Frothy Xenolith (Xenopumice) have been found in several volcanoes in the Dessert of Saudi Arabia. What can they tell us about the underlying basement and how magma travels through it? Here our new article summarising our ideas:

At Galunggung in Indonesia 🇮🇩 🌋 the @ROTTnROCK team were investigating the impressive recent collapse within the crater - we found plenty of altered rocks in the blocky deposit!

In our paper, we propose a 2-stage model involving fractionation of basaltic magma in the mid-crust followed by assimilation of altered crust at shallow levels.

The basaltic rocks at Katla have fairly mantle-like oxygen isotope ratios whereas the silicic rocks have noticeably low ratios, suggesting they interacted with Icelandic crust with a modified oxygen isotope signature (low d¹⁸O crust) 🧵2/3

📣New paper about #Iceland in @AGU_GCubed. We report oxygen isotopes in rocks from #Katla volcano 🌋 and use the Magma Chamber Simulator 💻 to gain insight into silicic magma genesis in Iceland🧵1/3

Magnetite crystals at the El Laco deposit in Chile. At >5000 m elevation, El Laco is known for its spectacular lava flow-like deposits of magnetite (the crystals in the photo are ca. 1 cm across) 🌋

I don't often work with igneous rocks, but they do have cool microstructures, too!

Come and work with me, and the rest of the @ROTTnROCK gang to explore the stability of rotten volcanoes @LDR_Strasbourg @VOLCAPSE @MagmaProf
ROTTnROCK@ROTTnROCK
🌋🚨 Not one, but TWO PhD positions now recruiting in Dublin @UCD_Earth_Sci, supervised primarily by @claire_harnett1 - the projects will focus on modelling the effect of hydrothermal alteration on volcanoes. Deadline: 22nd January #findaphd

Some rotten rocks arrived at @LDR_Strasbourg from Indonesia today! These rocks will enter the first step of our synergistic workflow! 🌋

Honoured and thrilled to receive the VMSG Award @vmsg_uk! 😊 Looking forward to Dublin and my keynote lecture, which will *spoiler alert* be about hydrothermal alteration and volcanoes! 🌋 @ecole_terre

It’s that time where the geologists gather to eat pizza, prize giving and debrief the fun we’ve had all year long on field trips! 😊
