Comments:

Specimen not analyzed. should be strictly speaking labeled burbankite group (in the sense of Horvath – Lapis, Rivista 2000). Other possibilities for not analysed remondite(Ce) from MSH are petersenite-(Ce) and calcioburbankite. (Burbankite proper is not found in pegmatites.) ( Modris Baum on mindat)

Prismatic crystals of Remondite-(Ce) are slightly greenish and are apatite-like under lamp lighting. At day light they are slightly pinkish. This is typical scheme of dichroism for minerals, containing Ce3+ ion in absence of other chromophores. (Pavel Kartashov on mindat)

The remondite-(Ce) has strong REE absorption lines in the red/orange which helps distinguish it from elpidite found in the same environment. The lines are actually due to Nd – an indirect indicator for Ce.

Sometimes, well-formed xls are similar to (calcio)burbankite in form. ( Modris Baum on mindat)

Comments on spectrum and activators:

Laser-induced photoluminescence was studied for burbankite group mineralshexagonal burbankite, calcioburbankite, khanneshite and monoclinic remondite-(Ce), remondite-(La), petersenite-(Ce), as well as for orthorhombic carbocemaite and strontianite from carbonatites and hydrothennalites of alkaline complexes from various regions of the world.

Best localities for fluorescence (*):

• Poudrette quarry (Demix or Uni-Mix quarry  or MSH), Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada;

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