Figure S2. Spatial and temporal influence of Pacific subduction on South China: Geochemical migration of Cretaceous mafic-intermediate rocks

Fig. S2: Age– εHf_(t) (a) and δ¹⁸O (b) for the Cretaceous mafic-intermediate igneous rocks in the southeastern SCB. The field of mantle-like zircon δ¹⁸O value (6.5-4.5 ‰) is from Valley et al. (1998). Geochemical data of the Cretaceous mafic-intermediate igneous rocks are listed in Table S3.
