Simulation results for nominal abundance and fO₂ = ΔIW + 0 across all tidal power densities (see Section 2.3). The horizontal axis shows time [yr] since the Moon-forming impact on a logarithmic scale. Panel (A): evolution of the rheological front (vertical axis: mantle depth fraction). Panel (B): evolution of tidal dissipation for each case (vertical axis: cases). Dotted lines trace cumulative tidal energy dissipation; marker size scales with total dissipated energy. Solid lines indicate tidal heat-supported GRE. Black markers (∣) denote the time t_{V MR} at which we extract the volume mixing ratio for plotting in Figure 2. Note that the particular choice of t_{V MR} is arbitrary so long as it lies within the temporal range of GRE, indicated by the solid lines in the bottom panel. Crosses (×) mark mantle solidification (ϕ < 0.005).
