We would like to draw your attention to an exciting session we are organizing this year at Goldschmidt in Chicago on the origin and dynamics of volatiles on Earth, other planets and planetesimals. Please consider submitting an abstract to our session and join us at Chicago on August 18th to 23rd . The deadline for abstract submission is March 29th.
Session 1d: The origin and dynamics of all volatiles on Earth, other planets, and planetesimals
Session description: Volatiles play a crucial role for establishing Earth’s unique mantle rheology and dynamics, its tectonic style, atmospheric composition, and overall its habitability. The volatile composition of a planetary mantle is a consequence of its accretion and differentiation, so it may hold important clues regarding the origin of a planet. On Earth specifically, surface-mantle exchange continues to modify the primordial budgets of mantle volatiles during Earth’ evolution untill present day. Similar processes widely occurring on planetesimals and other terrestrial planets may differ from those on Earth, but serve as important comparisons. We call for contributions on the origin, budget, and dynamics of volatiles in the mantle of Earth and other planets from a breadth of fields within planetary science. Through this session, we invite discussions on elemental and isotopic behavior of volatiles during processes of planetary growth, differentiation, and geological cycling. We invite contributions from all fields of planetary sciences, including but not limited to inclusion studies, isotope geochemistry, experimental petrology, and numerical modelling. Submission from early-career scientists and traditionally under-represented groups are strongly encouraged.
