Figure 3
A representative zircon with an inherited core. (a) CL image of a zircon rim and core with the U–Th and U–Pb ages, δ18O and εHf(t) analysis locations and data shown. (b) REE diagram for the zircon’s rim and core. (c) Plot of εHf(t) versus U–Pb age for the inherited cores. The εHf(t) values and ages of the geochemical reservoirs after Griffin et al.27, Blichert-Toft and Albarede28, Amelin et al.29. The ages and Hf–O isotopes of Spots 1 and 2 are consistent with C1@07 and C1@08 in Table S2, respectively. The age of Spot 3 is inferred from its Light-CL image, and the Hf–O isotopes of Spot 3 are consistent with TVG-C1@20 in Table S1.
