The core-mantle boundary (CMB) region marks the bottom thermal boundary layer and the transition between the solid silicate mantle and the liquid iron outer core. The region influences and holds imprints of key dynamic processes including plume generation, slab foundering, and mantle convection, holding clues to the planet’s thermochemical evolution. It also hosts a variety of anomalous structures across a range of spatial scales. Yet, despite its global significance, it remains poorly understood due to its inaccessibility and complex physical properties. We invite multidisciplinary studies of the broader CMB region, including seismic imaging of ultra-low velocity zones and D″ structures, experimental and theoretical mineral physics under extreme conditions, high-resolution geodynamic modeling, and geochemical isotope insights.
