Occurrence. Gypsum is deposited from the lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Hydrothermal anhydrite in veins is commonly hydrated to gypsum by groundwater in near-surface exposures.
feel that gypsum deposits are a result of seas which once covered the area where the deposits are located. Evidence of this can be seen today in the Caspian Sea and on the West Coast of the Baja in California. Gypsum usually occurs in veins or ledges, but word gypsum.

Gypsum forms the basis for some of the well-known brands of toothpaste, and, thereby helps to pay the salary of some of televisions best-known en-tertainers. Most of the fixtures in bathrooms are made of clay formed in a mold of gypsum plaster and chances are that gypsum board is behind the wall tile. Gypsum Molds . . .
The type of sediment within which gypsum grows has only minor effects on its morphology unless the sediment is contaminated with soluble organics. These observations help to explain why lenticular gypsum forms in some instances, and prismatic gypsum in others, within natural sedimentary environments.
Jun 21, 2007 Colonized gypsum is commonly present in this region. Gypsum increases dramatically with depth, ranging from 14% in the surface to 90% within 20 cm, forming shallow petrogypsic horizons. Visual inspection reveals that the pattern of colonized gypsum is similar to one another, thus only one representative sample was analyzed.

Gypsum that occurs in nature is called mineral gypsum. In addition to mineral gypsum, seawater and some chemical and fertilizer plants are sources of by-product marine gypsum and by-product chemical gypsum, respectively. The latter is obtained as by-product phospho-gypsum or fluoro-gypsum or boro-gypsum, depending upon the source.
