shallow sea
A chemical sedimentary rock. Evaporites are formed in this depositional environment. Salts, carbonates, and sulfates mostly. Halite, sylvite, calcite, gypsum, etc.
Evaporation and Precipitation
Gypsum and Halite are evaporites because they are formed through the evaporation of water to form crystals.
dont know limestone and gypsum
precipitation from seawater
shallow sea
New Mexico
It is formed by pure gypsum.
Minerals, especially gypsum, is weathered out of the surrounding mountains by rainfall. It is washed onto the floor of the desert where the water evaporates leaving a deposit of white gypsum sand. Wind may then carry this white sand to the surrounding desert and form dunes.

Gypsum is formed underwater, usually between layers of shale and limestone. When the water evaporates and the area dries, the gypsum becomes solid "rock" gypsum.
Gypsum plaster (plaster of Paris) ( CaSO4·½H2O ) A large gypsum deposit at Montmartre in Paris led gypsum plaster to be commonly known as "plaster of Paris"
Anhydrite is formed from dehydrated gypsum or to make it easier to understand when water is added to anhydrite it becomes gypsum as we can see from their chemical formulas [Anhydrite (CaSO4) and Gypsum (CaSO4-2H2O)].
