Know MoreEvaporites
Evaporit 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 ....

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 ....

Jul 15, 2011· Perhaps the most interesting implication of the close association of gypsum, anhydrite, and halite relics in the McArthur Group is that the temperature during the deposition of these minerals was not much above 18 °C, the temperature at which gypsum, anhydrite, and halite are stable together (Hardie, 1967) At higher temperatures, anhydrite is ....
