Dear Colleagues,
On behalf of my co-conveners Drew Syverson and Wenhao Wang, I invite you to please consider submitting an abstract to 12g - Seafloor hydrothermal processes and their impacts on the modern and ancient Earthhttps://conf.goldschmidt.info/goldschmidt/2025/meetingapp.cgi/Session/7698 (session description pasted below). The 2024 Goldschmidt Conference will take place in Prague, Czech Republic, 6-11 July, and the abstract deadline is 26 February 2025. I hope that we can continue the tradition of this session as a forum for compelling hydrothermal geochemistry at the Goldschmidt conference. I look forward to seeing many of you there!
Best regards,
Ben, Drew, and Wenhao
12g - Seafloor hydrothermal processes and their impacts on the modern and ancient Earth
Seafloor hydrothermal systems have profoundly influenced Earth’s biosphere, lithosphere, hydrosphere, and atmosphere throughout Earth history and serve as crucial pathways for the transfer of materials and energy between the lithosphere and the exosphere (biosphere, hydrosphere, and atmosphere) today. Nonetheless, hydrothermal systems’ nature within the oceanic crust drastically limits the temporal extent of direct geologic observations of their existence. Thus, attempts to correlate seafloor hydrothermal processes with biological evolution, global elemental budgets, and global redox states throughout Earth history generally require interdisciplinary efforts that integrate studies of modern systems, interpretations of the geologic record, novel laboratory experiments, and numerical models. Specific focuses could include the role of seafloor hydrothermalism in carbon and other elemental cycles, studies of the linkages between high and low temperature hydrothermal alteration, crustal mineralogy, and seawater geochemistry, and the relation between hydrothermal systems and the tempos and milestones of biological evolution. Submissions from early career researchers are especially welcome.

Full session description:
Neutrons and X-rays are powerful probes for the study of structure, speciation and dynamics of minerals, rocks and geofluids, interrogating length scales from atoms to microns and characteristic time scales from pico- to microseconds. The weak interactions between neutrons and matter allow the study of large samples, and isotope contrast variation is commonly used to highlight specific features in complex samples. The emergence of new, powerful neutron and x-ray sources opens opportunities for novel studies of complex geochemical reactions and processes. Quantification and understanding of fluid behavior and fluid-rock reactions is important for optimization of large-scale geologic engineering processes such as natural gas and oil extraction from (un)conventional reservoirs, geologic carbon storage, and ion and contaminant transport. Using modern neutron and x-ray techniques, theory, and simulation tools, geochemical systems are studied with the goal of developing capabilities to predict rates of geochemical processes at the nanoscale and in upscaling and reservoir modeling.
This session will focus on new techniques and studies that help elucidate geochemical processes at all length and time scales. We invite paper submissions that highlight geochemical issues associated with mineral and rock reactions, rock characterization, transport of matter by hydrothermal fluids as well as solid-fluid interactions.
Thanks!
