U-Pb detrital zircon geochronology of the late Paleozoic–early Mesozoic sedimentary successions from the Belogradchik Unit in the West Fore-Balkan, NW Bulgaria

Year: 2024

Type: article

Abstract: U-Pb detrital zircon geochronology provides middle Permian–earliest Triassic (272–246 Ma) maximum depositional ages for the Zelenigrad and Vranska Formations of the Belogradchik Unit. These ages match the depositional span (305–249 Ma) of the sedimentary successions in the St. Iliya Heights of the Sakar-Strandzha Zone, in addition to their structural, textural and compositional similarities. The older zircon populations reveal erosion of Neoproterozoic basement, a feature characteristic for Gondwana-derived blocks. The gap between Cambrian and Carboniferous ages of the detrital zircon record of the Belogradchik Unit is ascribed to the Avalonia-type nature of the feeding provenance.
