Ar-40/Ar-39 dating of ignimbrites and plinian air-fall layers from Cappadocia, Central Turkey: Implications to chronostratigraphic and Eastern Mediterranean palaeoenvironmental record
Lepetit, Petra; Viereck, Lothar; Piper, John D. A.; Sudo, Masafumi; Gurel, Ali; Copuroglu, Ibrahim; Gruber, Manuela; Mayer, Bernhard; Koch, Michael; Tatar, Orhan; Gursoy, Halil (ELSEVIER GMBH, 2014)Magmatism forming the Central Anatolian Volcanic Province of Cappadocia, central Turkey, records the last phase of Neotethyan subduction after similar to 11 Ma. Thirteen large calc-alkaline ignimbrite sheets form marker ... -

Levent; Gursoy, Onder; Ayazli, I. Ercument; Cakmak, Rahsan; Belgen, Alpay; Yavasoglu, Hakan (ELSEVIER SCIENCE BV, 2012)The North Anatolian Fault Zone (NAFZ) is a 1200 km long dextral strike-slip fault zone forming the boundary between the Eurasian and Anatolian plates. It extends from the Gulf of Saros (North Aegean) in the west to the ... -
The efficacy of travertine as a palaeoenvironmental indicator: palaeomagnetic study of neotectonic examples from Denizli, Turkey
Mesci, Bekir Levent; Tatar, Orhan; Piper, John D. A.; Gursoy, Halil; Altunel, Erhan; Crowley, Stephen (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2013)This study has aimed to evaluate whether a discernible environmental signature is recorded in tectonic travertine by applying palaeomagnetic study to examples from the Denizli region in western Turkey. Palaeomagnetic ... -
The evolution of travertine masses in the Sivas area (Central Turkey) and their relationships to active tectonics
Mesci, B. Levent; Gursoy, Halil; Tatar, Orhan (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2008)Sicak Cermik, Delikkaya and Sarikaya are important travertine fields with active hot springs located 31 km west of Sivas. Based on their morphology, most of the travertines are classified as fissure-ridge travertines. ... -
Fossil findings from the Sicak Cermik fissure ridge-type travertines and possible hominid tracks, Sivas, Central Turkey
Mesci, B. Levent; Erkman, Ahmet Cem; Gursoy, Halil; Tatar, Orhan (TAYLOR & FRANCIS LTD, 2017)Sicak Cermik (Sivas) is an important geothermal and recent travertine formation area in Central Anatolia. The majority of travertines found in the region comprise fissure-ridge type travertines according to morphological ... -
Geophysical analysis of fault geometry and volcanic activity in the Erzincan Basin, Central Turkey: Complex evolution of a mature pull-apart basin
Akpinar, Zafer; Gursoy, Halil; Tatar, Orhan; Buyuksarac, Aydin; Kocbulut, Fikret; Piper, John D. A. (PERGAMON-ELSEVIER SCIENCE LTD, 2016)The Erzincan Basin is one of several Neogene sedimentary basins developed by prolonged right-lateral strike-slip along the North Anatolian Fault Zone (NAFZ), the intracontinental transform defining the present boundary ... -
New observations on the 1939 Erzincan Earthquake surface rupture on the Kelkit Valley segment of the North Anatolian Fault Zone, Turkey
Gursoy, Halil; Tatar, Orhan; Akpinar, Zafer; Polat, Ali; Mesci, Levent; Tuncer, Dogan (PERGAMON-ELSEVIER SCIENCE LTD, 2013)The 1939 Erzincan Earthquake (M=7.8), occurred on the North Anatolian Fault Zone (NAFZ), was one of the most active strike-slip faults in the world, and created a 360-km-long surface rupture. Traces of this surface rupture ... -
Palaeoearthquakes on the Kelkit Valley Segment of the North Anatolian Fault, Turkey: Implications for the Surface Rupture of the Historical 17 August 1668 Anatolian Earthquake
Zabci, Cengiz; Akyuz, Husnu Serdar; Karabacak, Volkan; Sancar, Taylan; Altunel, Erhan; Gursoy, Halil; Tatar, Orhan (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2011)The 26 December 1939 Erzincan (M-s = 7.8) and 20 December 1942 Erbaa-Niksar (M-s = 7.1) earthquakes created a total surface rupture more than 400 km between Erzincan and Erbaa on the middle to eastern sections of the North ... -
Palaeomagnetic and rock magnetic properties of travertine: Its potential as a recorder of geomagnetic palaeosecular variation, environmental change and earthquake activity in the Sicak Cermik geothermal field, Turkey
Piper, John D. A.; Mesci, Levent B.; Gursoy, Halil; Tatar, Orhan; Davies, Ceri J. (ELSEVIER SCIENCE BV, 2007)Travertine, the product of incremental growth of inorganic carbonate, is potentially a high-resolution recorder of geomagnetic palaeosecular variation (PSV) when it incorporates small amounts of ferromagnetic material. It ... -
Palaeomagnetic evidence for the neotectonic evolution of the Erzincan Basin, North Anatolian Fault Zone, Turkey
Tatar, Orhan; Akpinar, Zafer; Gursoy, Halil; Piper, John D. A.; Kocbulut, Fikret; Mesci, B. Levent; Polat, Ali; Roberts, Andrew P. (PERGAMON-ELSEVIER SCIENCE LTD, 2013)Ongoing motion of Anatolia towards the west is caused by convergence of the Arabian and Eurasian plates coupled with suction towards the retreating Hellenic Arc. This regime is controlling the development of neotectonic ... -
