Metamorphic imprint of ridge subduction on the Neo-Tethyan ophiolites from the Saka Unit (Central Pontides, northern Turkey)
Frassi, Chiara; Rebay, Gisella; Marroni, Michele; Sayıt, Kaan; Göncüoğlu, Mehmet Cemal; Ellero, Alessandro; Ottria, Giuseppe; Pandolfi, Luca (2020-09-01)
The Intra-Pontide suture zone is the northernmost ophiolite suture zone exposed in the Anatolian peninsula. It consists of several variably deformed and metamorphosed tectonic units derived from the Neo-Tethyan IntraPontid...
Juvenile eucladid crinoid from the Middle Devonian of Turkey
Ausich, William; Göncüoğlu, Mehmet Cemal (2020-06-01)
A microcrinoid-sized eucladid crinoid (Eucladida Wright, 2017) is described from the Yiginli Formation (Devonian, Famennian) in the Buyuk Zap Anticline in the Hakkari region of SE Turkey. Compared to other eucladids of sim...
The Intra-Pontide ophiolites in Northern Turkey revisited: From birth to death of a Neotethyan oceanic domain
Marroni, Michele; Göncüoğlu, Mehmet Cemal; Frassi, Chiara; Sayıt, Kaan; Pandolfi, Luca; Ellero, Alessandro; Ottria, Giuseppe (2020-01-01)
The Anatolian peninsula is a key location to study the central portion of the Neotethys Ocean(s) and to understand how its western and eastern branches were connected. One of the lesser known branches of the Mesozoic ocean...
Improved methodology for identification of Goktepe white marble and the understanding of its use: A comparison with Carrara marble
Wielgosz-Rondolino, Dagmara; Antonelli, Fabrizio; Bojanowski, Maciej J.; Gladki, Marcin; Göncüoğlu, Mehmet Cemal; Lazzarini, Lorenzo (2020-01-01)
The provenance of marbles used for ancient statuary and architecture is of utmost importance for archaeologists, art historians and archaeometrists. The aim of this paper is to provide a comprehensive characterisation of t...
Integrated Radiolaria, benthic foraminifera and conodont biochronology of the pelagic Permian blocks/tectonic slices and geochemistry of associated volcanic rocks from the Mersin Melange, southern Turkey: Implications for the Permian evolution of the northern Neotethys
TEKİN, UĞUR KAĞAN; OKUYUCU, CENGİZ; Sayıt, Kaan; Bedi, Yavuz; Noble, Paula J.; Krystyn, Leopold; Göncüoğlu, Mehmet Cemal (2019-03-01)
Blocks and tectonic slices within the Mersin Melange (southern Turkey), which are of Northern Neotethyan origin (Izmir-Ankara-Erzincan Ocean (IAE)), were studied in detail by using radiolarian, conodont, and foraminiferal ...
U-Pb zircon geochronology of intrusive rocks from an exotic block in the Late Cretaceous - Paleocene Tarakli Flysch (northern Turkey): Constraints on the tectonics of the Intrapontide suture zone
Di Rosa, Maria; Farina, Federico; Marroni, Michele; Pandolfi, Luca; Göncüoğlu, Mehmet Cemal; Ellero, Alessandro; Ottria, Giuseppe (2019-03-01)
In the Boyali area (northern Anatolia), a thick succession of the Early Maastrichtian - Middle Paleocene Tarakli Flysch crops out. The Tarakh Flysch represents a foredeep sediment deposited during the final stage of collis...
New zircon U-Pb LA-ICP-MS ages and Hf isotope data from the Central Pontides (Turkey): Geological and geodynamic constraints
ÇİMEN, OKAY; Göncüoğlu, Mehmet Cemal; Simonetti, Antonio; Sayıt, Kaan (2018-05-01)
The Central Pontides in northern Anatolia is located on the accretionary complex formed by the closure of Neotethyan Intra-Pontide Ocean between the southern Eurasian margin (Istanbul-Zonguldak Terrane) and the Cimmerian S...
The Jurassic-Early Cretaceous basalt-chert association in the ophiolites of the Ankara Melange, east of Ankara, Turkey: age and geochemistry
Bortolotti, Valerio; Chiari, Marco; Göncüoğlu, Mehmet Cemal; Principi, Gianfranco; Saccani, Emilio; TEKİN, UĞUR KAĞAN; Tassinari, Renzo (2018-02-01)
This study is focused on slide blocks including oceanic lavas associated with pelagic sediments within the eastern part of the Ankara Melange. A detailed petrological characterization of the volcanic rocks and a detailed b...
Burial and exhumation history of the Daday Unit (Central Pontides, Turkey): implications for the closure of the Intra-Pontide oceanic basin
Frassi, Chiara; Marroni, Michele; Pandolfi, Luca; Göncüoğlu, Mehmet Cemal; Ellero, Alessandro; Ottria, Giuseppe; Sayıt, Kaan; Mcdonald, Christopher S.; Balestrieri, Maria Laura; Malasoma, Alessandro (2018-02-01)
In northern Turkey, the Intra-Pontide suture zone represents one of the first-order tectonic structures located between the Istanbul-Zonguldak and the Sakarya continental terranes. It consists of an E-W-trending assemblage...
Nd, Pb, Hf isotope characteristics and provenance of glacial granitic pebbles from Late Ordovician diamictites in the Taurides, S Turkey
