A full on but successful 4 days on the XFM beamline at the Ausgralian Synchrotron. We mixed things up this time by running some tree cores for Casey's PhD work - lots of cool features showing up! We also mapped a bunch of stalagmites, including some pilot data for my next job. 74 elemental maps made, a new record for us!

Box of rocks arrived for me today 😍 we will be taking these beauties to the Aus Synchrotron next month to get an idea if they might be suitable for #palaeofire research. Happily, these were collected by a friend of mine for her PhD, which means a potential collaboration with a friend (yay!), and the reuse of old samples rather than collecting new (double yay!).

Destructive analyses make me sooooo nervous, but I am looking forward to finding out how old these samples are! Hopefully the results will be worth the anxiety 😅
