Very well laid out presentation - thanks! What was the lateral spatial resolution of your LA-ICP-MS traverses? Could similar traverses have been obtained at higher spatial resolution by electron microprobe for the elements of interest?
Thank you Chloe. The spatial resolution of the LA-ICPMS traverses varies between 10 and 25 ?m. Indeed, one could obtain a higher spatial resolution by electron microprobe for major elements, Ba and probaply Sr.

Really interesting talk, thank you! In the TIS, how can you distinguish between magma rejuvenation from cannibalization of other feldspars during heating-cooling cycles (convective processes, not Ostwald ripening)? It appears that you favor magma rejuvenation (e.g. mass addition) versus thermal pulsing (more or less closed-system behavior) for the formation of these crystals, correct?
