10 valid minerals.

Detailed Mineral List:

β“˜ Albite
Formula: Na(AlSi3O8)
β“˜ Beryl
Formula: Be3Al2(Si6O18)
Description: Beryl crystals are found in clusters in the poorly developed quartz core(s)
β“˜ 'Biotite'
Formula: K(Fe2+/Mg)2(Al/Fe3+/Mg/Ti)([Si/Al/Fe]2Si2O10)(OH/F)2
β“˜ 'Columbite-Tantalite'
Description: This material is likely columbite-Fe since this species is common in the Collins Hill formation and because these pegmatites contain substantial Fe.
β“˜ Fluorapatite
Formula: Ca5(PO4)3F
β“˜ 'Garnet Group'
Formula: X3Z2(SiO4)3
Description: Pegmatites contain substantial iron; therefore, this garnet may be almandine.
β“˜ Magnetite
Formula: Fe2+Fe3+2O4
Habit: Octahedral-dodecahedral
Description: Found in small pegmatite pods around the major pegmatite bodies.
β“˜ Meta-autunite
Formula: Ca(UO2)2(PO4)2 · 6H2O
β“˜ Muscovite
Formula: KAl2(AlSi3O10)(OH)2
β“˜ Opal
Formula: SiO2 · nH2O
β“˜ Opal var. Opal-AN
Formula: SiO2 · nH2O
β“˜ Quartz
Formula: SiO2
References:
Adam Berluti
β“˜ 'Tourmaline'
Formula: AD3G6 (T6O18)(BO3)3X3Z
Description: This material may be schorl based on the high Fe content of these pegmatites.
β“˜ Uraninite
Formula: UO2
β“˜ Uranophane
Formula: Ca(UO2)2(SiO3OH)2 · 5H2O
