Plots of (a) εHf(t) and (b) δ18O versus time for the Light-CL zircons and their inherited cores. The light grey dots represent global zircon εHf(t) (Roberts and Spencer43,) and δ18O data (Spencer et al.44). The vertical bars represent supercontinent amalgamation events35,36,44. The dotted ellipse denotes line is mark of the inherited zircons with ages outside of the ranges of the supercontinent amalgamation events.
