Zircon U-Pb-Hf snapshots on the crustal evolution of the Serbo-Macedonian Massif; new insights from Ammouliani Island (northern Greece)

Zircon U-Pb and Lu-Hf isotope microanalysis was conducted in (meta)-igneous units of Ammouliani island to characterize crust-forming and reworking events in the Serbo-Macedonian massif. Zircon grains from an orthogneiss of the Vertiskos unit yielded a U-Pb crystallization age for the igneous precursor at 458.8 + or - 11 Ma with dominantly subchondritic epsilon Hf values indicating reworking of Neoproterozoic basement. A weighted mean epsilon Hf value of 0.7 + or - 2.4 from oscillatory zoned zircon grains of the Ouranoupoli granodiorite indicates juvenile crustal input at 52.1 + or - 0.6 Ma. The U-Pb-Hf zircon archive records discrete stages in the crustal evolution of the Serbo-Macedonian massif.
