This session seeks to provide an integrated understanding of subduction zone processes, combining insights from global subduction zones with a detailed focus on the western margin of South America, one of the Earth's most significant subduction systems. While advancing a broad framework for the initiation, evolution, and dynamics of subduction zones globally, this session will also highlight distinctive features of the South American margin, such as its accretionary orogen, occurrences of flat-slab subduction, and its history of major seismic events. This presents an opportunity to examine a variety of processes, such as the generation and migration of volatiles and melts, seismic activity, magmatism, and crustal deformation.
We invite contributions from disciplines including geodynamics, geochemistry, petrology, volcanology, seismology, and geophysics to discuss subduction zone dynamics at all scales from the surface to the lower mantle, and in applications to natural laboratories, especially in relation to the Andes. With its broad focus, this session aims to foster interactions across traditional disciplinary boundaries.
