  • Evaporite Wikipedia

    Evaporite (/ ɪ ˈ v æ p ə r aɪ t /) is the term for a water-soluble mineral sediment that results from concentration and crystallization by evaporation 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.Онлайн-запрос
