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 ...
A Jurassic volcanic passive margin in Iran and Turkey
(Wiley, 2022)
Broadly similar Early to Middle Jurassic stratigraphic sequences including bimodal igneous rocks of the Sanandaj–Sirjan Zone of Iran and the Sakarya Zone of Turkey suggest that these formed in a common tectonic setting in ...
Post-variscan autochthonous cover in the eastern Sakarya zone, Turkey: evolution of the late carboniferous back-arc ocean to the triassic Karakaya Ocean
(Elsevier, 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 ...
Two-stage bimodal volcanism in a Late Cretaceous arc/back-arc setting, NE Turkey: Constraints from volcano-stratigraphy, zircon Usingle bondPb and 40Ar/39Ar geochronology and whole-rock elemental and Sr-Nd-Pb isotope geochemistry
(Elsevier, 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 ...
The petrogenesis of analcime in the coppermine formation on Robert Island, South Shetland ıslands, Antarctica
(TUBİTAK Scientific & Technical Research Council Turkey, 2023)
The South Shetland Islands were shaped by island arc volcanism that occurred from the Jurassic to the Quaternary. Robert Island is located in the center of this archipelago, and Coppermine Peninsula, located on the ...
Geochemistry of the massive dolomites in Eastern Black Sea region: REE implications for dolomite petrogenesis
(Springer Link, 2023)
Dolomitization is an important diagenetic process observed in carbonate rocks ranging in age from Precambrian to Holocene. The formation of massive dolostone bodies has long been a challenge due to complex sedimentary and ...
Geochemistry of the Lake Sediments on Robert Island, South Shetland Islands, Antarctica: implications for weathering processes in Polar areas
(TUBİTAK Scientific & Technical Research Council Turkey, 2023)
The preliminary results of geochemical analyses of the surface sediments from 4 lakes on Robert Island, South Shetland, Antarctica, are presented herein. The samples were collected during the Turkish Antarctic Expedition ...
Deciphering the shoshonitic monzonites with I-type characteristic, the Sisdaĝi pluton, NE Turkey: Magmatic response to continental lithospheric thinning
(Elsevier, 2012)
Large-scale late Mesozoic to early Cenozoic plutons in the Eastern Pontide orogenic belt mostly show calc-alkaline and I-type geochemical features. However, we identify the Sisda?i pluton that has shoshonitic affinity and ...
Age constraints on intra-formational unconformities in Upper Jurassic-Lower Cretaceous carbonates in northeast Turkey; geodynamic and hydrocarbon implications
(Elsevier Ltd, 2018)
Upper Jurassic-lowermost Cretaceous carbonate build-ups are imaged on seismic data in the Black Sea. They form important, untested, hydrocarbon reservoirs that are the focus of active exploration. Outcrop analogues to these ...
Large Fe-Mn oncoids from Early Jurassic Ammonitico Rosso Facies (eastern Sakarya Zone, NE Turkey): new insight into palaeogeographic conditions of Tethys Ocean
(Taylor & Francis Ltd., 2024)
Oncoids, significant sedimentary structures within the Jurassic strata of the Mediterranean Region,serve as valuable indicators of paleoenvironmental conditions during their formation. One of theimportant examples of oncoids ...
