Dear Colleagues, Apologies for cross-posting. We would like to draw your attention to our upcoming session at EGU 2026: GMPV10.2: Magmatic crystal textures and clocks: a mineralogical perspective into igneous processes Minerals are fundamental components of igneous (volcanic and plutonic) rocks. Variations in their textures and compositions are the results of magmatic and/or volcanic processes such as magma recharge and mixing, magma storage and crystallization, mush formation and remobilization, pluton growth and maturation, magma ascent, degassing, and syn-eruptive processes. These processes operate on timescales of minutes to millennia and unlocking the temporal information from various minerals provide complementary record of magmatic timescales. Minerals can also be used to reconstruct the original composition of the magma and its thermodynamic conditions, through modelling and experimental studies of elemental partitioning under magmatic conditions. This session offers a broad overview of these 'microscopic archives,' drawing on insights from natural case studies, numerical models, and experimental works. We welcome contributions related to volcanological, plutonic geochemical, experimental, and modelling studies of mineral textures and compositions with linkages to magmatic and volcanic processes and their timescales. Please note that the abstract submission deadline is 15 January 2026 at 13:00 CET. Here is the link to session description (with link to abstract submission): https://meetingorganizer.copernicus.org/EGU26/session/57801 Here are the instructions on how to submit an abstract: https://www.egu26.eu/authors/how-to-submit.html We hope that you will consider submitting to our session. Please do not hesitate to contact us for further information, and share with colleagues. See you in Vienna! Best wishes, Sri Budhi Utami, Helena Albert, Carlo Pelullo, Chiara Maria Petrone
