Hi Dan, thanks for the great presentation. Might I ask what reference materials you are using? Thanks! - Cici

Hi Dan, congratulations for the breakthrough, you made it! Checking the Applecross Formation (never heard about it before), it makes amazing sense: your major peak at 1.2 Ga coincides with the Gardar Province in Southern Greenland. What is really nice is since it is an (per)alkaline province, zircon is pretty rare in such rocks, but K-fspar can be a major phase. Did you check the trace element composition of the detrital Kfspars along with the ages? Perhaps you can pick up the alkaline flavor of the 1.2 Ga age population...

In-situ dating in beta-decay geochronometer system is also possible by SIMS by analyzing doubly charged ions of the parent isotope. This has been done, for example, by Harrison et al. (2010) EPSL 299, 426-433, for 40K-40Ca dating. What do you think are the relative strengths and weaknesses of these two approaches?

What would the analytical set up for this technique be like for a lab that had obtained a collision cell MC-ICPMS, as in what kind of development time might they be looking at to set this technique up?
