University of Minnesota’s Mineral Pages: Gypsum

Gypsum is a very soft mineral that is easily identified by its hardness, cleavage, and solubility in water. Typically clear to white, gypsum may be colored reddish to brown or yellow if impurities are present. Most gypsum occurs in its massive form, as layers of rock that often intercalate layers of shale, limestone, or dolostone.

Gypsum, selenite: The mineral gypsum information and pictures

Gypsum crystals are known for their flexibility, and slim crystals can be slightly bent. (Though trying to bend good crystals is not recommended, as their flexibility is weak, and if flexed too much they will break.) Gypsum has the same chemical composition as the mineral Anhydrite, but contains water in its structure, which Anhydrite lacks

Gypsum Mineral Uses and Properties

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Generally top slicing is adopted for mining, wherein road leading from entry point of the deposit is prepared and mining is progressed from top to bottom in slices equivalent to the bench height. Face height varies from 10m down to 2m, dependent on gypsum bedding width. The gypsum beds are followed by 0.5 to 2m of dolomite/limestone.

CharacteristicsProductionUsesGypsum 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. It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum. Gypsum is commonly as

Dolomite Uses Britannica

Gypsum is so soft (Mohs hardness of 2) that it can be scratched easily with one’s fingernail. Anhydrite (see photograph) is orthorhombic and resembles granular dolomite in many rocks, but it does not react with dilute hydrochloric acid. When altered, anhydrite usually takes on a thin coating of white gypsum.

Gypsum can also form translucent crystals and may be associated with dolomite, but gypsum only has one very well developed cleavage plane, while dolomite has three that form well-developed rhombs.
