The chemical formula of mineral Papagoite is indicated by CaCuAlSi2O6(OH)3 or Calcium Copper Aluminum Silicate Hydroxide. Papagoite is actually a Silicate mineral. It is most commonly used as mineral specimen and it is most commonly found exhibiting nice and interesting microscope images when viewed under polarizing microscopes used in optical mineralogy. Mineral Papagoite is actually another rare silicate mineral from a known mine in Arizona, USA. Papagoite is usually found at only one mine, the New Cornelia Mine at Ajo District in Pima County, Arizona, USA. Another known location is at Messina, Transvaal. South Africa. However, Arizona is its type of locality. Papagoite is only one of the few four ringed silicate minerals known in optical mineralogy. In optical mineralogy, these silicate minerals have four silicate tetrahedrons linked into a ring forming a distorted square-like structural element. Mineral Papagoite is actually named for the Papago Indian tribe of Arizona.

 

            Mineral Papagoite is most commonly found dark sky blue in color if in crystal form and paler blue in massive veins when viewed with the aid of petrographic polarizing light microscope. Papagoite is also usually found exhibiting vitreous to dull luster when viewed in reflected light of petrographic polarizing light microscopes for mineralogists or the ones used in the field of optical mineralogy. Papagoite crystals are most commonly found translucent in appearance. Papagoite is also known to crystallize in the monoclinic system of crystal formation. In optical mineralogy, the monoclinic system of crystal formation comprises crystals having three axes of unequal lengths. Two of which are usually found in a position that is oblique or not perpendicular to one another. However, both of which are commonly found perpendicular to the third axis. The crystal habit of mineral Papagoite as described in the field of optical mineralogy usually includes tiny flattened, elongated crystals sometimes formed into spherical aggregates and massive vein filling material when specimens are evaluated with the aid of polarizing light microscopes used in the field of optical mineralogy. Papagoite is most commonly found showing imperfect cleavage in only one direction which can be seen more clearly visible when viewed with the aid of polarized microscopes used in the field of optical mineralogy. The hardness measure of the mineral Papagoite when it is evaluated using the Mohs scale method is usually ranging from 5 to 5.5. Mineral Papagoite is most commonly found leaving a pale blue streak when rubbed on a white porcelain streak plate. The specific gravity measure of mineral Papagoite is approximately 3.3 grams per cubic centimeters, which is slightly above average for non-metallic minerals. Mineral Papagoite has limited association to ajoite, limonite, barite, aurichalcite, and shattuckite. The best field indicators of mineral Papagoite include locality, crystal habit, color, and associations. Papagoite notably occurs at several localities including New Cornelia Mine, Ajo District, Pima County, Arizona, USA and Messina, Transvaal, South Africa. Mineral Papagoite is usually found forming as a secondary mineral on slip surfaces and in veins in altered granodiorites.
