Thread: Unusual Subduction Processes - AGU '22 session: DI016

Dear Colleagues,

We invite you to submit contributions to our interdisciplinary session "Unusual Subduction Processes" (D1016). In this session, we invite contributions from all disciplines, including geodynamics, geophysics, geochemistry, field geology, and mineral physics in a common effort to advance the understanding of subduction processes and dynamics.

The AGU Fall Meeting will take place in Chicago, Illinois and online from December 12-16, 2022, with abstracts due August 3rd.

To submit an abstract to DI016, please go to:

Session Description:
Subduction drives plate tectonics, releases 90% of global seismic moment, governs the largest element recycling system, and shapes the Earth's surface. Despite progress in our understanding of subduction zones, important questions remain regarding subduction dynamics, especially in atypical subduction environments (e.g., complex slab geometries, interactions with the overriding plate, variable properties of the incoming subducting plate, and subducting-overriding plate memory). Further progress requires integrating observations from geochemistry, geophysics, field geology, and geodynamic modelling, as well as expanding the range of subduction zone investigations to include atypical examples. Unusual slab morphologies and processes such as slab tearing, lithospheric delamination, STEP fault propagation, and anomalous arc volcanism all highlight aspects of unusual subduction dynamics.

Invited Speakers:
-- Jonathan Delph (Purdue University)
-- Xiaowen Liu (University of Alberta)

We look forward to seeing you (either in person or virtually) in Chicago!

Cheers,
