Petrography, mineral chemistry and crystallization conditions of cenozoic plutonic rocks located to the north of Bayburt (Eastern Pontides, Turkey)
(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 ...
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
(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 ...
Petrogenesis of the late Cretaceous Turnagol intrusion in the eastern Pontides: Implications for magma genesis in the arc setting
(China Univ Geosciences, Beijing, 2013)
A series of Cretaceous plutons is present in the eastern Pontides of northeastern Turkey. The Turnagol intrusion is the least studied and, thus, the least understood plutons in the orogen. This intrusion consists of ...
U-Pb zircon ages and petrogenesis of the Late Cretaceous I-type granitoids in arc setting, Eastern Pontides, NE Turkey
(Pergamon-Elsevier Science Ltd, 2021)
The Eastern Pontides Orogenic Belt (EPOB) as a well-preserved ancient magmatic arc situated in the eastern part of the Sakarya Zone and has key importance to allow for proper reconstruction of the geodynamic evolution of ...
Mineral chemistry and thermobarometry of Eocene monzogabbroic stocks from the Bafra (Samsun) area in Turkey: implications for disequilibrium crystallization and emplacement conditions
(Taylor & Francis Inc, 2014)
Monzogabbro stocks including felsic enclaves (monzosyenite) around the Bafra (Samsun) area at the western edge of the Eastern Pontides cut Eocene-aged volcanic and sedimentary units. The monzogabbros contain plagioclase, ...
Permo-Carboniferous granitoids with Jurassic high temperature metamorphism in Central Pontides, Northern Turkey
(Springer Wien, 2016)
In the northern part of the Central Pontides (N Turkey) there are different metamorphic rocks exposed, notably the Devrekani metamorphic rocks. Here, upper amphibolite-lower granulite facies metamorphic rocks contain ...
LA-ICP MS zircon dating, whole-rock and Sr-Nd-Pb-O isotope geochemistry of the Camibogazi pluton, Eastern Pontides, NE Turkey: Implications for lithospheric mantle and lower crustal sources in arc-related I-type magmatism
(Elsevier, 2014)
Late Cretaceous I-type plutons are widespread in the Eastern Pontides, NE Turkey. The studied Camibogazi pluton is a composite pluton consisting of diorite, tonalite, monzodiorite, monzonite, quartz monzonite, granite, and ...
Eocene I-type magmatism in the Eastern Pontides, NE Turkey: insights into magma genesis and magma-tectonic evolution from whole-rock geochemistry, geochronology and isotope systematics
(Taylor & Francis Inc, 2020)
The Eastern Pontides orogenic belt in NE Turkey hosts numerous I-type plutons of Eocene epoch. Here, we report new U-Pb SHRIMP zircon ages and in situ zircon Lu-Hf isotopes along with bulk-rock geochemical and Sr-Nd-Pb-O ...
Gölköy yöresi (Ordu, KD Türkiye) Eosen yaşlı I-tipi şoşonitik plütonların mineral kimyası, tüm-kayaç jeokimyası ve petrolojisi
(2018)
Doğu Pontidler Orojenik Kuşağı’nda (KD Türkiye), farklı boyut ve bileşimlere sahip Eosen yaşlı ortaç-felsik plütonlar yaygın olarak yüzeyleme vermektedir. Bunlardan, Eriko Tepe ve Göl Tepe Plütonları yaklaşık KB-GD ve D-B ...
Geochemical and Sr-Nd isotopic characteristics of post-collisional calc-alkaline volcanics in the eastern Pontides (NE Turkey)
(2011)
Doğu Pontidlerde Eosen yaşlı Torul volkanitlerinin ana, iz element, K-Ar yaş ve Sr-Nd izotop verileri incelenmiştir. İncelenen volkanitler, bazaltik andezit, andezit, trakiandezit ve az oranda da trakidasit ve bunların ...
