About HackmaniteHide

Victor Axel Hackman
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 photochrome 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.
Hackmanite shows orange colored photoluminescence in UV light, exhibits a purple-red colour subsequently to UV irradiation or after cracking, bleaches within minutes to hours in visible light, and usually recovers colour in darkness (Goettlicher et al., 2013).

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