4-4-4-4-4-4-4-4-4-4-4-4-4 From: Chiara Maria Petrone <C.Petrone@xxxxxxxxx> Dear colleagues, We would like to draw your attention to the following session at Goldschmidt 2020. The abstract submission is open and the deadline is 14th February. 05c: From Mush to Magma: The Dynamics of Volcanic Systems and their Link with Volcanism <https://goldschmidt.info/2020/program/programViewThemes#session_471_4644> Conveners: Maren Kahl <https://goldschmidt.info/2020/userView?userId=33712>, Teresa Ubide <https://goldschmidt.info/2020/userView?userId=33713>, Chiara Maria Petrone <https://goldschmidt.info/2020/userView?userId=3618>, Kari Cooper <https://goldschmidt.info/2020/userView?userId=13175> Keynote: Adam Kent (Oregon State University) Understanding the dynamics of volcanic systems is fundamental to volcanic hazard assessment and forecasting volcanic eruptions. A major challenge is the ability to recognise if, when and how quickly a magmatic system can switch from a state of dormancy into a state of unrest or eruption. Despite the large body of geophysical information on magma migration and accumulation within sub-volcanic plumbing systems worldwide, there is currently no integrated view on how transcrustal mush-dominated systems evolve in space and time. The architecture of this magma reservoir system plays a central role in the dynamics of magma storage, mixing, transport through the crust, and triggering of eruptions. Understanding the dynamics requires coupling time scales with processes, and in magmatic systems is also closely coupled with temperature (and therefore crystallinity). Critically, eruption-triggering processes can unfold during the dormant state of a volcano, when signals of unrest in the shallow parts of its plumbing system can remain undetected. In this session, we welcome contributions aimed at improving our understanding of the dynamics of magmatic systems, combining inter- and multi-disciplinary methods that shed light on how, where and when key physical and chemical transitions from mush to magma occur. We also invite contributions that focus on the nature and conditions of magma storage and critical timescales (both radiogenic isotopes and diffusion related studies) that govern magma accumulation, transfer and re-mobilisation within transcrustal magmatic systems, thermal conditions of magma storage, barometry recording depths of magma storage and crystallization, and the fate of volatiles before and during major volcanic eruptions. Hope to see you all in Honolulu! 4-4-4-4-4-4-4-4-4-4-4-4-4 ------------------------------
