Comments on spectrum and activators:
Green luminescence due to Uranium in traces (typical spectrum of uranyl).
Gunnel (1939) has studied the luminescence of natrolite from Oberschaffhauser, Germany (yellowish-white LW). Probably published in The Mineralogist at this time.
Best localities for fluorescence (*):
- Poudrette Quarry, Mont St Hilaire, Rouville County, Quebec, Canada;
- Ilimaussaq complex, Kvanefjeld, Narsaq, Kitaa (West Greenland) Province, Greenland;
(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
