I study how Earth’s mantle melts, moves, and shapes our planet’s volcanic history - and what that tells us about other worlds. 🌍🪐

Installation milestone reached! Our new 1300HR was turned on today for the first time. Meanwhile our guest Dr Joshua Shea from Cambridge is busy with the 7f, measuring trace element partitioning in olivine.

PhD students shouldn’t be in poverty. Simple as that.
The Universities Accord said #RaiseTheStipend, but nothing’s happened.
Tell parliament you want action!
📢 And tell everyone you know in Oz to sign as well❗️

This is a thin section of a leucitite from the El Capitan volcanic centre in eastern Australia. This specific thin section is very special, since it was the second recorded occurrence of lucite in Australia! Here is a short story on some cool samples I found. (1/5)

It has been a while since I worked on my fO2 calculator (available here fo2.rses.anu.edu.au), but now I have some available time to add fO2 for CO2-H2O mixtures, hopefully will finish early 2024. Hopefully will be super useful to the community!

I'll always be excited seeing zoning, inclusions, twinning in large phenocrysts. An added bonus was using the feldspars to observe offset in granite plutons.

An awesome couple of days checking out some metasomatised granites at Cligga Head, Cornwall
