Commentaar:

From the White Knob quarry in the San Berardino Mts. CA, remarkable examples of orange or yellow-orange fluorescing wollastonite SW in blocky sections with orange-red fl. calcite SW and also red-fluorescing feldspar (species unidentified) of unusually high brightness. Information and help from Howard Brown and Lyman Hayes. Activator: Mn with Pb as coactivator?? Activator: probably Mn2+ substituting to Ca2+; also Fe3+ and Cr3+ found (Gaft).

In Jakobsberg, Sweden, wolastonite and margarosanite replace barysilite (see picture by Kjell Gatedal in bibliography )

Activator en spectrum:

Voornaamste Activator: Mn²⁺

Andere activatoren: Cr³⁺ , Fe³⁺ ,

Pieks in het spectrum (nm):

Mn²⁺_I repl. Ca²⁺_I : 555-560nm

Mn²⁺_II repl. Ca²⁺_II  : 580nm  

Mn²⁺_III repl. Ca²⁺_III : 603, 640nm

Fe³⁺ repl. Si⁴⁺ : 690-700nm

Cr³⁺ : narrow R-lines at 720nm + 794 - 840nm broad band

Cr³⁺_II : 794nm

Cr³⁺_III : 840nm  

Commentaar over activators en spectra:

Steady-state luminescence of wollastonite has been previously studied and luminescence of Mn²⁺, Fe³⁺ and supposedly Cr³⁺ has been proposed (Min’ko et al. 1978). (Gaft)
