gypsum and halite are formed by what process


  • Gypsum

    Gypsum boards or plasterboards are typical materials used to build light walls. The production process is based on gypsum hydration technology. At the very beginning of the process dehydrated calcium sulfate (gypsum) is converted into CaSO 4 ·0.5H 2 O by heating. Once dehydrated, gypsum is mixed with water, starch, a foaming agent, and other additives.

  • Sediment and Sedimentary Rocks

    Apr 28, 2018· Evaporites - formed by evaporation of sea water or lake water. Produces halite (salt) and gypsum deposits by chemical precipitation as concentration of solids increases due to water loss by evaporation. This can occur in lakes that have no outlets (like the Great Salt Lake) or


  • Gypsum

    Evaporite (/ ɪ ˈ v æ p ə r aɪ t /) is the term for a water-soluble mineral sediment that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes.

    Jun 01, 2016· Halite crystallizes in the cubic system, with a face centered lattice, f.c.c. (space group Fm3m), its lattice parameter being a 0 = 5.64Å. Halite, along with all the f.c.c. alkali halides, exhibits a peculiar feature: while the ideal surface structure of both the cube {100} and the rhomb-dodecahedron {110} are not polar since the lattice planes of indices h00 and hh0 are electrically neutral ...


  • Evaporites

    Rocks formed by the evaporation of water are called evaporites - gypsum, anhydrite, halite (common salt). This evaporation may occur in either shallow basins on land or in the sea. Material (salts) is eroded from land surfaces and is then carried to the sea by rivers. When seawater evaporates, the salts precipitate and settle to the bottom.

    Since halite is a very light mineral, it often "punches up" through heavier sedimentary rocks to create salt domes near the surface of the earth. These domes are important mining sources for rock salt. They are also indicators of natural gas and crude oil, for these naturally occurring compounds sometimes get trapped underneath the salt domes.

    Gypsum is readily identified by its softness (a fingernail scratches it). Gypsum comes as clear crystals that display one perfect cleavage (selenite), as blocks of featureless white rock (alabaster), and as silky fibrous blocks (satin spar). Halite (next page) breaks into cubes (three cleavages at right angles) and tastes like table salt.
