Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is commonly found in sedimentary rock formations and is often associated with other minerals such as anhydrite, halite, and sulfur. The name “gypsum” is derived from the Greek word “gypsos,” which means “plaster” or “chalk.”1. Use Figure 2.16 to identify the environment (s) (A-L) where the sediment for the following sedimentary rocks could have been deposited.

ISBN: 9780134746241.GYPSUM — Gypsum is widely distributed in Texas. Chief deposits are bedded gypsum in the area east of the High Plains, in the Trans-Pecos country, and in Central Texas. It also occurs in salt-dome caprocks of the Gulf Coast. The massive, granular variety, which is known as rock gypsum, is the kind most commonly used by industry.Gypsum stones usually show no attractive colors, though impurities may add pale shades. This material has a surprisingly high dispersion of 0.033 but just can't receive a cut to show it off. Of course, a faceted piece would make a rare addition to a mineral or gem collection and a wonderful showcase of the art of faceting.Gypsum can be found in crystalline form or in massive beds called gypsum rock, and it forms in lagoons as ocean waters high in calcium and sulfate evaporate and are replenished. Gypsum is mined and extracted from quarries and underground mines. The gypsum ore is crushed, screened, and dried if needed.Gypsum. Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers.Rock gypsum is an example of an evaporite rock.
