DI11A:
Across the Scales: Earth's Mantle Dynamics through Space and Time I Posters


Session ID#: 10231

Session Description:
From small-scale convection underneath tectonic plates to huge thermochemical features such as the LLSVPs in the lower mantle, mantle dynamics is a multi-scale process! It includes everything from the cooling of the early magma ocean, to the formation of plumes, the assembly of supercontinents and the long-term secular cooling. Revealing how processes on these different temporal and spatial scales operate, interact, and produce surface observations in volcanism, tectonics, gravity anomalies and sea-level changes is thus of great importance for understanding Earth’s evolution and dynamics. This session aims to shed light on these processes, including (but not limited to) formation and dynamics of mantle structures, dynamics of plate tectonics and continental drift, and magma ocean dynamics. We welcome theoretical, numerical, laboratory and observational studies from a wide range of disciplines that contribute to understanding these multi-scale processes.
