Because gypsum dissolves over time in water, gypsum is rarely found in the form of sand. However, the unique conditions of the White Sands National Park in the US state of New Mexico have created a 710 km 2 (270 sq mi) expanse of white gypsum sand, enough to supply the US construction industry with drywall for 1,000 years.

Rain and snowmelt from the surrounding mountains and upwelling from deep groundwater within the basin periodically fill Lake Lucero with water containing dissolved gypsum. [8] When filled, the lake covers about 10 square miles (26 km 2) at a depth of 2–3 ft (0.61–0.91 m). [3]
An evaporite (/ ɪ ˈ v æ p ə ˌ r aɪ t /) is a water-soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution. [1] 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 ...
The water eventually evaporated, leaving behind huge deposits of alabaster and other minerals. Upheavals of the earth raised the gypsum bed close to the surface. Over time, water streams tunneled caverns through the formation, which contains an abundant quality of selenite crystals, white and pink gypsum as well as deposits of rare black alabaster.
This large, underwater sinkhole formation approximately 300 meters across and 125 meters deep, is famous for its clear blue waters and diverse marine life, making it a popular spot for diving and ...
Shallow water marine sediment primarily features larger grain sizes because smaller grains have washed out to deeper water. Within carbonaceous sedimentary rock, evaporite minerals such as gypsum, anhydrite, and halite may be present. [2] The most common evaporite minerals found within modern and ancient deposits are gypsum, anhydrite, and halite.
In soil science, agriculture and gardening, hardpan or soil pan is a dense layer of soil, usually found below the uppermost topsoil layer. [1] There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water. Some hardpans are formed by deposits in the soil that fuse ...
The main sources of calcium sulfate are naturally occurring gypsum and anhydrite, which occur at many locations worldwide as evaporites. These may be extracted by open-cast quarrying or by deep mining. World production of natural gypsum is around 127 million tonnes per annum. [17]
