Scope
|
Fluids on the surface and in the interior of the Earth may play crucial roles in terrestrial dynamics and evolution of a wide spectrum of phenomena in time and space, e.g., active tectonics such as earthquakes, slow fault slip, magmatism, hydrothermal activity to long-term orogeny with metamorphic complex and continental evolution. How much and where do fluids actually exist, and which evidence is sensitive? What are the fluid pathways and how fast do fluids migrate? How much do they reduce mechanical strength, induce rock failure, or enhance melting? Geofluids must carry various (but specific) chemical components. How much do they migrate and thereby contribute to formation of ore and continental crust? Geological, geophysical and geochemical methods are all necessary to address these questions, and we highly welcome various contributions from observational, experimental and theoretical approaches.
