Information - TS8.5/GD06.2/GMPV17 Tracing hydrothermal circulation at Mid-ocean ridges using geochemistry, geophysics and modelling
The circulation of seawater within the axial zones and flanks of mid-ocean ridges: (i) influences heat transport from the lithosphere to the hydrosphere; (ii) modifies the bulk and isotopic chemical composition of the oceanic crust and its physical properties (magnetism, porosity, density and seismic velocity) via fluid-rock interaction and the formation of secondary minerals; and (iii) alters the chemistry of seawater through the expulsion of high to low temperature hydrothermal fluids at various depths.
This session will bring together geophysicists, geochemists, mineralogists and modellers interested in the complexities of oceanic hydrothermal circulation. Within this broad remit, papers that aim to improve understanding of seawater circulation pathways through the oceanic crust and the role of hydrothermal cycling in heat, chemical and material fluxes between the lithosphere and the hydrosphere are particularly welcome.
