Hydrothermal anhydrite in veins is usually hydrated to gypsum by groundwater in around-surface exposures. It is often connected with the minerals halite and sulfur. Gypsum is the most common sulfate mineral.[seventeen] Pure gypsum is white, but other substances found as impurities may well give a wide range of colors to community deposits.
The gypsum business is poised for expansion, driven by increasing demand in construction and agriculture. Innovations in sustainable and eco-friendly gypsum solutions will very likely condition the future market. Rising programs in 3D printing and Sophisticated composites also present new opportunities.

The unusual gypsum sand and The attractive selenite crystals are one of the most ample varieties of the mineral gypsum located here at White Sands National Park.
Gypsum takes place in substantial beds associated with other evaporite minerals (e.g., anhydrite and halite), notably in Permian and Triassic sedimentary formations; it's deposited from ocean brine, accompanied by anhydrite and halite. What's gypsum more, it occurs in appreciable quantity in saline lakes and salt pans and is a vital constituent of cap rock, an anhydrite-gypsum rock forming a masking on salt domes, as in Texas and Louisiana.
