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.

 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.
