Dear friends and colleagues,

Please consider submitting an abstract to our AGU session:

MR011 - The History of Volatiles in Rocky Planetary Interiors and Their
Surface Expression

(https://agu.confex.com/agu/fm22/prelim.cgi/Session/157196)

The AGU fall meeting will be held on Dec 12-16, 2022, in Chicago, USA &
Online. Deadline for abstract submission is August 3rd, 2022.

Session description:
Highly volatile elements (e.g., H, C, N, S) are critical for the internal
dynamics and surface environment of rocky planets and essential for life as
we know it. During accretion and solidification, the delivery,
partitioning, and loss of these volatile elements in rocky planetary
interiors set the initial conditions for their subsequent evolution. After
planet formation, their distribution, storage, and cycling between interior
reservoirs (core and mantle) and near-surface/surface reservoirs (crust,
ocean, atmosphere) regulate material circulation and thermal evolution of
the interior as well as tectonics and climate of the surface. This session
aims to bring together observational, experimental, and theoretical
contributions about the history of highly volatile elements in rocky
planetary interiors, with an emphasis on implications for the surface
environment and habitability of the Earth and other rocky planets within
and beyond the Solar System.

Invited presenters:
Claire Marie Guimond (Cambridge,
https://www.esc.cam.ac.uk/directory/claire-guimond)
Yoshinori Miyazaki (Caltech, https://yoshinori-miyazaki.people.caltech.edu)

Kind regards from the conveners:
Junjie Dong, Cara Vennari, Susannah Dorfman, Bin Chen, Jesse Gu

Dear Colleagues,

Please consider submitting an abstract to our AGU session:
DI005: From the surface to the deep interior of the Early Earth

Conveners:
Marion Garçon, CNRS-LMV (France)
Yoshinori Miyazaki, Caltech (USA) – Session mentee
Elizabeth Bell, UCLA (USA)
Denis Andrault, UCA-LMV (France)

Session description:
Despite a hellish environment implied by the word Hadean, an increasing
number of observations suggest that, relatively early in its history,
Earth had attained clement and potentially habitable surface conditions.
Solid Earth processes that operated during the first two billion years
are thus likely to be the keys to creating a habitable surface
environment on our planet. How early Earth’s geodynamics and tectonics
differed from those of the present day has long been a subject of study
and debate. This session welcomes abstracts that address new
theoretical, observational, and/or experimental constraints on crustal
and mantle evolution from the beginning of Earth’s history to the
Proterozoic. This includes, but is not limited to, studies related to
zircon records, mantle and crust geochemistry, petrology, mineral
physics, and theoretical and numerical modelling on mantle and crust
dynamics. We encourage interdisciplinary approaches, combining models
and observations from different fields, including studies discussing the
implications for the surface environment.

Abstract submission closes on August 3rd at 23:59 EDT

Kind regards from the conveners!
