Infrastructure and Construction Materials Guide — Gypsum

Commercial deposits of gypsum may be almost pure, or contain variable amounts of impurities such as limestone, dolomite, clay, anhydrite, and soluble salts of potassium, sodium, and magnesium. Primary gypsum deposits consist of rock gypsum (alabaster). Selenite, satin spar, and gypsite are secondary varieties of gypsum.
