Gypsum – Virtual Museum of Molecules and Minerals

Gypsum is by far the dominant sulfate mineral in soils. A saturated gypsum solution at 25C contains ~15 mM CaSO 4, or 2.63 g/L. It is approximately 100 times less soluble than other common sulfate minerals. Gypsum is not common in soils of more humid regions due to its relatively high solubility in water and its rapid removal in leachate.

Crystal Structure and Physical Properties of Gypsum Mineral

Cleavage planes in gypsum crystals are a defining feature of the mineral's structure. Gypsum exhibits perfect cleavage along its planes, allowing it to easily split into thin sheets or plates. This unique characteristic is a result of the crystal's internal atomic arrangement, which enables it to break cleanly and smoothly along these planes.
