Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Gypsum is a soft, light-colored sedimentary rock deposited in ancient seas that covered Ohio during the Silurian Period. It occurs in both mineral form (selenite) and as a rock in bedded layers. Gypsum occurs interbedded with salt (halite, NaCl) and anhydrite (CaSO 4 ).
