such as lithium, rubidium, cesium, bromine, iodine, boron, etc. According to composition, it can be divided into rock salt, gypsum, anhydrite, magnesia salt, etc. Formed in lakes and lagoons in dry climate zones. It is the main raw material for producing potassium salt and sodium salt, and has great value for comprehensive development of lithium, rubidium, cesium, bromine, iodine, boron, magnesium, etc; There are also non-metallic minerals such as gypsum and anhydrite.
