Development of the Middle Devonian-Mississippian carbonate platform in Zonguldak Terrane (NW Anatolia, Türkiye) with special emphasis on the Devonian-Carboniferous Boundary Okuyucu, Cengiz; Boncheva, Iliana; Sachanski, Valeri; Saydam-Demiray, D. Gülnur; Göncüoğlu, Mehmet Cemal (2025-01-01) The Zonguldak Terrane in the northwestern Türkiye is one of the continental micro-plates representing the eastern prolongation of the Variscan belt in Eastern Europe. Its distinguishing feature from the neighboring Varisca...
Pre-Alpine illitization ages from the Palaeozoic sequences of the Tauride Belt, Southern Türkiye: new data for a Late Palaeozoic event in northern Gondwana Bozkaya, Ömer; Uysal, I. Tonguç; Todd, Andrew; Yalçın, Hüseyin; Mählmann, Rafael Ferreiro; Okuyucu, Cengiz; Göncüoğlu, Mehmet Cemal (2025-01-01) Due to the effects of the Alpine orogeny, it is extremely difficult to obtain age data for pre-Alpine geological events for northern Gondwana. This study aims to study the metamorphism in Precambrian (Ediacaran) metaclasti...
Multi-stage tectonic record of the Central Sakarya Terrane Basement (NW Turkey): Implications for the Paleozoic evolution of Rheic Ocean and northern Gondwanan margin Yasar, I. Dogancan; Sayıt, Kaan; Miller, Brent V.; Hames, Willis E.; KORALAY, OSMAN ERSİN; Jeong, Youn-Joong; Göncüoğlu, Mehmet Cemal (2025-01-01) In northwestern Turkey, within the Central Sakarya Terrane, the Söğüt Metamorphics is one of the Variscan tectonic units preserved as a pre-Jurassic basement assemblage of the Sakarya Composite Terrane (SCT). It consists o...
CONODONT BIOSTRATIGRAPHY OF UPPER DEVONIAN TEPHRA BEARING DEPOSITS IN THE ISTANBUL-ZONGULDAK TERRANE, NW TURKEY: INSIGHTS ON THE KELLWASSER EVENTS Atakul-Özdemir, Ayşe; Türkmenoǧlu, Asuman Günal; Göncüoğlu, Mehmet Cemal; Bozkaya, Ömer; Okuyucu, Cengiz (2024-11-01) New evidence for a biostratigraphic assessment of the limestone succession comprising K-bentonite levels exposed in the Yilanli Formation of the Istanbul-Zonguldak Terrane are provided from conodonts at the Gavurpinari qua...
Tracing the protoliths of the garnet amphibolitic and retrogressed eclogitic slices and a conceptual tectonic model for their emplacement onto the Central Menderes Massif, Turkey: New geochemical data and laser ablation-inductively coupled plasma-mass spectrometry U-Pb zircon and rutile ages Gürsu, Semih; Möller, Andreas; Göncüoğlu, Mehmet Cemal; Toksoy Köksal, Fatma; Küçük, Aynur; Köksal, Serhat (2023-02-01)
Ancient white and grey marbles from Aphrodisias: multi-method characterization Wielgosz-Rondolino, Dagmara; Antonelli, Fabrizio; Bojanowski, Maciej J.; Degryse, Patrick; Gładki, Marcin; Göncüoğlu, Mehmet Cemal; Lazzarini, Lorenzo; Long, Leah; Mandera, Sara (2023-01-01) The paper presents the results of the archaeometric investigation, conducted for the first time with the use of a wide range of analytical methods, on white and grey marbles exploited in the so-called City and Regional Qua...
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...
