2-2-2-2-2-2-2-2-2-2-2-2-2 From: "HUMPHREYS, MADELEINE C.S." <madeleine.humphreys@xxxxxxxxxxxx> Dear all, The deadline for abstract submissions to Goldschmidt 2023 is approaching, and we invite and encourage submissions on crustal magma mush systems through *session 4k:* *Crystal to crustal perspectives on mush systems and volcanic-plutonic connections*. https://urldefense.com/v3/__https://conf.goldschmidt.info/goldschmidt/2023/meetingapp.cgi/Session/4783__;!!IKRxdwAv5BmarQ!cPk3EEaDvqOCKp8MrYFm0WnrghAUOKIDoFqSWjLGS5o8XQeHfp0ehEh2Y3u5hzP9XGoKFURgaV94UiDF$ <https://urldefense.com/v3/__https://conf.goldschmidt.info/goldschmidt/2023/meetingapp.cgi/Session/4783__;!!IKRxdwAv5BmarQ!dRCJ9xHTuOenKia3WQH26ExGqOUBxuLqaGdnw3Y4pv8KW7xo5832ZHYlh4ECJvaVVPZLqrxI2rHRa_2viMOTV9U77FmyKAs$> Keynote speaker: Prof Marian Holness Invited speaker: Dr. Alexandre Carrara Plutonic and volcanic rocks provide complementary perspectives on crustal magmatism. Plutons give direct, but time-integrated, information on the system storage conditions, internal dynamics, and long-term history, while volcanic rocks provide higher resolution information about extrinsic parameters, volatile budgets, and temporal changes in the eruptible portion(s) of the systems. Overall, chronological data from plutons show that crustal magma reservoirs are fed and crystallised incrementally over long time periods. They likely contain large, vertically extensive regions of rheologically stiff crystal mush that should not be readily eruptible. However, these mushes can clearly be brought to eruptible conditions, sometimes in exceptionally large quantities, by mechanisms that may not be obviously recorded in plutons. The grain-scale distribution of melt, presence or absence of fluid, and the shapes of framework-forming crystals within these mushes, will affect the mush stability and therefore influence potential eruptibility and approaches towards mobilisation. In this session, we welcome multi-disciplinary â??crystal to crustalâ?? contributions to crustal magmatism, including experimental and numerical modelling approaches, perspectives on plutonic and volcanic rock records, and petrological, geochemical, textural, and field observations, in order to improve our understanding of the connections, architecture, timescales, and dynamics of melt-mush interaction in crustal magma systems. We look forward to seeing you in Lyon!
