| Scope |
Characterization of the geophysical and geochemical interaction between minerals, fluid and magmatic liquid in subduction zone processes is central to our understanding of this environment. To this end, integrated observational, experimental, and theoretical studies are needed. Solubility and solution mechanisms of fluids in minerals and melts, and of silicate in fluids and linkages between solubility, solution mechanisms, chemical and physical properties of these materials under appropriate temperature, pressure, and redox conditions are needed.
This session will bring together scientists with focus on current experimental, theoretical, and observational understanding of
?how to model physicochemical properties of subducting slabs including
?spatial relation between intraslab seismicity such as slow-slip events and fluids pore pressure of fluids and their role in the weakening of shear strength of rocks
?accumulation and transfer of fluids and melts
?solubility measurements of minor elements, trace elements, and stable isotopes in aqueous fluids and melts,
?how water and oxide components in aqueous fluids govern element and isotope partitioning between fluid, melt, and crystalline materials, and
?linkages between solubility, partitioning, and rheological properties and solution mechanisms of water and silicate in minerals, melts, and fluids
