5-5-5-5-5-5-5-5-5-5-5-5-5-5 From: Martin Mangler <martin.f.mangler@xxxxxxxxx> Dear Colleagues, We would like to invite you to submit an abstract to our session "Unravelling magma storage and ascent conditions using crystal textures" at IAVCEI 2025 in Geneva. Our invited speaker is Fabio Arzilli (University of Camerino). Submit your abstract here: https://sa2025.iavceivolcano.org/ <https://urldefense.com/v3/__https://sa2025.iavceivolcano.org/__;!!IKRxdwAv5BmarQ!Yl7PPRAuBP-KFkq-agovEHZbIg32F3YsnpYBAXElBcGdNgBLcwmIwBnvDGDiIkQpfSPLcf5ilrcXgMuWgmsKvOW7IQ$>. Our session is part of Theme 1. Abstract submission deadline is 20 December 2024. Session description: The crystal cargo of volcanic rocks provides one of the most direct windows into pre-eruptive magmatic processes and their timescales. In this session, we focus on crystal textures â?? i.e., crystal sizes, shapes, zoning, twinning, intergrowth, etc. â?? and what they can tell us about the conditions and timescales of magma emplacement, storage, remobilisation and ascent. We seek contributions that use crystal-scale textural observations to understand plumbing-system-scale processes, such as mush compaction, reactive porous flow, ascent-driven crystallisation and its effect on volcano explosivity. We welcome experimental studies on crystal nucleation, growth, and dissolution kinetics; microtextural case studies using traditional (e.g., universal stage) and modern (e.g., EBSD) methods; studies focussed on advances in 3D and 4D imaging; numerical models of crystallisation processes; and multidisciplinary studies featuring a textural component. Furthermore, we particularly encourage contributions studying the effects of crystal textures on magma rheology using analogue and numerical models.
