Home > Type Localities I – June 9 > MS1102 Fluor-buergerite


This is an unusual tourmaline group mineral originally called buergerite. The name buergerite honors Martin Buerger (1903-1986), professor at MIT and author of textbooks on X-ray crystallography (Donnay et al. 1966). The International Mineralogical Association added the fluor- prefix recently (Henry et al. 2011). Unlike most tourmaline group minerals, fluor-buergerite occurs in a rhyolitic environment, which causes it to unusually rich in fluorine. This is a single crystal, about 60% complete, of dark brown color. The crystal formed on a flat surface, and shows contacting on the back side. No damage.
