  • Gypsum - Wikipedia

    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.A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including ...

  • How Is Gypsum Formed? Hunker

    OverviewChemistryGeologyFormationGypsum is a sedimentary rock and a crystalline mineral. Gypsum is a soft, white to gray, \"chalky\" mineral composed of calcium sulfate and water, says Raymond Anderson of Iowas Department of Natural Resources. Gypsums chemical symbol is CaSO42H2O. Found in many parts of the world, it can occur as crystals or as deposits in beds.在hunker上查看更多信息

    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

    Why is gypsum rare in sand? Because it is moderately soluble in water. Gypsum crystallizes out of concentrated solutions — it is an evaporite mineral. It can also quite easily go into solution again. Anything soluble is generally not going to last long in sand. Gypsum sands in New Mexico exist there because this state is not too famous for a wet climate, quite the contrary. The area also has ...
