Dear colleagues, We would like to invite you to submit an abstract to our session on " State-of-the-Arc: Questions and Progress about the Subduction Zone Factory (DI015)”. Session Description: The subduction of the oceanic lithosphere into the Earth’s interior is a fundamental geodynamic process that leads to some of the most catastrophic events known to man, from explosive volcanic eruptions and climate change to large magnitude earthquakes and tsunami. Understanding the fundamental processes that operate deep within subduction zones has been the focus of intensive research campaigns over the last few decades. Despite recent progress, important questions remain around, but not limited to, the importance of fluid-rock interactions to slab seismicity, mechanisms of slab-to-mantle material transport, controls on the decoupling-coupling transition and the thermal structure of the plate interface, and the fate of subducting slabs, their volatiles, and their interactions with the surrounding mantle. In this session, we will bring together expertise from a range of disciplines, including geophysics, geodynamics, petrology, geochemistry, and experimental laboratory studies to advance our understanding of subduction zone dynamics. Interdisciplinary contributions are highly encouraged. For more information or to submit your abstracts, please go to: https://agu.confex.com/agu/agu24/di/sessions/index.cgi?username=225552&password=434290 The deadline for submission is 11:59 pm, Eastern Time (USA), 31 July 2024. We look forward to seeing you at AGU 2024!
