1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Carlo Pelullo <carlo.pelullo@xxxxxxx> Dear Colleagues, We would like to call your attention to the session *GMPV7.2-Magmatic crystals: Texture, chemical zoning, timescales and processes *at the upcoming *EGU** General Assembly 2025*, to be held in Vienna from *27 April to 2 May 2025*. This session proposes a comprehensive view of minerals as â??microscopic scale archivesâ?? of magmatic processes and welcome contributions aimed at decoding all the information that can be extracted from crystals, based on cutting edge and/or more traditional approaches, such as chemical zoning, isotopic systematics, geothermobarometry, experimental works, kinetic and numerical modelling. For details, please see session description below or at the link: https://meetingorganizer.copernicus.org/EGU25/session/54216 <https://urldefense.com/v3/__https://meetingorganizer.copernicus.org/EGU25/session/54216__;!!IKRxdwAv5BmarQ!YSLU4Q8tZEGzYaYDcKn7xpNkHVk-OXzWCXJ70VnbHzshP42L-gXfqVMeMclp3yBSXl38KQR30rQDhGjkil1ehWO7-Q$> The abstract submission deadline is the *15 January 2025, 13:00 CET. *Information on abstract submission can be found at: https://www.egu25.eu/programme/how_to_submit.html <https://urldefense.com/v3/__https://www.egu25.eu/programme/how_to_submit.html__;!!IKRxdwAv5BmarQ!YSLU4Q8tZEGzYaYDcKn7xpNkHVk-OXzWCXJ70VnbHzshP42L-gXfqVMeMclp3yBSXl38KQR30rQDhGjkil3DRw1HCg$> We invite you to submit an abstract and extend the invitation to all people who may be interested. Looking forward your contributions, All the best, Chiara, Helena and Carlo ________________________________________________________________ *Session details* Crystals offer crucial records of magmatic processes, allowing investigation of physico-chemical conditions during magma evolution and the magma pathways through Earth's mantle and crust. By analyzing crystal compositions and textures, it is possible to reconstruct the history of magma storage and transport, investigating specific processes, including fractionation, recharge, mixing, assimilation, and degassing. Advances in geochemistry and experimental petrology have improved our ability to investigate intra-crystal details and to correlate crystal textures and compositions with specific processes. Trace element variations during crystal growth carry significant information about magma compositions and conditions. Also, increasingly precise geothermobarometric models constrain crystallization conditions. Stable and radioactive isotopic systematics are employed, in both single-crystal and intracrystalline studies, in the investigation of magma genesis and evolution, alongside traditional dating techniques. Chemical zoning of major and trace elements in crystals can be related to changes in specific magmatic environments and the diverse compositional populations detected in minerals can record different magma dynamics and processes. Innovative methodologies allow investigation of kinetics on crystallization in the context of laboratory experiments on cooling and decompression of basaltic and felsic magmas, under a wide set of magmatic conditions. Finally, crystals can be used as chronometers, yielding insights into the timescales of magma ascent to eruption. Techniques such as diffusion chronometry provide valuable information on the duration of different magmatic processes, making them crucial tools for volcanic monitoring and eruption forecasting. This session proposes a comprehensive view of such â??microscopic scale archivesâ?? from natural cases, numerical modelling and experimental works. We welcome contributions using cutting edge and/or more traditional approaches suitable for decoding all the information that can be extracted from crystals. Interdisciplinary works using one or more of the above mentioned aspects are particularly welcome.
