Understanding the Influence of Mantle Dynamics on Earth's Magnetic Field Throughout the Plate Tectonic Cycle

Explore the intricate relationship between mantle dynamics and Earth's magnetic field in this conference talk presented at the 2023 Magnetics Information Consortium (MagIC) Workshop. Delve into cutting-edge research that couples mantle convection and geodynamo simulations to understand how mantle processes influence the generation of Earth's magnetic field throughout the plate tectonic cycle. Learn about the latest findings on long-term variations in the geomagnetic field and their potential links to large-scale processes such as planetary evolution and mantle convection. Discover how 3D mantle convection simulations using ASPECT software predict heat maps at the core-mantle boundary, and how these maps are used as boundary conditions for geodynamo simulations. Gain insights into the systematic exploration of CMB heat flux patterns and amplitudes on the geodynamo, and their connections to paleomagnetic observables. The talk covers topics including paleomagnetic data assessment, mantle models, plate reconstruction, core-mantle boundary heat flux, and numerical geodynamo models, providing a comprehensive overview of this fascinating area of geophysical research.
