About Beta-Willemite
Formula:
Zn2SiO4
Name:
Named by Arthur Schleede and Arno Gruhl in 1923 for a supposed second structural (metastable) state of willemite, a claim that was many years in verification. Taylor (1962) suggested that the mineral beta-willemite has essentially the same structure as willemite, but does show some structural abnormalities which still have not been well-defined. Beta-willemite does show anomalous yellow, rather than green, fluorescence in ultraviolet light and the implication is that the difference in the ultraviolet luminescence is related to subtle, but consistent, structural differences.
A variety of Willemite
A variety willemite that occurs as crusts of small, barrel-shaped crystals lining cavities in fault gouge cavities or solution cavities in regular willemite-bearing ore at the Sterling Mine, Ogdensburg, NJ. A fluorescent response of golden-yellow to orange versus green is a distinguishing characteristic.
