Scope
|
Recent advances of magnetotelluric and seismic imaging of the Earth's interior have suggested "geofluids" distribute more ubiquitously than ever thought; this has accelerated the development of a new integrated discipline on the geofluids ranging from material sciences in molecular scale to geophysics and geochemistry in the island arcs and mid oceanic ridges. The scope of this session is to bring together multi-scale and interdisciplinary researches on distributions of aqueous fluids and silicate and other melts in the crust and mantle of a wide range of tectonic settings, and on the physical and chemical properties of these fluids. Topics on geodynamics related to the presence of fluids are also welcomed.
