• 1. Published Eq. (2) contains a typo. The correct version of Eq. (2) should be:

  $${\ln(D}_{\text{Fe}2\text{O}3}^{\text{spl}/\text{melt}})=a\frac{10000}{T}+b+c\ln({C}_{\text{Fe}2\text{O}3}^{\text{spl}})$$

  (2)

  where T is temperature in Kelvin and ${C}_{\text{Fe}2\text{O}3}^{\text{spl}}$ is wt.% of Fe₂O₃ in spinel. Fits are a = 0.87 ± 0.07, b = − 4.6 ± 0.4, and c = 0.24 ± 0.02. We used the correct version of the equation in all our calculations, models, and figures; our results, discussion, and conclusions remain unchanged.

• 2. We did not provide the duration of the piston cylinder experiments. Each experiment had a run duration of 24 h after reaching the run temperature.

• 3. In the abstract, the line beginning, “If we allow ${D}_{\text{Fe}2\text{O}3}^{\text{opx}/\text{melt}}$ and ${D}_{\text{Fe}2\text{O}3}^{\text{opx}/\text{melt}}$ to also vary with temperature…” should instead be, “If we allow ${D}_{\text{Fe}2\text{O}3}^{\text{opx}/\text{melt}}$ and ${D}_{\text{Fe}2\text{O}3}^{\text{cpx}/\text{melt}}$ to also vary with temperature…”

• 4. The green and orange lines in Fig. 9 are mineral/melt partition coefficients estimated by Mallmann and O’Neill (2009) for ${D}_{\text{Fe}2\text{O}3}^{\text{cpx}/\text{melt}}$ and ${D}_{\text{Fe}2\text{O}3}^{\text{opx}/\text{melt}}$, respectively.
