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) 🌋

Join the RottnRock team and work with us on Hydrothermal Processes and associated Volcanic Hazards at Uppsala. Two postdoc positions have just opened: https://t.co/GTABxUpKPn
Pleased to announce that ROTTnROCK PI @LDR_Strasbourg won the VMSG Award 2025 @vmsg_uk! He'll present some of his work on hydrothermal alteration in Dublin! 🥳
🌋 Get ready for your #IAVCEI2025 Scientific Assembly in the beautiful Geneva, Switzerland!
🔬 This year, we are brining in 8 themes in volcanic research, 66 sessions to present your work, and 15 incredible workshops!
