Petrogenesis and U–Pb zircon chronology of adakitic porphyries within the Kop ultramafic massif (Eastern Pontides Orogenic Belt, NE Turkey)
(Elsevier, 2012-12-30)
High-silica adakites intrude the Kop ultramafic massif in the eastern Pontide orogenic belt of NE Turkey. These dominantly dacitic to rhyodacitic plagioclase porphyries form clusters of small intrusions. U–Pb dating of ...
Petrographical, geochemical and petrological characteristics of Eocene volcanic rocks in the Mescitli area, Eastern Pontides (NE Turkey)
(2016-12)
Mineralogical, petrographical and geochemical data are presented for the Eocene aged Mescitli volcanics in the Eastern Pontides (NE Turkey). The studied rocks are composed of basaltic andesitic, andesitic, ...
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 ...
Trace and Rare Earth Elements as Indicators of Provenance and Depositional Environments of Lias Cherts in Gumushane, NE, Turkey
(Chemie der Erde,, 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 ...
Ordovician S-type granites in the western Sakarya Zone, NW Turkey; linkage to a back-arc setting
(Elsevier B.V., 2023)
Turkey's Early Paleozoic tectonic evolution has received much attention in recent years. Early Paleozoic intrusive rocks are mainly distributed across Europe, Turkey (İstanbul-Zonguldak Zone, Strandja Zone, and Tauride ...
Rock Slope Stability and Excavatability Assessment of Rocks at the Kapikaya Dam Site, Eastern Turkey
(Engineering Geology, 2008)
This paper describes the results of the engineering geological investigations and bearing capacity studies carried out at the proposed site of the rock fill Atasu Dam, to be constructed on basalts and pyroclastics. Rock ...
40Ar-39Ar age, petrography and geochemistry of the Yoncayolu Metamorphic Rocks (NE Turkey): Subduction-related metamorphism under greenschist facies conditions. N. Jb. Miner. Abh. (J. Min. Geochem.), 191, 3, 257-276(20), DOI: 10.1127/0077-7757/2014/0260.
(N. Jb. Miner. Abh. (J. Min. Geochem.), 2014-06)
Abstract: The Yoncayolu Metamorphic Rocks (YMR), exposed in the Sakarya zone (Erzincan, NE Turkey), consists mainly of greenschist rocks which are chlorite schists, muscovite-chlorite schists, metabasic rocks and lesser ...
Geochemical characterization of late Jurassic-early Cretaceous age limestones from Gumushane (NE-Turkiye): identification of the source of organic matter and paleo-environment conditions
(SPRINGER, 2022)
Samples from late Jurassic-early Cretaceous age limestones in five different areas in the Gumushane region (NE-Turkiye), were studied using TOC/Rock-Eval, and some trace elements analysis, to evaluate their organic material ...

(2017-12)
Mineralogical, petrographical and mineral chemistry properties are presented for the Cenozoic aged Bahcecik volcanics in the Eastern Pontides (NE Turkey). The studied volcanic rocks are composed of basaltic andesitic, ...
Post-Variscan autochthonous cover in the eastern Sakarya Zone, Turkey: Evolution of the late Carboniferous back-arc ocean to the Triassic Karakaya Ocean
(Elsevier Ltd, 2023)
The processes that caused removal of the upper Carboniferous to Permian sediments in the eastern Sakarya Zone, Turkey, are modeled by using of geochemical data and LA-ICP-MS U–Pb ages from detrital zircons. A felsic ...
