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.

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, common sulfate mineral of superb industrial significance, composed of hydrated calcium sulfate (CaSO4 ·2H2O). In properly-developed crystals the mineral normally has been called selenite. The fibrous large variety has a silky lustre and is known as satin spar; it is translucent and opalescent and is valued for ornaments and jewellery.
