Gypsum - Wikipedia

Gypsum is a very common mineral in marine evaporite deposits and may be associated with halite, sylvite, calcite, dolomite, and anhydrite, as well as clay and silicate detrital grains. This requires a volume increase, so original planar anhydrite beds may become crumpled or disrupted as a result of the mineralogical change.
