Very happy to share our latest paper on Kolumbo volcano! 🌋This research was only possible thanks to IODP, which has allowed for new insights into this highly hazardous volcano!

How the mantle melts ... (outside subduction zones) 🧪⚒️

Fantastic thread on understanding how the Earth's mantle deforms. 🧪⚒️🌍

Conques Cathedral is stunning. Also has: 1. Spectacular granite steps. 2. Unique, greyscale stained glass windows representing light but which also evoke highly layered metamorphic gneisses, schists, and migmatites of the local basement geology. 🧪⚒️
