Replication Data for: Double-diffusive layering during the evolution of planetary mantles

Key Points: <strong>Layering in Planetary Mantles</strong>: Degree of layering during planetary mantle evolution is a key issue, especially since seismic discontinuities were observed in Earth's mantle. <strong>Seismic Discontinuities and Phase Transitions</strong>: Observations correlate mantle seismic discontinuities with phase transitions in mantle minerals, affecting geochemical profiles in mantle-derived basalts (MORBs and OIBs). <strong>Double-Diffusive Layering</strong>: The study investigates double-diffusive layering in fluids with temperature-dependent viscosity, relevant to mantle material. <strong>Influence of Initial Composition Gradients</strong>: Examines how initial compositional gradients impact thermal and chemical evolution in planetary mantles. <strong>Numerical Experiments and Layer Formation</strong>: Experiments show that self-organized layers form through dynamic fractionation across a range of conditions, suggesting this as a generic mantle process. <strong>Implications for Chemical Reservoirs</strong>: This model offers a dynamic explanation for the formation of distinct chemical reservoirs throughout planetary mantle history.
