Mantle convection drives the formation of plumes that advect mass and heat from the deep mantle toward the lithosphere. Simultaneously, subducting slabs facilitate volatile recycling, which, in tandem with volcanism, helps maintain a stable and clement atmosphere. While this overall picture appears to be clear, mantle dynamics involves processes and structures that remain poorly understood. These complexities include the influence of density and viscosity variations on the trajectory of plumes and slabs, the related dispersal of subducted materials in the mantle, the origin and evolution of deep thermo-chemical structures (e.g., LLSVPs, ULVZs) and their interactions with core and subducted slabs. Their investigations demand integration of constraints from traditional disciplines and innovative approaches like machine learning and integrated geodynamic simulations. This session invites contributions from geodynamics, mineral physics, seismology, global tectonics, igneous petrology, and geochemistry to explore the nature of mantle dynamics and heterogeneities and their surface geological expressions.
