Fluor-buergerite

This page is currently not sponsored. Click here to sponsor this page.
Martin J. Buerger
Formula:
Na(Fe3+3)Al6(Si6O18)(BO3)3O3F
Colour:
Bronzish-brown to dark-brown.
Crystal System:
Trigonal
Name:
Named for 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.
Originally named buergerite, but renamed as part of a nomenclature revision, because the type material is F-dominant (Henry et al., 2011).

Buergerite, i.e. the OH-dominant analogue, is currently not a recognised species.
