A short update about the session 2i "Origins and planetary budgets of
volatile elements in the Earth's interior: accretion, degassing,
ingassing" at the upcoming Goldschmidt, Lyon, 4-9 July 2021 (France).
M. Hirschmann is the keynote speaker.
R. Fischer & D. Grewal will give invited talks.
*B. Marty, *recipient of the Goldschmidt award, will give a medal
lecture (45 min).
F. Gaillard, recipient of the Ringwood award, will give a medal
lecture (20 min).
Session Description (2i): The Earth’s surface, the mantle, and
possibly, the core, are major reservoirs for volatile elements (ie.
elements with a strong affinity for the gas phase). This session aims at
identifying the concentration and isotopic composition of these elements
in the Earth's reservoirs and how and when such volatile budgets were
set in the terrestrial planets. The initial volatile budgets in those
reservoirs and how they evolved in time has important implications for
understanding the genesis and evolution of planet Earth and other
planetary bodies (including the Moon). This, however, requires the
reconstruction of 4.5 Gyrs of geological processes involving volatiles.
These processes include the early and late planetary accretion, core -
magma ocean evolution, surficial degassing, atmospheric losses and deep
volatile transfers associated to the various styles of mantle convection
and, eventually, lithospheric recycling. To this end, we invite
contributions from all domains of planetary sciences, including, but not
limited to, analytical geochemistry, experimental petrology, numerical
modeling, and remote observations. Submissions from early career
scientists and underrepresented groups are strongly encouraged.
Conveners: Fabrice Gaillard, Alberto Saal, Lena Noack, Ali Bouhifd
You may already be aware that this meeting will be a hybrid format with
both onsite and online actions. T*he deadline for *abstract submissions
is February 26th and you will be asked, in addition to the classical
oral/poster choice, to specify whether your plan an onsite or online
contribution. At this stage however, this remains a flexible choice that
can be modified later, in spring.

Looking forward to seeing you at this exciting session and in the
beautiful city of Lyon.
Lena, Alberto, Ali and Fabrice.
