Gypsum (hydrous calcium sulphate) is an evaporite mineral, which is to say that it is formed when a body of water rich in dissolved calcium sulphate either cools, or is concentrated by evaporation, to the point where the calcium sulphate precipates as a solid.
Gypsum is found in extensive, often thick strata where seas or lakes have evaporated. Less commonly it is found as a deposit in volcanic springs, or as veins or a cementing material in other rocks where it has precipitated from calcium-suphlate-rich groundwater in voids, cracks, and the interstices between grains.
