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 ...
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 ...
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 ...
U-Pb geochronology, bulk-rock geochemistry and petrology of Late Cretaceous syenitic plutons in the Gölköy (Ordu) area (NE Turkey): Implications for magma generation in a continental arc extension triggered by slab roll-back
(2019-01)
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 Yeniköy Tepe plutons in the Ordu ...
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 ...
Mineral chemistry, crystallization conditions and petrography of Cenozoic volcanic rocks in the Bahçecik (Torul/Gümüşhane) area, Eastern Pontides (NE Turkey).
(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 ...
The Sr, Nd, Pb and Hf isotopes and crystallization conditions of the middle Eocene Dadibi Pluton in the eastern Sakarya Zone, Turkey
(Cambridge University Press, 2023)
Magmatic activity in the Sakarya Zone, an important segment of the Alpine orogenic belt, continues intermittently from the middle Carboniferous to Miocene. In this study, we provide geochronological and geochemical data ...
Natural Walls of Anatolia: formation and development of Dis Kayaliklari as a structural landform (Sivas, Turkiye)
(springerlink, 2023)
The Dis Kayaliklari is one of the largest and most striking examples of crests in the world and is located between Eskidere and Bogazoren villages of the Imranli district of the Sivas province in Turkiye. The crests, which ...
3D data integration for geo-located cave mapping based on unmanned aerial vehicle and terrestrial laser scanner data
(INST GEOLOGY & GEOGRAPHY, 2023)
The Akcakale cave is a significant natural and cultural heritage site in the Black Sea region of eastern Turkey. The complex geometry and difficult-to-access areas of the cave have made the use of traditional mapping methods ...
