Dear Colleagues, If you are interested in how fluids and melts interact with crustal and mantle rocks, we would like to draw your attention to the session “Journey into hot and deep fluid-rock interactions” (see description below; https://www.unica-wri-18.it/sessions-list/), which will be held at the 3rd IAGC International Conference Water Rock Interaction-18 & Applied Isotope Geochemistry-15, 17th – 21st June 2025, in Cagliari, Italy. We welcome contributions that focus on high-temperature processes in the lithosphere encompassing natural and experimental research in igneous and metamorphic petrology, mineralogy, microstructures, geochemistry, and geochronology. Invited keynote speaker: Márta Berkesi (HUN-REN Institute of Earth Physics and Space Science, Hungary) will speak about “Fluid-rock interactions in deep lithosphere at nano-, micro- and macroscale: complex geochemical, inclusion and modeling approach from the Pannonian Basin”. For more details on the conference, sessions, field trips, and abstract submission, please visit https://www.unica-wri-18.it/ Abstract submission deadline: 30th December 2024. We look forward to seeing you in the beautiful and sunny Sardinia (Italy) in June 2025! Bruna B. Carvalho (U.

Despite the common belief that predominant fluid-absent conditions govern in the deep lithosphere, a growing body of evidence shows that a wide variety of fluid species (not only melts, but also COH-fluids, and brines) may be present, impacting metamorphic reactions, petrological processes, and deformation. At greater depths, slab-derived fluids and melts in subduction zones interact with the lithospheric mantle, causing profound chemical changes. Therefore, quantifying the composition of fluids s.l. and understanding how they may influence metamorphism, anatexis, metasomatism, and deformation at different crustal and mantle levels is fundamental. Join us on this journey to unravel the role and importance of hot and deep fluid-rock interactions! We welcome contributions focused on high-temperature processes in the lithosphere through natural and experimental research on igneous and metamorphic petrology, mineralogy, microstructures, geochemistry, and geochronology.
