As a rock, gypsum is a 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 a mineral commonly found in Kansas. When salty seawater evaporates, dissolved salts, including the mineral gypsum, are left behind. If conditions are right, large quantities of gypsum build up into thick beds of sedimentary rock. The gypsum throughout the state was deposited during the Permian, when an arm of the inland sea was cut ... It takes the form of crystals which can at times be found projecting from rock – leading to its old English name of the Spear Stone. The largest gypsum quarries in Europe are found in France, Germany, Italy, Poland, Spain, and the UK. There is also evidence of gypsum dunes on Mars. Gypsum is composed of calcium sulphate (CaSO4) and water (H2O). Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. This chapter reviews all that is known about speleothems (calcite and gypsum), with particular reference to those forms that are found exclusi- vely in the ...

Gypsum speleothems form because water seeping into the cave often contains small amounts of gypsum (calcium sulfate, CaSO4) picked up from the limestone or overlying sandstone. When this water evaporates in the cave, it deposits gypsum in the form of needles, beards, flowers, or spiders. Gypsum formations are found only in dry parts of the cave.

When water is added to either hemihydrate or anhydrite, these phases rehydrate to form gypsum in an exothermic reaction. Two phases of hemihydrate result when gypsum is dry or wet heated: α-hemihydrate and β-hemihydrate, each with distinct physical properties (Kelley et al., 1941). The α-hemihydrate is produced by wet heating (in a humid ...Feb 24, 2023 · How Does Gypsum Form? Gypsum is a naturally occurring mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is formed when water-bearing rocks, such as limestone, are exposed to sulfuric acid. Gypsum is one of the most common minerals in sedimentary rocks and is found in abundance in many locations around the world. May 24, 2018 · Gypsum sand is relatively rare because it is water soluble and easily dissolved. Because the Tularosa Basin is fully enclosed, little gypsum is lost over time: The limited moisture that falls as rain or snow is trapped in the basin, where it evaporates and leaves behind any dissolved gypsum in the form of selenite crystals, some over a meter long. Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 O). It is a natural mineral that occurs in certain types of sedimentary rocks. Gypsum forms when water evaporates in mineral-rich marine soil environments. Over long periods of time, evaporation brings more minerals to the soil surface, eventually forming a solid deposit. Gypsum is considered an evaporate and forms when evaporation of water allows oxygen to bond with the surrounding sulfur to create sulfate. The sulfate will then bond with surrounding calcium and water to create the final product gypsum. Gypsum has the following properties: Mohs Scale Hardness : 1.5 – 2. Specific Gravity: 2.31 – 2.33.Gypsum has many interesting properties, including its very unique crystal habits.
