Comments:

Mineral of the group SCAPOLITE ( see also MEIONITE).
Marialite and meionite are found as masses or blocky crystals in a number of localities in the Grenville marble of Quebec and ontario (Canada). Sometimes (opaque white crystals from Otter Lake, Quebec) fluo red SW (activator: Fe) and white LW.

Activator(s) and spectrum:

Activator(s): Mn²⁺ , S₂^-,  Fe³⁺,  Eu²⁺,  O^-₂,  

Peaks in the spectrum (nm):

(O₂)^- replacing Cl^- (?) : weak band around 500nm
(S₂)^- replacing Cl^- (?) : another weak band around 600nm 
Mn²⁺  replacing Ca²⁺ (?) : peak at 700nm
Fe³⁺ replacing Al³⁺ : side band around 750nm

Best localities for fluorescence (*):

• Bancroft, Ontario, Canada (wernerite);
• Gooderham area, Haliburton Co., Ontario, Canada (weak red SW);
• Otter Lake, Quebec, Canada (wernerite) (bright yellow-orange LW, weaker SW);
• Franklin, New jersey, USA;
• Karur, Tamilnadu, India (red SW);
• Old Mine Park, Long Hill, Trumbull, Fairfield Co., Connecticut, USA (pink-lavender SW);
• Pitwak Mine, Koksha Valley, Khash & Kuran Wa Munjan Districts, Badakhshan Province, Afghanistan (pseodomorph after orthoclase, bright yellow LW);

(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
