Found the remnant of a satisfyingly cylindrical volcanic conduit off the coast of St Andrews, Scotland. You can see the basaltic columnar joints radiating out towards the cooling surface. You can also find some interesting phreatic deposits in this area. #KinkellNess

If you’re at #EGU26, come check out my talk on Wednesday at 15:10 where I’ll dive into supereruption magmatic plumbing and connectivity recorded by multiple phases.

Was such a treat to give a seminar at the USGS CalVO yesterday!

If giant supereruptions tapping rhyolites stored up to 1 GPa are more your cup of tea, come check out my second #AGU2025 talk tomorrow morning at 9:20am (352).

Come check out my AGU talk tomorrow at 4:15pm (350-351) on our rhyolite-MELTS modeling which illustrates highly efficient crystallization directly from basalt to rhyolite fueled recent volcanism at Córdon Caulle.

It’s a good day for exploring some wacky BSE zoning textures in feldspar.

Come check out my #IAVCEI2025 poster tomorrow afternoon (1.7.12; poster 25) to chat about complex supereruption plumbing systems and deep rhyolites!

New paper out! 🌋 We used rhyolite-MELTS in some unconventional ways on the spectacular Cordón Caulle system and learned that it is feasible that these rhyolites fractionated directly from a basaltic mush. Was such a fun project with great people.

In one step: Insights into shallow differentiation from basalt to rhyolite at Cordón Caulle from rhyolite-MELTS simulations

Magma mush systems are commonly invoked as the source from which crystal-melt segregation produces rhyolites, but these systems are rarely observed. T…
