Early Cambrian S-type granites in the Sakarya Zone, NE Turkey: A record for transition from subduction to post-collisional extension deduced from U-Pb zircon age and Nd-Hf isotopes
Karslı, Orhan; Şengün, Fırat; Dokuz, Abdurrahman; Aydın, Faruk; Kandemir, Raif; Kristoffersen, Magnus; Santos, Jose Francisco; Hofmann, Mandy; Duygu, Levent (Elsevier, 2022)Cadomian realms have recently received much attention in the Alpine-Mediterranean orogenic belts, with discontinuous outcrops extending from the Alps to the Istanbul Zone, Menderes Massif, Taurides in Turkey and Iran as ... -

Late Jurassic Paleotethyan oceanic slab break-off revealed by Sr-Nd-Hf isotopes of Na-rich adakitic granites from northwestern Turkey
Karslı, Orhan; Şengün, Fırat; Santos, Jose Francisco; Uysal, İbrahim; Dokuz, Abdurrahman; Aydın, Faruk; Kandemir, Raif (Elsevier, 2021)The Mesozoic geodynamic evolution of the Paleotethys Ocean is critical but a poorly known piece of the geological history of the Sakarya Zone, north Turkey. Here, we describe new integrated research of zircon U-Pb ... -
Melting of the juvenile lower crust in a far-field response to roll-back of the southern Neotethyan oceanic lithosphere: the Oligocene adakitic dacites, NE Turkey
Karslı, Orhan; Caran, Şemsettin; Çoban, Hakan; Şengün, Fırat; Tekkanat, Osman; Andersen, Tom (Elsevier, 2020)Late Cenozoic tectono-thermal events and associated magmatism in the Sakarya Zone (SZ) are still contested. Although documented in the western part of the SZ, thus far, no magmatic activity has been identified in the eastern ... -
Silurian to Early Devonian arc magmatism in the western Sakarya Zone (NW Turkey), with inference to the closure of the Rheic Ocean
Karslı, Orhan; Şengün, Fırat; Dokuz, Abdurrahman; Kandemir, Raif; Aydın, Faruk; Andersen, Tom (Elsevier, 2020)The Rheic Ocean is the most significant Paleozoic ocean that detached peri-Gondwana terranes from the northern Gondwana margin throughout the closure of the Iapetus Ocean. the suture of the Rheic Ocean spreads from Mexico ... -
Tracking the timing of Neotethyan oceanic slab break-off: Geochronology and geochemistry of the quartz diorite porphyries, NE Turkey
Karslı, Orhan; Dokuz, Abdurrahman; Aydın, Faruk; Uysal, İbrahim; Şengün, Fırat; Kandemir, Raif; Santos, Jose Francisco; Andersen, Tom (Pergamon-Elsevier Science Ltd, 2020)The initiation of the break-off of the northern branch of the Neotethyan oceanic lithosphere is an important but poorly understood event in the geology of the Sakarya Zone (SZ) in northeastern Turkey. Although it is wellknown ...
