Ettringite
Ettringite is a hydrous calcium aluminum sulfate mineral with the chemical formula Ca6Al2(SO4)3(OH)12·26H2O. It crystallizes in the trigonal crystal system and is classified as a sulfate mineral. The mineral typically exhibits a white streak and a vitreous to pearly luster. It is relatively soft, with a hardness of around 2.5 on the Mohs scale, and has a low to moderate density. Ettringite is commonly colorless or white in appearance. It is an important mineral in the study of sulfate-bearing systems and is often associated with evaporitic or hydrothermal environments. It is grouped under the sulfate mineral class and is recognized for its high water content and unique structural properties.

Etymology
Ettringite is named after Ettringen, a town in Germany, where the mineral was first discovered.
Geological genesis
Ettringite typically forms in low-temperature hydrothermal or evaporitic environments. It is commonly associated with the alteration of sulfide-rich rocks or in the context of cement hydration processes. As a sulfate mineral, it is often found in association with other sulfate and hydroxide minerals.
Occurrence
Ettringite is found in a variety of geological settings, including hydrothermal veins and evaporite deposits. It is also known to occur in cement and concrete as a hydration product. Specific localities are not provided in the given facts.
