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 ...
Geochronology, geochemistry, and petrogenesis of the Eocene Bayburt intrusions, Eastern Pontides, NE Turkey: Evidence for lithospheric mantle and lower crustal sources in the high-K calc-alkaline magmatism
(Pergamon-Elsevier Science Ltd, 2015)
Eocene I-type plutons are widespread in the Eastern Pontides, Northeastern Turkey. Geochemical and isotopic results on two Eocene intrusive bodies located in the southern zone of the Eastern Pontides were utilized to achieve ...
Formation of the Egrikar (Gumushane) Fe-Cu skarn type mineralization in NE Turkey: U-Pb zircon age, lithogeochemistry, mineral chemistry, fluid inclusion, and O-H-C-S isotopic compositions
(Elsevier Science Bv, 2017)
The Egrikar Fe-Cu skarn type mineralization is located approximately 100 km NW of Gumuhane in NE Turkey. Geochemical analyses of diorite, which is thought to cause skarn, indicate medium K calc-alkaline (1.3 to similar to ...
Calc-alkaline I-type plutons in the eastern Pontides, NE Turkey: U-Pb zircon ages, geochemical and Sr-Nd isotopic compositions
(Elsevier Gmbh, 2011)
The Koprubasi intrusion from the eastern Pontides of NE Turkey consists of granodiorite and monzogranite, and contains a number of mafic microgranular enclaves (MMEs). We report here U-Pb zircon age, geochemical and Sr-Nd ...
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 ...
Trace and rare earth elements as indicators of provenance and depositional environments of Lias cherts in Gumushane, NE Turkey
(Elsevier Gmbh, Urban & Fischer Verlag, 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 ...
Petrogenesis of a Late Cretaceous composite pluton from the eastern Pontides: the Dagbasi pluton, NE Turkey
(E Schweizerbartsche Verlagsbuchhandlung, 2011)
Zircon U-Pb ages, major and trace elements, and Sr-Nd isotope data are reported for the Late Cretaceous Dagbasi pluton from the eastern Pontides, NE Turkey. This pluton has calc-alkaline affinity and displays typical ...
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 ...
Mescitli (Torul/Gümüşhane) ve Çevresindeki Eosen Yaşlı Volkanik Kayaçların Petrografik, Jeokimyasal ve Petrolojik Özellikleri
(2016)
Doğu Pontid'lerin Güney Zonunda Mescitli (Torul/Gümüşhane) ve çevresinde yüzeylenen Eosen yaşlı volkanik kayaçlar mineralojik, petrografik ve jeokimyasal olarak incelenmiştir. Mescitli volkanitleri bazaltik andezit, bazaltik ...
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 ...
