The gypsum throughout the state was deposited during the Permian, when an arm of the inland sea was cut off from the main body of the ocean. That sea evaporated, leaving behind thick layers of sodium chloride (salt) and calcium sulfate (gypsum and anhydrite). These deposits are called evaporites because they formed from the evaporation of water.
