Fig. S1: P–XFe2O3 diagrams of (A) sample AR736 and (B) sample AR14, at 600 °C showing the strong impact of Fe2O3 on the stability of rutile and ilmenite. Note the absence of field without ilmenite and the absence of co-stability between plagioclase and rutile, except at very low XFe2O3 content.

Fig. S2: U-Th-Pb diagrams (208Pb/232Th vs 206Pb/238U) of samples AR736 (A) and AR14 (B). Error ellipses and uncertainties are ± 2σ level.
