Overview of the Tectonic Evolution of the Sogut Metamorphics, Variscan Basement Assemblage of the Central Sakarya Terrane (NW Eskisehir, Turkey) Yasar, I. Dogancan; Sayıt, Kaan; Hames, W.E.; Koralay, Osman Ersin; Jeong, Y-J.; Göncüoğlu, Mehmet Cemal (2021-10-10)
Geological, mineralogical and geochemical characteristics of Mississippian K-bentonites from southern Turkey: A correlation with coeval tephras from Gondwana-derived terranes Bozkaya, Ömer; Günal Türkmenoğlu, Asuman; Göncüoğlu, Mehmet Cemal; Okuyucu, Cengiz (2021-09-01) Five thin (5–15 cm) and yellowish green tephra (K-bentonite) layers are exposed along two sections in the south of Akşehir (Konya, southern Turkey) within the Early Carboniferous (Mississippian) red dolomite-dolomitic lime...
Geochemistry and Zircon U-Pb Dates of Felsic-Intermediate Members of the Late Cretaceous Yuksekova Arc Basin: Constraints on the Evolution of the Bitlis-Zagros Branch of Neotethys (Elazig, E Turkey) Ural, Melek; Sayıt, Kaan; KORALAY, OSMAN ERSİN; Göncüoğlu, Mehmet Cemal (2021-08-01) During the Late Cretaceous in the Eastern Mediterranean, the northern branch of the southern Neotethys was closed by multiple northward subductions. Of these, the most northerly located subduction created the Baskil contin...
Geochemistry and U-Pb ages from the Kosdag Metavolcanics in the southern Central Pontides (Turkey): Complementary data for early Late Cretaceous island arc development in the Northern Neotethys BERBER, Faruk; Sayıt, Kaan; Göncüoğlu, Mehmet Cemal (2021-01-01) The Kosdag Metavolcanics (KMs) in the southern Central Pontides are exposed between the Izmir-Ankara-Erzincan Suture Belt in the south and the Sakarya Composite Terrane in the north. They comprise an approximately 40-km-lo...
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...
