"Formed by the evaporation of saline deposits from seawater, gypsum is an abundant mineral found in all parts of the world. Some of the most notable national deposits include California, Utah, Colorado, New Mexico, Ohio and Michigan. Gypsum is also commonly found in France, Switzerland and Mexico, and other parts of the world.

Due to its unique properties, and because it is non-toxic, Gypsum is used in a seemingly endless number of products including: food additives, beer brewing, casting plasters, toothpaste, medicines, and as a soil amendment in the agricultural industry."

hope this helps...
