About HackmaniteHide

Victor Axel Hackman
Formula:
Na8Al6Si6O24(Cl2,S)
Name:
For Finnish geologist, Victor Axel Hackman [April 27, 1866 - 1941]. Professor at University of Helsinki (Helsingfors) and geologist with Finnish Geological Survey.
Pink to grey white to white variety of sodalite containing some S. Occasionally not enough S to be detectable with EDS (<1%). The S content can give sodalite reversible photochromism or tenebrescence. The fluorescent community reserve the name hackmanite for tenebrescent sodalites.

Originally described from Tawa valley, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia.
