Sulfate chloride


The sulfate chlorides are double salts containing both the sulfate and chloride anions. They are distinct from the chlorosulfates which have a chlorine atom attached to the sulfur and contain the formula ClSO3−.
Many minerals in this family exist. Many are found associated with volcanoes and fumaroles. As minerals they are included in the Nickel-Strunz classification group 7.DG.
Hey's CIM groups these as 12.2
