Dear all, We would like to invite you to submit an abstract to our AGU session P043: Volatiles and Volcanism Across the Solar System ( https://agu.confex.com/agu/agu24/meetingapp.cgi/Session/226847). *Session Description: *Volcanism and outgassing of volatiles (H, C, S, N, etc.) from planetary bodies across the solar system played a critical role in the evolution of planetary interiors, surface properties, atmospheres, and climate. The volcanic landforms, eruption styles, and the longevity of activity vary significantly across the solar system due to differences in temperature, composition (particularly bulk volatile contents), redox state, and lithospheric architecture, reflecting different thermal histories and internal dynamics of different planetary bodies. This session discusses recent advances in planetary volcanism (including silicate and cryovolcanism) relating to volatile behavior, magma generation, storage, ascent, and emplacement styles. We also encourage perspectives from studies of planetary surface properties and composition, age constraints, and analog terrestrial field studies, all leading to a better understanding of planetary volcanic records. We invite studies employing interdisciplinary approaches, including remote sensing, in-situ/meteorites or returned sample analysis, field observations, numerical/thermodynamic modeling, and laboratory experiments. *Invited speakers:* James Dottin, Brown University Michael Sori, Purdue University *Deadline*: 31st July 2024 Best, The session conveners: Shuo Ding, Lamont-Doherty Earth Observatory Pranabendu Moitra, University of Arizona Megan Newcombe, University of Maryland -- Megan Newcombe <https://www.geol.umd.edu/megannewcombe> (she/her) Assistant Professor University of Maryland
