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]}

Occurrence

Fluorwavellite was discovered in Silver Coin mine, Valmy, Humboldt County, Nevada, US.
