Session ID#: 24113

Session Description:
Understanding the processes controlling the transport of magmas and hydrothermal fluids through the oceanic lithosphere, and their feedbacks on its physical, rheological, magnetic and chemical properties, and habitability is crucial to comprehend the Earth system over time. This session focusses on the physical, hydrodynamic and geochemical mechanisms controlling mass and energy transfers during the formation and cooling of the lithosphere, from mid-oceanic spreading ridges to subduction zones with linkages and feedbacks between processes and the implications for Earth’s geodynamics, global geochemical cycle (including carbon and other volatile elements), life and marine mineral resources in the deep-sea. We encourage contributions on geological, geochemical and biological processes active at mid-oceanic ridge spreading centers and, more generally, in the oceanic lithosphere, from the observation of natural systems (e.g., ophiolitic complexes, dredged and drilled material from the oceanic mantle and crust), geophysics, flow and thermodynamic modeling and experimental works.
