Comments:
Reported fluo from Langban but not Franklin.
In Jakobsberg, Sweden, wolastonite and margarosanite replace barysilite (see picture by Kjell Gatedal http://www.mindat.org/photo-241911.html )
Doubtfull luminescence; in Langban, Barysilite is mixed with svabite (fluo SW orange) and calcite (fluo red SW). Close observation of the xls of Barysilite from Langban seems to indicate that it is not responding to UV.
Main Activator(s) and spectrum:
No data
Best Locality for luminescence(*):
- Långban, Filipstad, Värmland, Sweden;
- Franklin Mine, Franklin, Franklin Mining District, Sussex Co., New Jersey, USA;
