A crystal of gypsum will feel noticeably warmer than, for instance, a crystal of quartz. Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters.
Calcite
Gypsum has the same chemical composition as the mineral Anhydrite, but contains water in its structure, which Anhydrite lacks. Many Anhydrite specimens absorb water, transforming into the more common Gypsum. Some Gypsum specimens show evidence of this, containing growths of crumpling layers that testify to their expansion from the addition of ...
Natural minerals and industrial by-products rich in Ca and Mg can undergo the carbonation reaction through direct and indirect mineral carbonation processes,, . Recently red gypsum has received an attention to be used as a feedstock for mineral carbonation purposes.
Gypsum outcrop in Clark County 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 hazardous character of gypsum to historic substance, is connected to the conversion reaction calcite- gypsum. The gypsum molecules formed by calcite hold a volume, that exceeds the volume of the original calcite molecule by about . In this context a relevant damage factor is the modification of the water solubility.

Gypsum is a common mineral in Kansas. It is found in thick beds amid layers of sedimentary rocks, such as limestone, shale, and sandstone. Of the three varieties of gypsum—selenite, satin spar, and rock gypsum—Permian-age rock gypsum is mined in Barber County in south-central Kansas and in Marshall County in northeastern Kansas.
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.
