T33B:
Fluid Migration Through Subduction Zones: Observations and the Consequences on Geodynamic Processes and Natural Hazards Posters

Submit an Abstract to this Session



Session ID#: 25865

Session Description:
Water plays a vital role in the Earth's evolution. At subduction plate boundaries, vast quantities of fluid are exchanged between the Earth, ocean and atmosphere; however, water transport through subduction zones is only partially understood. Volatile cycling is fundamental to the petrogenesis and eruption of arc magmas. Fluids and dehydration reactions may also play a key role in the earthquake cycle. This session will address some key scientific questions of volatile cycling. What is the role of the slab mantle as a vessel for transporting water into the subduction zone? What are the pathways of volatiles through the subduction system thereby impacting geodynamic processes (e.g. mantle flow)? How are volatile pathways manifested in seismic, volcanic and mineralization potential? We welcome contributions from a range of studies on diverse subduction environments from various disciplines (e.g., but not limited to: geophysical imaging, rock physics, geochemistry, geodynamic modelling).
