The Arizona mine is the type locality. Papagoite is one of only a few four membered ring silicates. These silicates have four silicate tetrahedrons linked into a ring forming a distorted square-like structural element. Papagoite is named for the Papago Indian tribe of Arizona. It forms as a secondary mineral on slip surfaces and in veins in altered granodiorites.
Color is a dark sky blue in crystals and a paler blue in massive veins.
Luster is vitreous to dull. Crystal Habits include tiny flattened, elongated crystals sometimes formed into spherical aggregates and massive vein filling material. Cleavage is imperfect in one direction. Streak is pale blue. Associated Minerals are limited to aurichalcite , ajoite , barite , shattuckite and limonite .
