Dynamic Connectors: How Boundary Layers Shape the Evolution of the Earth's Deep Interior
Mantle dynamics at different scales are influenced by boundary layer processes. The upper boundary affects subduction processes and driving of plate tectonics. The bottom boundary controls plume generation and is dynamically linked to deep thermochemical features, such as LLSVPs and ULVZs. Plumes rising from the bottom boundary layer sample the whole mantle and place their signature on Earth's surface, providing insight into mixing of chemical heterogeneities and the state of the deep mantle. The two boundary layers connect Earth's surface, core and mantle interior and govern their interaction. Understanding the dynamics in the boundary layers will help to link shallow and deep mantle processes.This session will explore the dynamics of boundary layers, including generation of subduction zones, plate tectonics, mantle plumes, and heat transfer, and the resultant surface observations that provide useful constraints. We welcome theoretical, experimental, and observational contributions from geodynamics, seismology, geomagnetism, mineral physics, petrology, and other disciplines.
