Thanks for this very interesting presentation. It seems that Li isotopes fractionation is linked to fractional crystallisation. Is there any way to use this technique to track the origin of fluids involved in pegmatite formation as well ?

Many thanks for the presentation, this is really interesting. Did your CL work enable you to identify more than one generation of quartz in individual samples? And if so, could this be linked to different Li isotope populations?

Very nice results! Fluid inclusions are very abundant in pegmatite quartz and can have high Li contents, orders of magnitude higher than quartz. I am wondering how do you prevent contamination from fluid inclusions during SIMS analysis?
