A punchy read from @drjoshuashea.bsky.social - redefining mantle carbon

Skye-AVCEI - field teaching in 18degC and a gentle westerly. Sad not to make it to #IAVCEI2025 and catch up in Geneva. Doing what we can from here to think about magma and volcanos.

The typeset version of the 2022-2023 Fagradalsfjall paper is out, so let’s go over the main points of the paper 🌋

🚨🌋New paper on the geochemistry and petrology of the 2022–23 Fagradalsfjall eruptions on the Reykjanes Peninsula, Iceland. We study temporal variations in the magmatic plumbing system and link diffusion timescales to monitoring signals, tracing the timing of mush disaggregation and dike propagation

Amazing work by @albertocaracciolo.bsky.social . It's the coolest diffusion timescale work I've ever seen. You can see each eruption priming and how they are related to one another. Just super cool science.

There are many ways to study rocks up-close! 🔬💎 These thin section drawings and images are of feldspar-pyroxene xenoliths, brought up from beneath Fagradalsfjall, Iceland, by erupted basalts🌋 #ThinSectionTuesday #Petrology

My big paper on the 2021 Fagradalsfjall eruption is finally out! If you want to understand the recent eruptions on the Reykjanes Peninsula better, look no further: doi.org/10.1029/2024... Let’s dive in to what we found: 🧵 1/8

We are excited to announce our Department will be hosting a series of new #PhD studentships, starting from Oct 2025! 🥳 The studentships will be in the field of environmental science, working on topics at the heart of some of the most pressing societal challenges #EarthScience
