Petrogenesis of post-collisional Middle Eocene volcanism in the Eastern Pontides (NE, Turkey): Insights from geochemistry, whole-rock Sr-Nd-Pb isotopes, zircon U-Pb and 40Ar-39Ar geochronology
Aydınçakır, Emre; Yücel, Cem; Ruffet, Gilles; Gücer, Mehmet Ali; Akaryalı, Enver; Kaygusuz, Abdullah (Elsevier GmbH, 2022)The debate about whether Eocene magmatism is considered to be post-collisional or subduction-related or not still continues. Here we offer new 40Ar-39Ar ad U-Pb zircon geochronology, mineral chemistry, bulk rock and Sr-Nd-Pb ... -
Petrogenesis of the late Cretaceous Turnagöl intrusion in the eastern Pontides: Implications for magma genesis in the arc setting
Kaygusuz, Abdullah; Sipahi, Ferkan; İlbeyli, Nurdane; Arslan, Mehmet; Chen, Bın; Aydınçakır, Emre (Production and hosting by Elsevier, 2012-09-28)A series of Cretaceous plutons is present in the eastern Pontides of northeastern Turkey. The Turnagöl intrusion is the least studied and, thus, the least understood plutons in the orogen. This intrusion consists of ... -
Petrographical, geochemical and petrological characteristics of Eocene volcanic rocks in the Mescitli area, Eastern Pontides (NE Turkey)
Kaygusuz, Abdullah; Şahin, Kübra (2016-12)Mineralogical, petrographical and geochemical data are presented for the Eocene aged Mescitli volcanics in the Eastern Pontides (NE Turkey). The studied rocks are composed of basaltic andesitic, andesitic, ... -
Petrography, mineral chemistry and crystallization conditions of cenozoic plutonic rocks located to the north of Bayburt (Eastern Pontides, Turkey)
Kaygusuz, Abdullah; Yucel, Cem; Arslan, Mehmet; Sipahi, Ferkan; Temizel, Irfan; Cakmak, Gokhan; Guloglu, Z. Samet (Maden Tetkik Ve Arama Genel Mudurlugu-Mta, 2018)The Eastern Pontides comprise many intrusive bodies varying in composition, size and age from Palaeozoic to Cenozoic. Especially Cenozoic aged bodies are commonly observed in the southern part, while they are rarely exposed ... -
The Sr, Nd, Pb and Hf isotopes and crystallization conditions of the middle Eocene Dadibi Pluton in the eastern Sakarya Zone, Turkey
Sipahi, Ferkan; Gücer, Mehmet Ali; Dokuz, Abdurrahman; Yi, Keewook; Kaygusuz, Abdullah; Akaryall, Enver; Doruk, Cüneyt; Saydam Eker, Çi dem (Cambridge University Press, 2023)Magmatic activity in the Sakarya Zone, an important segment of the Alpine orogenic belt, continues intermittently from the middle Carboniferous to Miocene. In this study, we provide geochronological and geochemical data ... -
Trace and Rare Earth Elements as Indicators of Provenance and Depositional Environments of Lias Cherts in Gumushane, NE, Turkey
Saydam Eker, Çiğdem; Sipahi, Ferkan; Kaygusuz, Abdullah (Chemie der Erde,, 2012)Trace elements and rare earth elements (REEs) of Lias-aged cherts in the Gumushane area were studied in order to understand their origin and depositional environment. Twenty three chert samples from five stratigraphic ... -
U-Pb geochronology, bulk-rock geochemistry and petrology of Late Cretaceous syenitic plutons in the Gölköy (Ordu) area (NE Turkey): Implications for magma generation in a continental arc extension triggered by slab roll-back
Temizel, İrfan; Arslan, Mehmet; Yücel, Cem; Abdioğlu Yazar, Emel; Kaygusuz, Abdullah; Aslan, Zafer (2019-01)Late Cretaceous felsic plutons in the Eastern Pontides orogenic belt of Turkey are found in varying ages, sizes and compositions. The Late Cretaceous syenitic bodies, namely Direkli and Yeniköy Tepe plutons in the Ordu ... -
U-Pb zircon chronology and petrogenesis of Carboniferous plutons in the northern part of the Eastern Pontides, NE Turkey: Constraints for Paleozoic magmatism and geodynamic evolution
Kaygusuz, Abdullah; Arslan, Mehmet; Sipahi, Ferkan; Temizel, Irfan (Elsevier, 2016)Numerous intrusive rocks of varying ages and compositions exist in the Paleozoic to Tertiary periods in the Eastern Pontides. Carboniferous intrusive rocks are commonly observed in the southern part of the Eastern Pontides. ... -
Zircon U-Pb geochronology and petrology of the tholeiitic gabbro from the Kovanlik (Giresun) area: Constraints for the Late Cretaceous bimodal arc magmatism in the Eastern Pontides Orogenic Belt, NE Turkey
Temizel, İrfan; Arslan, Mehmet; Aslan, Zafer; Eraydın, Tuğba Baki; Yazar, Emel Abdioğlu; Kaygusuz, Abdullah (ELSEVIERRADARWEG 29, 2022)Mafic intrusions of the Eastern Pontides Orogenic Belt (EPOB) in NE Turkey are found rarely in varying ages, sizes and compositions. Of these, tholeiitic gabbro stocks, namely Kovanlik gabbro, consist of pyroxene gabbro ... -
