Abstract

Detrital zircon ages from metasedimentary rocks of the Strandja massif have been used to reveal its tectonic history, initial position, and some aspects of the Paleozoic motion of this continental block within the Tethyan domain. The age of the metamorphic basement of northwestern Turkey has thus far been uncertain. Estimates of the depositional age of metasedimentary rocks range from Precambrian to late Paleozoic, hindering correlation of the massif with other tectonic units. In this study, new evaporation Pb-Pb ages of detrital zircons show that biotite schists constituting the central part of the metamorphic basement were deposited later than 430 Ma and prior to 315 Ma. Biotite schists exposed along the southern boundary of the basement were deposited between 300 and 271 Ma.
