Therefore, examination of observed beneath the Pacific Ocean changes in the core/mantle boundary the reported breakdown by other experiments and Africa represent compositional or region. Incorporating a suite of important and computations is important. thermal anomalies compared with the processes, such as mantle melting, electronic Laboratory experiments and surrounding mantle. Some geodynamical spin transitions in iron-rich minerals, phase computations show that post-perovskite and seismological models now suggest that transitions and compositional variations exhibits greater seismic anisotropy than they could be purely thermal anomalies, with into one integrative framework for the lower perovskite. The anisotropy in the core/mantle distinct chemical compositions not required mantle remains a challenge for geophysicists boundary region might be caused by to explain the seismic data (Saskia Goes, over the coming decade. ❐ flow in the lowermost mantle, driven by Imperial College London, UK; Arwen Deuss, thermal or compositional heterogeneities, University of Cambridge, UK).
