2-2-2-2-2-2-2-2-2-2-2-2-2 From: ANDREA DI CAPUA <andrea.dicapua@xxxxxx> Dear Everyone, Just a quick reminder about the new deadline to submit an abstract to the next IAS Congress (Wellington (NZ), 25-30 January 2026), considering our session titled "Relationship between volcanism and carbonate sedimentation on Earth and beyond" Session Description The interaction between volcanic and carbonate sedimentation is a fundamental process observed in both continental and marine environments. Spanning Earth's deep time, this interplay has been integral to sedimentary basin evolution, though its role is often underestimated in sedimentological studies. Geodynamic processes, especially those in continental rifts, have influenced long-term climate dynamics by mobilizing deep carbon reservoirs and driving atmospheric COâ?? oscillations. Large explosive eruptions normally disperse large volumes of particles that interact with sedimentary processes at different scales. Therefore, the influence of volcanic activity on carbonate deposits involves a complex interplay of physical, chemical, and biological processes that impact depositional environments and can drive key post-depositional transformations. In this regard, such interaction serves as essential (paleo)environmental proxies. In addition, volcanic sediments serve as vital nutrients in modern ecosystems, supporting diverse biological and biomineralization processes (including carbonate minerals). By examining case studies from ancient and modern settings, this session is dedicated to exploring the dynamic interplay between volcanic and carbonate sedimentation, emphasizing mechanisms through which volcanic activity impacts carbonate production, sedimentation, preservation, and lithification, and vice versa. Particular attention will be given, but not limited to how this interaction creates unique lithofacies with peculiar diagenetic processes, influences geochemical signatures, develops key stratigraphic features, and controls reservoir properties in hydrocarbon and geothermal systems. Contributions addressing similar interactions on Mars and other planetary bodies are also welcome. Submit your abstract by the 30th of May. See you in Wellington! Ciao!
