Geochemistry and Pb isotopic proof for sources of heavy metal(loid)s in Late Cretaceous sandstones from Eastern Pontides (NE Turkey)
(Springer, 2021)Upper Cretaceous sedimentary rocks are widely exposed around Trabzon, Giresun and Gumushane in the eastern Pontides. The sedimentary rocks are mainly composed of sandstones and marls, and the thicknesses of these rocks ... -
Kıbletepe (Araklı, Trabzon) yöresindeki volkanik kayaçların petrografik, jeokimyasal ve maden yatakları açısından incelenmesi
(Gümüşhane Üniversitesi, 2013)Doğu Karadeniz Bölgesi'nde, Kıbletepe (Araklı, Trabzon) ve çevresindeki volkanik kayaçlar Geç Kretase yaşlı olup, tabanda bazalt, andezit ve piroklastları, bunların üstünde bulunan dasit, riyolit ve piroklastları ile bunları ... -
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 ... -
Late Cretaceous Arc Igneous Activity: The Eğrikar Monzogranite Example
(International Geology Review, 2018)The geochemical and Sr–Nd–Pb isotope properties, as well as the Laser Ablation Inductively Coupled Plasma and Mass Spectrometry (LA-ICP-MS) U–Pb zircon age, of Eğrikar Monzogranite in the eastern Pontides, are primarily ... -
Late Cretaceous arc igneous activity: the Erikar Monzogranite example
(Taylor & Francis Inc, 2018)The geochemical and Sr-Nd-Pb isotope properties, as well as the Laser Ablation Inductively Coupled Plasma and Mass Spectrometry (LA-ICP-MS) U-Pb zircon age, of Erikar Monzogranite in the eastern Pontides, are primarily ... -
Petrogenesis of Late Cretaceous A-type plutonic rocks from the Eastern Pontides Orogenic Belt (NE Turkey): constraints from zircon U-Pb geochronology, zircon Lu-Hf and whole-rock Sr-Nd-Pb-Hf isotopes
(Taylor and Francis Ltd., 2023)The Late Cretaceous magmatic history of the Eastern Pontides Orogenic Belt (NE Turkey) was generally characterized by common I-type and lesser A-type plutons in varying size and composition. Of these, A-type plutons from ... -
Source Rock Characteristics and Hydrocarbon Potential of Late Cretaceous Deposits in the Eastern Black Sea Region, NE Turkey
(Energy Sources, Part A, 2008)In this article, source rock characteristics and hydrocarbon potential of the late Cretaceous turbidite sequences in the eastern Black Sea region were investigated. The total average organic carbon (TOC) contents of sequences ... -
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 ... -
Two-stage bimodal volcanism in a Late Cretaceous arc/back-arc setting, NE Turkey: Constraints from volcano-stratigraphy, zircon U–Pb and 40Ar/39Ar geochronology and whole-rock elemental and Sr-Nd-Pb isotope geochemistry
(Elsevier B.V., 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 ...
