3-3-3-3-3-3-3-3-3-3-3-3-3 From: Shea Thomas <tomdansunvolcan@xxxxxxxx> Dear friends and colleagues, We are running a high temperature diffusion-related session and a workshop at Goldschmidt 2022 in Honolulu! You may have to hop between many sites to come here, but hopefully, the idea of spending time in beautiful Hawaiâ??i will provide you with all the activation energy needed. Get your abstract in quickly before we run out of vacancies. Consider using a time pun as well. Looking forward to seeing you all, Tom, Rebecca, and Kendra Goldschmidt *session 7e* (Theme: Mineral, Melt, and Fluid Chemistry): *The time is ripe: using element diffusion to characterize the nature and timescales of igneous processes from source to surface* Characterizing timescales, and therefore the rates of igneous processes is an overarching objective of petrology. Magmatic journeys through the earthâ??s crust involve complex histories and reactions occurring at timescales ranging from seconds to hundreds of thousands of years. These processes include but are not limited to mantle or crustal melting, melt accumulation, metasomatism, storage, cooling, (re)crystallization, remobilization, and in some cases, eruption at the surface. Minerals, influenced by surrounding melts and fluids, contain records of igneous phenomena in the form of diffusion-induced chemical gradients. In some cases, part of this temporal record is even preserved in glass, melt and melt/fluid inclusions. This session welcomes contributions that leverage element diffusion to investigate timescales and reaction kinetics relevant to minerals, melts, glasses, and fluids associated with igneous processes. We encourage efforts that marry theoretical, analytical, experimental, numerical, and geophysical approaches to better understand magma petrogenesis and kinetic processes at a wide range of temporal and spatial scales. *Conveners*: *Tom Shea* (University of Hawaiâ??i at Manoa), *Kendra J.

BUT WAIT, THEREâ??S MORE â?¦.. Goldschmidt (pre-conference) Workshop: *Learning Time: Diffusion chronometry applied to high temperature systems.* Dates: Saturday 9 and 10 July 2022 Format: On-site Cost: $190/participant Applications of diffusion chronometry (inverting concentration gradients created by element diffusion for time information) are soaring, providing brand new insights into timescales of magma genesis, fluid-melt-mineral reactions, crustal transport and storage, cooling and (re)crystallization, magma ascent, degassing, eruption and cooling both in terrestrial and extraterrestrial settings. Over the last two decades, our community has learned about the endless possibilities afforded by diffusion chronometry, and better defined and mitigated some of the caveats and limits of the technique. This workshop seeks to bring together researchers interested in (1) learning about the basics and applications of diffusion and (2) acquiring some modeling experience. We also warmly welcome researchers already familiar with diffusion chronometry to attend and share their knowledge and experience. In this two-day workshop, a series of lectures covering the fundamentals of diffusion, its application to natural high temperature systems, and analytical and numerical modeling basics will be complemented by â??practicalsâ?? where participants will get to set up their own diffusion models. *Workshop organizing team: Thomas Shea* (University of Hawaiâ??i at Manoa), *Sumit Chakraborty* (Ruhr-Universität Bochum), *Rebecca deGraffenried* (Ruhr-Universität Bochum), *Ralf Dohmen *(Ruhr-Universität Bochum), *Kendra J.
