Dear colleagues, Apologies for cross-positing. Just a reminder that there are only *5 days left* to submit an abstract for EGU. If your work relies on microstructural analysis to study petrological processes, please consider submitting your abstract to our session GMPV2.2 "*Rock microstructure as a tool for understanding igneous and metamorphic processes*". We have two excellent invited talks by Dr. Rüdiger Killian (Martin Luther University Halle-Wittenberg) and Dr. Marine Boulanger (Université Clermont-Auvergne). We hope to see you in Vienna this spring! Charlie, Thomas, Silvio, Martin and Zoja
