Zircon U-Pb and Lu-Hf isotope study of the Neoproterozoic Haizhou Group in the Sulu orogen: Provenance and tectonic implications

► Zircon U-Pb age indicates that the deposition of the Haizhou Group was later than ~610 Ma. ► In situ Hf isotopic data indicates these rocks were derived from reworking of Paleoproterozoic to Archean crust. ► The results support the suture between the NCB and SCB is the B-Y Fault.
