β“˜ 'Lepidolite'
Colour: Pink to lavender
β“˜ Muscovite
Formula: KAl2(AlSi3O10)(OH)2
Description: Fine to medium grained plumose muscovite forms with albite-quartz-perthite footwall unit of the pegmatite that contains local concentrations of schorl.
β“˜ Quartz
Formula: SiO2
β“˜ Quartz var. Smoky Quartz
Formula: SiO2
β“˜ Schorl
Formula: NaFe2+3Al6(Si6O18)(BO3)3(OH)3(OH)
β“˜ Spodumene
Formula: LiAlSi2O6
Colour: Colorless
Description: Fragments of clear, colorless spodumene associated with gem-quality tourmaline.
β“˜ Swinefordite
Formula: Li(Al,Li,Mg)3((Si,Al)4O10)2(OH,F)4 · nH2O
β“˜ 'Tourmaline'
Formula: AD3G6 (T6O18)(BO3)3X3Z
β“˜ 'Tourmaline var. Rubellite'
Formula: A(D3)G6(T6O18)(BO3)3X3Z
Colour: Pink
Description: Many clear fragments of small crystals are present in the dumps, and some clear, gem-quality crystals as much as 4 inches in diameter and 15 inches long were recovered.
β“˜ 'Tourmaline var. Verdelite'
Formula: A(D3)G6(T6O18)(BO3)3X3Z
