Summary: Wolfeite (Fe,Mn)2PO4(OH) and barbosalite FeIIFeIII 2(PO4)2(OH)2 are the principal phases in phosphate pods from the core of a zoned altered granitic pegmatite at Thackaringa. Chemical analyses of the wolfeite show it to be Fe-rich and extends the triploiditewolfeite isomorphous series (Frondel, 1949) from ΣFe/Mn = 3·39 (this study) to greater than 100 (Clark and Couper, 1979).
