Dear Colleagues, We encourage you to submit an abstract to session 8h<https://conf.goldschmidt.info/goldschmidt/2024/meetingapp.cgi/Session/6411> “Exploring feedbacks between tectonically active systems and global biogeochemical cycles” at the upcoming Goldschmidt 2024 conference. This session aims to integrate the many aspects of tectonically active systems from terrestrial (i.e., hydrothermal) to marine (i.e., mid-ocean ridges, low temperature alteration of oceanic crust) and how they drive observed (bio)geochemical fluxes across spatiotemporal scales. Invited speakers: Dr. Ben Tutolo (University of Calgary) and Dr. Danielle Santiago Ramos (Rutgers University) Session description: Active and ancient volcanic provinces occupy a small portion of the Earth’s surface, but disproportionally impact biogeochemical fluxes of streams, groundwaters and oceans through enhanced water-rock interactions. The reactive nature of fluids and extrusive materials sourced from volcanoes and mid-ocean ridges translates into their rapid weathering and alteration. Volcanic gases and hydrothermal systems can increase weathering rates, thus amplifying the feedback between volcanoes and global biogeochemical cycles. Hydrothermal fluids facilitate the accessibility of critical metals through transport from deep in the Earth’s crust. Low temperature alteration of oceanic crust can modify ocean alkalinity over geologic timescales, thus playing an important role in the geologic carbon cycle. This session invites contributions from field, laboratory, and modeling studies that explore fluid-rock interactions in volcanic, geothermal and mid-ocean ridge systems, pedogenesis in volcanic soils, delivery of metal and nutrient fluxes from volcanic regions and modern or ancient observations to elucidate volcanic imprints on biogeochemical processes in the Earth’s history. Abstract submission<https://conf.goldschmidt.info/goldschmidt/2024/cfp.cgi> deadline is two weeks away March 29th. We look forward to receiving your submissions. See you in Chicago! Sincerely, Session Conveners Nicole Fernandez (Cornell University), Alida Perez-Fodich (University of Chile), Carolina Muñoz-Saez (Cornell University), and Yi Hu (ETH Zurich) _______________________________________ Nicole FERNANDEZ, Ph.D. (she/her) Assistant Professor Department of Earth and Atmospheric Science Cornell University, Ithaca, NY office: Snee Hall 2130 email: n.fernandez@cornell.edu<mailto:n.fernandez@cornell.edu> website: https://sites.coecis.cornell.edu/fernandezgroup/
