After a fair bit of frustration, our new excimer laser is installed! We have it coupled to an Element 2, and new laser plus sector magnet (rather than quadupole) mass spectrometry is a steep learning curve for me. Nice to spend the afternoon tinkering in the lab though.

The Bandelier Tuff (New Mexico) ejected perhaps 800 cubic km of magma and rock in two events a little over 1 million years ago.
Trace elements in #quartz make it glow in an electron beam (cathode luminescence). The outer bright blue rims in CL record crystallization temperatures (from Ti concentrations) abruptly 100°C hotter than before: magma recharge triggering a #supereruption.
Jack Wilcock's M.Sc. work (John Stix's group).

LA-ICP-MS is temporally wild. It somehow manages to be both incredibly fast (getting the data!) and incredibly slow (processing the data!). Staving of frustration by reminding myself that this is thousands of years of data, and if it takes a day to process, well that's still really, really, quick!

Kicking off #Goldschmidt2023 #Lyon with the #LAICPMS imaging workshop with Maurizio, Cipian, Mónica and Martin. Impressed to see how much this topic has improved in the last few years! 🌋
