U-Pb single zircon ages and geochemistry of metagranitoid rocks in the Cycladic Blueschists (Evia Island): Implications for the Triassic tectonic setting of Greece

► The largest metagranitoid suite in the Cycladic Blueschist unit was dated. ► U-Pb zircon dating yielded Late Triassic (234-214 Ma) ages of protolith intrusion. ► Geochemistry reveals an A-type affinity for the protolith of metagranitoid rocks. ► Late Triassic magmatism was possibly related to an anorogenic rift setting. ► Subsequent Alpine east-directed shearing took place at 450-500 °C and 65 + 15/− 10 MPa.
