Ziesite is a mineral, copper vanadate: formula β-Cu2V2O7. It was discovered in 1980 as monoclinic crystals around fumaroles in the crater of the Izalco Volcano, El Salvador. It is named after Emmanuel G. Zies (1883–1981), an American geochemist who studied Izalco in the 1930s.
Closely related is blossite, also copper vanadate; its formula is given as α-Cu2V2O7. It forms orthorhombic crystals. Blossite was also first described for specimens from the Izalco volcano, it is named after mineralogist Donald F. Bloss (born 1920).
Ziesite and blossite are polymorphs, different crystal structure for the same chemical composition and are quite similar in physical properties.
