The Strandja Massif, Thrace Peninsula, NW Turkey, forms an important link between the Balkan Zone of Bulgaria, which is usually correlated with Variscan orogen in Central Europe, and the Pontides, where Cimmerian structures are the most prominent. The massif is composed of a Palaeozoic basement and a Triassic metasedimentary cover. The basement is made of various granite gneisses, paragneisses, and schists that are intruded by large plutons of monzonitic metagranites. Detrital zircon studies have revealed Ordovician (433 and 446 Ma) and Carboniferous (305 Ma) ages of the metasedimentary rocks. The isotopic age of the granite gneisses is 308-315 Ma (Carboniferous, Bashkirian-Moscovian) as single zircon evaporation method and conventional U-Pb technique show. The Palaeozoic basement was deformed and metamorphosed before the emplacement of the large monzonitic metagranite plutons yielding zircon ages from 309 +/- 24 to 257 Ma (Moscovian-Permian). Geochemical features of the Carboniferous and Permian magmatic rocks indicate a subduction-related tectonic setting similar to coeval rocks exposed in the Balkan zone of Bulgaria.
