Advances in mantle convection and planetary evolution
Session ID#: 161679
Session Description:
Mantle dynamics involves complex rheological and material properties, which are difficult to constrain experimentally or model. It also couples in complex ways with the lithosphere, hydrosphere, atmosphere and even biosphere across a range of spatial and temporal scales. Therefore, constraining models of mantle dynamics requires careful integration with various geological and geophysical datasets that account for such complexities.
This session invites submissions using novel approaches to tackle these challenges. Examples include, but are not limited to, machine learning or surrogate approaches to massively accelerate forward modeling, inversion and data assimilation of fluid mechanics or material properties; high fidelity/high resolution analog experiments; coupled models of mantle evolution and surface processes; and data mining of hidden links between geological/geochemical/geophysical records and mantle dynamics. We encourage submissions that integrate advances from multiple disciplines, including geochemistry, mineral and rock physics, seismology, geomorphology and geodynamics.
