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 ± 11 Ma with dominantly subchondritic ϵHf values indicating reworking of Neoproterozoic basement. A weighted mean ϵHf value of 0.7 ± 2.4 from oscillatory zoned zircon grains of the Ouranoupoli granodiorite indicates juvenile crustal input at 52.1 ± 0.6 Ma. The U–Pb–Hf zircon archive records discrete stages in the crustal evolution of the Serbo-Macedonian massif.

塞尔维亚-马其顿地块地壳演化的锆石 U-Pb-Hf 快照：来自 Ammouliani 岛（希腊北部）的新见解

锆石 U-Pb 和 Lu-Hf 同位素微量分析在 Ammouliani 岛的（元）-火成岩单元中进行，以表征 Serbo-Macedonian 地块的结壳形成和改造事件。来自 Vertiskos 单元的正片麻岩的锆石晶粒产生了 458.8 ± 11 Ma 的火成岩前体的 U-Pb 结晶年龄，主要是亚球粒状 εHf 值，表明新元古代基底的再加工。Ouranoupoli 花岗闪长岩的振荡带状锆石颗粒的加权平均 εHf 值为 0.7 ± 2.4，表明幼年地壳输入在 52.1 ± 0.6 Ma。U-Pb-Hf 锆石档案记录了塞尔维亚-马其顿地块地壳演化的离散阶段。
