Lepidolite from
Blue Jacket Tin Mine (Blue Jacket Reef), Dorchap Dyke Swarm, Mt Wills mining district, Omeo, East Gippsland Shire, Victoria, Australia
Locality type: | Mine | |
Classification | ||
---|---|---|
Species: | 'Lepidolite' (not an IMA approved species) | |
Comments: | Purple mica with ball-peen habit occurs both on the dumps and in outcrop. Grain size varies from a few mm to ~1.5cm. Maximum birefringence at 30 microns in thin section is second order, fitting with lepidolite and unlike the third order colours of muscovite at the same thickness. Pale green muscovite coexists with the lepidolite in some specimens. XRD analysis to distinguish from muscovite was inconclusive, however the association of habit, colour, and occurrence in a fractionated pegmatite, along with petrographic information indicates that the species is lepidolite. | |
Colour: | Lavender - purple of various intensity | |
Quality for species: | Good crystals or rich for species - important (!) | |
