Gypsum is a type of soft sulfate mineral known for its usefulness in day-to-day lives. It is also referred to as calcium sulfate dihydrate. It consists of water, calcium sulfate and oxygen molecules and is chemically represented by the formula CaSO 4.2H 2 O. An evaporite mineral, gypsum is mostly found in layers of sedimentary rocks on the earth's crust along with other minerals such as ...

G. Cressey, in Encyclopedia of Geology, 2005 Introduction. Gypsum (CaSO 4 · 2H 2 O), the most common of the sulphate minerals, is also known as alabaster (a fine-grained massive form), satin spar (a fibrous variety of gypsum), or selenite (colourless transparent gypsum crystals). Gypsum is often found in considerable thicknesses within evaporite sequences and in association with limestones ...
