    Oct 18, 2015· Gypsum is a relatively rare constituent of sand. An exception is a large dune field in New Mexico White Sands National Monument that is entirely composed of tabular gypsum grains. Why is gypsum rare in sand? Because it is moderately soluble in water. Gypsum crystallizes out of concentrated solutions — it is an evaporite mineral.
