<font face="Calibri" class=""><span style="font-style: normal; font-size: 15px;" class="">Earth’s lower mantle regulates heat and material fluxes between the surface and the core. The chemistry and physics of this region play an important role in controlling
processes like Earth’s early differentiation into the mantle and core, evolution of geochemical reservoirs, fates of subducting slabs and rising plumes, and deep rock/volatile cycling. However, many questions remain about the long-term evolution of the lower
mantle and its present-day thermochemical structures, such as large low velocity provinces, ultra-low velocity zones, and regions of seismic anisotropy. Recent advances and future breakthroughs on understanding the lower mantle critically depend on the integration
of different fields. In this session, we invite contributions from geophysical explorations, geodynamic modeling, geochemistry, mineral-physics experimental and theoretical studies, as well as multidisciplinary approaches, to provide a platform for interdisciplinary
interactions, and thus to advance our understanding of the thermal and chemical status of Earth’s deep interior.</span></font></p>
