What is geochemistry of gypsum?
Gypsum is a mineral composed of calcium sulfate dihydrate. An evaporite mineral, it forms upon evaporation of surface waters which leaves a more and more saturated solution of the dissolved mineral. For the crystallization process to occur, this usually means that an oversaturated body of water must have less inflow than outflow through evaporation as would be the case with a trapped basin in an arid region.
