Dear colleagues, We would like to invite you to submit an abstract to our EGU 2024 session that aims to investigate the impact of fluid-rock interactions on natural and subsurface engineering processes in diverse lithospheric settings. Conveners: Francesco Giuntoli, Sarah Incel, Oliver Plümper, Jesús Muñoz Montecinos At this link you find the description of the session: https://meetingorganizer.copernicus.org/EGU24/session/48682 The abstract deadline is 10 January 2024, 13:00 CET. We hope to see you numerous and wish you a nice weekend! Best regards, Francesco, Sarah, Oliver & Jesús *______________* *EGU 2024- Fluid-rock interaction: Kickstarter of metamorphic, deformation and subsurface engineering processes (TS1.8 - EDI)* Fluid-rock interactions play a pivotal role in shaping crustal dynamics and influencing subsurface engineering processes. These intricate interactions govern aspects such as deformation localization, earthquake genesis, and the emergence of metamorphic reactions and rheological weakening. These are critical not only for creating robust models of the solid Earth but also for advancing subsurface engineering endeavors like geothermal energy recovery, hydrogen storage and extraction as well as permanent carbon storage. As we navigate through the ongoing energy transition, enhancing these interactions for maximum geo-resource efficacy is a vital priority. The legacy inscribed within rock records paints a vivid picture of intricate interplay between mineral reactions, fluid flow and deformation—testaments to the often-intense nature of fluid-rock interactions. This session seeks multifaceted contributions to broaden our comprehension of fluid-rock interactions. We invite contributions that utilize an array of methodologies, ranging from natural observations, microstructural assessments, and geochemical analyses to rock mechanics, all intertwined with modelling techniques. This modelling can span from ab initio simulations to continuum scale simulations, ensuring a comprehensive exploration of fluid-rock/mineral interactions. Contributions that harness the power of artificial intelligence and its subsets are particularly encouraged.
