Fluor-Buergerite - Mexquitic, San Luis Potosí, Mexico (TL) (#:MINS8766)

Dark chocolate colored crystals up to 1,4 cm of this uncommon mineral, belonging to the Tourmaline's family. Found at the end of the 60's, from its type locality.

Formula :
NaFe3^3+_Al6[F/O3/(BO3)3/Si6O_18_]

System: trigonal Hardness:7 Rarity:very rare

Name origin: Named in 1966 by Gaibriel Donnay, C. O. Ingamells, and Brian H. Mason, in honor of Martin Julian Buerger [April 8, 1903 Detroit, Michigan, USA - February 26, 1986 Lincoln, Massachusetts, USA], Professor of Mineralogy at the Massachusetts Institute of Technology and a pioneer of crystal structure analysis. He invented the X-ray precession camera permitting undistorted photography of the reciprocal lattice. He wrote many standard works concerning X-ray crystallography and was the PhD adviser for Harvard University mineralogist Clifford Frondel. It was renamed fluor-buergerite by Henry et al. (2011).
