Re: Phosphorescent Calcite

Eu is enriched in the Petaca district rare minerals, but it is still pretty low. Most of the minerals have an average Eu2O3 of around 0.2%, as shown by microprobe analyses. Surprisingly, columbite has some of the highest concentrations of as much as 0.45%.
So your detection limit had better be pretty good.

We¡¯re talking about ppm concentrations not pure 100% Eu2O3 try that in a rock matrix Dud ?

Even the pro model XRF guns and cabinet machines go right for the Eu L lines:
