Gypsum is one of the most widely-used building materials in the world. It is applied in several interior building uses, including in wallboard. Normally, calcium sulphate dihydrate (CaSO 4 •2H 2 O) is used as a raw material and a subhydrate such as hemihydrate (CaSO 4 •0.5H 2 O) or anhydrite (CaSO 4) is produced. The subhydrate is the ...
The first evaporites described in the Spanish geological record occur as pseudomorphs of anhydrite, gypsum and halite in the lower Cambrian of the Cantabrian Range (Álvaro et al., 2000, Marfil et al., 1984). Upper Permian to Triassic evaporites are exposed in the Internal Betic Zone located in the South-East of Spain, but as stated earlier ...

In agriculture, anhydrite is a valuable source of calcium for soil treatment. It is superior to gypsum for two reasons: an equivalent mass of gypsum contains 21% less calcium because of its water content, and anhydrite is far …
It is mined together with anhydrite rock in open pit mining. The output of the mine is crushed and sorted. The intermediate products are composed of about 65% natural gypsum (CaSO4 * 2 H2O) 34% natural anhydrite rock (CaSO4) and 1% soil and gravel that are deposited back in the mine. The material is gained by blasting and digging.

The gypsum-anhydrite rocks in the abandoned quarry at Dingwall (Nova Scotia, Canada) are subjected to physical and chemical weathering, including hydration of the anhydrite, i.e., its transformation into secondary gypsum under the influence of water. This process is known to lead to the localized volume increase of the rock and the formation of spectacular hydration …
Conformably overlying the limestone are the anhydrite and gypsum, here called the Carroll's Corner Formation. Most of the rock is anhydrite, with thin layers and seams of gypsum. At the Macumber end of the cliffs are the mostly overgrown remains of an old gypsum quarry. The anhydrite cliffs reach their prominence at the aptly named White Head.

An independent claim is also included for an application of a mining process to mine a gypsum or anhydrite quarry. The method involves forming tunnels (2) in two gypsum heaps (10, 12), by removing a marl layer (16) which separates the heaps. The tunnels have same width and are spaced at a predetermined distance from each other.
The abandoned gypsum quarry at Dingwall, in Canada, is a unique place with a peculiar "living" landscape created by expansive hydration of anhydrite process actively operating in the weathering zone at the quarry bottom. It causes a rapid volume increase of the rocks and the formation of the unique domed and tepee-like hydration landforms (several meters in length …
