Session Description:
The lower mantle is an enigmatic and important region of the Earth, comprising a significant volume of the planet and driving much of the dynamics observed on the surface. For example, the lowermost layer of this region serves as a boundary between the iron-rich core and the silicate mantle. As such, it sets the heat flux out of the core, effectively regulating convection in the greater mantle and the generation of the geodynamo in the core. Additionally, the lower mantle serves as a graveyard for subducted slabs and as a region of plume generation, making its chemistry uncertain and heterogeneous. This session focuses on the dynamics and evolution of this region, including (but not limited to) seismic observations, high-pressure mineralogy and chemistry of relevant materials, dynamic simulations and geochemical models and observations through time.
