  • 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.

  • Potash and other Evaporite Deposits Geology for Investors

    Ore MineralsFormationExploration and MiningImportant DepositsCurrently, the most valuable evaporite mineral is Sylvite, also known as Potash, or potassium chloride. It is used as a fertilizer ingredient and is an important plant nutrient.Gypsum (calcium sulfate) is also an important evaporite mineral and is primarily used to make building materials such as drywall. Technically gypsum is the name of hydrated form of the mineral anhydrite, but gypsum is a common name for both.Halite (See more on geologyforinvestors
  • Gypsum Minerals Education Coalition

    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

    Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.

  • Gypsum Windows to the Universe

    You can find gypsum in sedimentary rocks, deserts, and caves. Large amounts can form in layers on a salty sea or lake bottom when water evaporates leaving the mineral behind. Gypsum sometimes forms when water evaporates in sandy areas like deserts. The gypsum crystals can trap sand grains as they grow.
