The dunefield is nested within the Tularosa Basin, which is surrounded with the San Andres as well as Sacramento Mountains. These mountains are composed of levels of gypsum. Rainfall and snowmelt from these mountains dissolve the gypsum and clean it right down to basin’s floor. Here it's nowhere to go, very like a bathtub or sink with no drain. The drinking water settles to the basin flooring at its most affordable place, called Lake Lucero. When climatic conditions are optimal, the h2o evaporates, and also the dissolved minerals recrystallize and type selenite crystals. Selenite may be the crystalline form of gypsum. These crystals are really brittle and fragile. Selenite can type large crystals—some as large as bicycle tires! Visitors for the park can see selenite crystals on hikes to Lake Lucero.
Gypsum Just about exclusively takes place in settings where seawater is evaporating or exactly gypsum where groundwater containing dissolved ions from evaporite rocks reforms these ions as gypsum. Being a consequence, gypsum generally happens as layers linked to limestone, dolostone, shale, and rock salt.

Plaster is utilized for generating decorative finishes on partitions and ceilings, although gypsum board is used for inside wall and ceiling construction.
Full Dehydration: If gypsum is heated to better temperatures and for an prolonged time period, it loses all its h2o information, reworking into anhydrous calcium sulfate (CaSO4), typically referred to as “anhydrite.” Anhydrite has unique Qualities compared to gypsum and is particularly much less normally Utilized in development.
