There is S in there too
When??mixed powdered rock with dil HCl ,some minor effervescence took place?
After attempting to dry,there was rotten egg smell suggestive of H2S
I tried??
casually heating and doping with sulfur,,..no change??
in glow intensity??

Zircon’s are noted for
hosting REE and the XRF shows that. The sodalite Cl is also seen in the XRF. The
optical spectra is a good match based on that paper.

Zircon coexisting with
florescent orange sodalite will give yellow florescense
This zircon
florescense is typically a broad yellow band at 575 nm
There??is a slope in this
region with both 405 nm and 365 UV excitation?
?
There are florescent
lines from 600 to 700 nm spectrum?
No ones??knows with certainty
what is causing this lines besides the possibility of REEs?
?
Work with synthetic
sodalite indicates that it is the presence of sulfur as a polysulfide which is
responsible for the fluorescence of sodalite.

Pics of florescent
close ups spectrum of 405 nm and 365 excitation and article?
Thanks?
