Temporal, geochemical and geodynamic evolution of the Late Cretaceous subduction zone volcanism in the eastern Sakarya Zone, NE Turkey: Implications for mantle-crust interaction in an arc setting
(Pergamon-Elsevier Science Ltd, 2020)The Late Cretaceous Artvin volcanic rocks (LCAVs) from the eastern Sakarya zone (ESZ) of NE Turkey are composed of mafic/basaltic (S1-catak and S2-caglayan) and felsic/acidic (S1-Kizilkaya and S2-Tirebolu) rock types that ... -
Tracking the birth and growth of Cimmeria: Geochronology and origins of intrusive rocks from NW Iran
(Elsevier, 2020)New geochronological and geochemical data for Late Neoproterozoic to Mesozoic intrusive rocks from NW Iran define major regional magmatic episodes and track the birth and growth of one of the Cimmerian microcontinents: the ... -
Tracking the timing of Neotethyan oceanic slab break-off: Geochronology and geochemistry of the quartz diorite porphyries, NE Turkey
(Pergamon-Elsevier Science Ltd, 2020)The initiation of the break-off of the northern branch of the Neotethyan oceanic lithosphere is an important but poorly understood event in the geology of the Sakarya Zone (SZ) in northeastern Turkey. Although it is wellknown ... -
Two-stage bimodal volcanism in a Late Cretaceous arc/back-arc setting, NE Turkey: Constraints from volcano-stratigraphy, zircon Usingle bondPb and 40Ar/39Ar geochronology and whole-rock elemental and Sr-Nd-Pb isotope geochemistry
(Elsevier, 2023)The eastern Blacksea magmatic arc (EBMA) in the eastern Sakarya Zone (ESZ) provides an excellent opportunity to investigate birth of an extensional intra-arc and back-arc settings in the Late Cretaceous over the Early ... -
Upper Campanian calciclastic turbidite sequences from the Hacimehmet area (eastern Pontides, NE Turkey): integrated biostratigraphy and microfacies analysis
(Polska Akad Nauk, Polish Acad Sciences, Univ Warsaw, Geology Dept, 2014)The upper Campanian (Cretaceous) of the Hacimehmet area (south of the city of Trabzon; Eastern Pontides) is mainly composed of calciclastic turbidites. the basinal unit of the 119 m thick succession includes thin red pelagic ... -
The Upper cretaceous calciclastic submarine fan deposits in the Eastern Pontides, NE Turkey: facies architecture and controlling factors
(2013)The Tonya Formation, which represents the uppermost part of the Mesozoic sequence in the Eastern Pontides, consists of calciturbidites in Trabzon and its surrounding region. Two stratigraphic sections of the unit were ... -
Volkanik tüf esaslı geopolimerlerin basınç dayanımına kür süresi ve sıcaklığın etkileri
(Gümüşhane Üniversitesi, 2021)Çimento klinkeri üretimi esnasında atmosfere salınan CO2 gazı sera etkisi nedeniyle küresel ısınmaya neden olmaktadır. Günümüzde bu durum çok tehlikeli boyutlara ulaşmış olup insan yaşamını tehdit eder hale gelmiştir. Bu ... -
Vulnerable geosites of cayirbagi-calkoy (Duzkoy-Trabzon) in the Eastern Black Sea region of NE Turkey and their geotourism potential
(Springer Heidelberg, 2019)Geotourism is a relatively new branch of tourism dealing with geosites, which are special places that exhibit aspects that characterize the complex history of the Earth. This contribution aims to report an inventory of ... -
What processes control the genesis of absarokite to shoshonite-banakite series in an intracontinental setting, as revealed by geochemical and Sr-Nd-Pb isotope data of Karadak Stratovolcano in Central Anatolia, Turkey
(Elsevier, 2019)The Latest Cenozoic absarokite to shoshonite-banakite series (ASB) samples were discovered in the Karadag stratovolcano (KS) which erupted in the Karaman basin in Central Anatolia, Turkey; and has a spatially close association ... -
Zircon Lu-Hf isotope systematics and U-Pb geochronology, whole-rock Sr-Nd isotopes and geochemistry of the early Jurassic Gokcedere pluton, Sakarya Zone-NE Turkey: a magmatic response to roll-back of the Paleo-Tethyan oceanic lithosphere
(Springer, 2017)The early Mesozoic was a critical era for the geodynamic evolution of the Sakarya Zone as transition from accretion to collision events in the region. However, its complex evolutionary history is still debated. To address ... -
Zircon U-Pb, geochemical and isotopic constraints on the age and origin of A- and I-type granites and gabbro-diorites from NW Iran
(Elsevier, 2020)The continental crust of NW Iran is intruded by Late Cretaceous I-type granites and gabbro-diorites as well as Paleocene A-type granites. SIMS and LA-ICPMS U-Pb analyses of zircons yield ages of 100-92 Ma (Late Cretaceous) ...
