Eocene tonalite–granodiorite from the Havza (Samsun) area, northern Turkey: adakite-like melts of lithospheric mantle and crust generated in a post-collisional setting
Temizel, İrfan; Arslan, Mehmet; Yücel, Cem; Yazar, Emel Abdioğlu; Kaygusuz, Abdullah; Aslan, Zafer (Taylor and Francis Inc, 2020)Eocene intermediate to felsic plutons of different sizes and compositions are widespread in the Eastern Pontides Orogenic Belt in northern Turkey. Of these, the Taslik Tepe pluton in the Havza (Samsun) area is fine-to-me ... -
K-Ar dating, whole-rock and Sr-Nd isotope geochemistry of calc-alkaline volcanic rocks around the GumuAYhane area: implications for post-collisional volcanism in the Eastern Pontides, Northeast Turkey
Aslan, Zafer; Arslan, Mehmet; Temizel, İrfan; Kaygusuz, Abdullah (Springer Wien, 2014)Volcanic rocks from the GumuAYhane area in the southern part of the Eastern Pontides (NE Turkey) consist mainly of andesitic lava flows associated with tuffs, and rare basaltic dykes. The K-Ar whole-rock dating of these ... -
Mineral chemistry, whole-rock geochemistry and petrology of eocene ı-type shoshonitic plutons in the Golkoy area (Ordu, NE Turkey)
Temizel, İrfan; Abdioğlu Yazar, Emel; Arslan, Mehmet; Kaygusuz, Abdullah; Aslan, Zafer (Maden Tetkik ve Arama Genel Müdürlüğü-MTA, 2018)The Eocene intermediate to felsic plutons are widespread in varying sizes and compositions throughout the Eastern Pontides Orogenic Belt in NE Turkey. Of these, two monzonitic bodies (namely the Eriko Tepe and Gol Tepe ... -
SHRIMP U-Pb zircon ages and whole-rock geochemistry for the Sapc volcanic rocks, Biga Peninsula, Northwest Turkey: implications for pre-eruption crystallization conditions and source characteristics
Aslan, Zafer; Erdem, Dilber; Temizel, İrfan; Arslan, Mehmet (Taylor & Francis Ltd, 2017)Palaeogene and Neogene volcanic rocks are widespread on the Biga Peninsula of Northwest Turkey. These rocks were formed during the Eocene, Oligocene-Miocene, and late Miocene, and the early Miocene Sapc volcanic rocks in ... -
U-Pb geochronology, bulk-rock geochemistry and petrology of Late Cretaceous syenitic plutons in the Golkoy (Ordu) area (NE Turkey): Implications for magma generation in a continental arc extension triggered by slab roll-back
Temizel, İrfan; Arslan, Mehmet; Yücel, Cem; Yazar, Emel Abdioğlu; Kaygusuz, Abdullah; Aslan, Zafer (Pergamon-Elsevier Science LTD, 2019)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 Yenikoy Tepe plutons in the Ordu ... -
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; Yazar, Emel Abdioğlu; Aslan, Zafer; Kaygusuz, Abdullah; Eraydın, Tuğba Baki (Elsevier, 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 Kovanlık gabbro, consist of pyroxene gabbro and ...
