Dear Colleagues,

We welcome submissions for the following session at the 2018 AGU Fall Meeting in Washington DC:

T053: Volatile cycling in subduction zones: fluid inputs, pathways & outputs, and their impact on geodynamic processes and natural hazards
Water plays a vital role in the Earth's evolution. In subduction zones, vast quantities of fluid are exchanged between the Earth, ocean and atmosphere. Volatile cycling throughout the subduction system is fundamental to the petrogenesis and eruption of arc magmas, and may influence the earthquake cycle (e.g. dehydration reactions, slow slip). However, water transport into and through subduction zones is only partially understood, and observational evidence that quantifies fluid budgets and pathways remains elusive. This session will address key scientific questions of volatile cycling. What is the role of sediments and 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 and magmatic processes? How are volatile pathways manifested in seismic, volcanic & mineralization potential? We welcome contributions from all relevant studies on subduction zones, including, but not limited to: geophysical imaging, seismology, rock physics, geochemistry, petrology, geodynamic modelling.

Invited speakers:
Valentina Magni, University of Oslo
Tom Garth, University of Oxford

Cross-Listed divisions: Tectonophysics; Seismology; Study of the Earth's Deep Interior; Volcanology, Geochemistry and Petrology.
