Detailed Mineral List:

β“˜ Afmite
Formula: Al3(OH)4(H2O)3(PO4)(PO3OH) · H2O
β“˜ Beraunite
Formula: Fe3+6(PO4)4O(OH)4 · 6H2O
Description: Originally reported as beraunite, then changed to the now discredited 'eleonorite' around 2016, now restored as beraunite, 2021. IMA nomenclature revision (2021)
β“˜ Cacoxenite
Formula: Fe3+24AlO6(PO4)17(OH)12 · 75H2O
β“˜ Crandallite
Formula: CaAl3(PO4)(PO3OH)(OH)6
β“˜ Cryptomelane
Formula: K(Mn4+7Mn3+)O16
β“˜ Goethite
Formula: Ξ±-Fe3+O(OH)
β“˜ Hematite
Formula: Fe2O3
β“˜ Kobokoboite
Formula: Al6(PO4)4(OH)6 · 11H2O
β“˜ 'Limonite'
βœͺ Matulaite (TL)
Formula: (Fe3+,Al)Al7(PO4)4(PO3OH)2(OH)8(H2O)8 · 8H2O
Type Locality:
Habit: Crystalline encrustations
Colour: white
Description: Chemical analysis of samples as follows: P2O5 33.76 wt. % SiO2 0.22 TiO2 0.23 Al2O3 34.37 FeO* 0.79 MnO 0.12 ZnO 0.31 CaO 1.31 Na2O 0.18 K2O 0.03 Water accounts for the rest. FeO* is FeO total, there is most likely Fe2O3 present, probably almost exclusively. Multiply the FeO* by 1.1113 to obtain Fe2O3.
β“˜ Quartz
Formula: SiO2
β“˜ Rockbridgeite
Formula: Fe2+Fe3+4(PO4)3(OH)5
β“˜ Strengite
Formula: FePO4 · 2H2O
β“˜ Turquoise
Formula: CuAl6(PO4)4(OH)8 · 4H2O
β“˜ Wavellite
Formula: Al3(PO4)2(OH,F)3 · 5H2O
