Fluorwavellite

Fluorwavellite is a rare^[2] phosphate mineral with formula Al₃(PO₄)₂(OH)₂F•5H₂O.^[3] As suggested by its name, it is a fluorine-analogue of wavellite (hence its name), a rather common phosphate mineral. Chemically similar aluminium fluoride phosphate minerals include fluellite, kingite and mitryaevaite.^[4][5][6]
