Augelite is an aluminium phosphate mineral with formula: Al<sub>2</sub>(PO<sub>4</sub>)(OH)<sub>3</sub>. The shade varies from colorless to white, yellow or rose. Its crystal system is monoclinic.
It was first described by Christian Wilhelm Blomstrand for an occurrence in VästanÃÂ¥ iron mine at Scania, Sweden in 1868 and derives its name from the Greek ñÃÂóî in reference to its pearly lustre.
It occurs as a product of metamorphism of phosphate bearing peraluminous sediments and in high-temperature hydrothermal ore deposits. It occurs in association with attakolite, svanbergite, lazulite, hematite, trolleite, berlinite, rutile, pyrophyllite, baryte, arsenopyrite, stannite, pyrite, andorite, cassiterite and zinkenite.
