Evaporation and precipitation of gypsum

The evaporation of water is simulated with keyword REACTION. Common precipitates are calcite (CaCO 3 ), gypsum (CaSO 4 .2H 2 O), and Mg-silicate. The chemistry of salt lakes is often rather simple due to the diversion effect and dominated by only a few cations and anions, resulting in {(Ca, Mg)-Cl}, {(Na, Mg)-(Cl, SO 4 )} or {Na-(Cl, SO 4,CO

Geology of a Gypsum Dunefield

Water with dissolved gypsum in it flows to Alkali Flat and Lake Lucero during wet parts of the year, usually during July and August monsoons. There, the heat of the sun causes the water to evaporate, leaving the gypsum behind. Gypsum precipitates out of the water in the form of crystals. Smaller crystals form on the surface of these playas.

Gypsum Wikipedia

Gypsum is moderately water-soluble (~2.0–2.5 g/l at 25 °C) and, in contrast to most other salts, it exhibits retrograde solubility, becoming less soluble at higher temperatures. When gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate, (bassanite, often simply called "plaster") and, if heated further, to anhydrous calcium sulfate (anhydrite).
