A Tangled Web? Generation and Transport of Fluids, Volatiles, and Melts in Subduction Zones from Source to Surface I
Session ID#: 9802
Session Description:
We seek to integrate multidisciplinary efforts to advance our understanding of the generation and transport of volatiles and melts in subduction zones to further comprehend the deep volatile cycle and arc magma genesis. New geodynamic models and geophysical imaging techniques continue to improve our understanding of melt and fluid distribution in the mantle. Ground-truth evidence for these models and images is provided through geochemical, petrologic, geochronologic and field studies of lavas erupted on the surface, and the mantle and crust from which magmas are derived and through which they must pass. Thus the tangled web of sub-arc magmatic and volatile cycling is opening to provide a sharper view. This interdisciplinary session invites submissions from geochemistry, petrology, geophysics, modeling, experiments and field geology that address the temporal and spatial evolution of subduction outfluxes, evidence for sub-arc mantle wedge processes and geochemical exchange between Earth’s reservoirs.
