Sign in to saveLöweite is a rare evaporite sulfate mineral with the chemical formula Na12Mg7(SO4)13·15H2O. It occurs in marine salt deposits, saline playa crusts, and occasionally as a volcanic sublimation product. The mineral crystallizes in the hexagonal–trigonal system (space group R3) and is typically colorless, though it may appear reddish-yellow due to impurities. Löweite has a vitreous luster and a Mohs hardness of 2.5–3.
