Mineralogy, chemistry, and genesis of zeolitization in Eocene tuffs from the Bayburt area (NE Turkey): Constraints on alteration processes of acidic pyroclastic deposits
(Pergamon-Elsevier Science Ltd, 2020)Eocene vitric tuffs in the Bayburt area (NE Turkey) possess a dacite-rhyodacite composition and contain abundant altered glass shards and flattened fibrous pumice with lesser amounts of pyrogenic minerals (plagioclase, ... -
One-Dimensional Thermal Modeling of the Eastern Pontides Orogenic Belt (NE Turkey)
(Birkhauser Verlag Ag, 2012)The eastern Pontides orogenic belt is one of the most complex geodynamic settings in the Alpine-Himalayan belt due to the lack of systematical geological and geophysical data. In this study, 1D crustal structure and P-wave ... -
Origin of analcimes in the Tertiary volcanic rocks from the Eastern Pontides (NE Turkey): a textural, mineralogical and geochemical approach
(E Schweizerbartsche Verlagsbuchhandlung, 2014)Silica-undersaturated mafic volcanic rocks of Tertiary age in form of lava flows, dikes and sills of tephritic compositions extend along the northern part of the Eastern Pontides. These rocks typically contain Ca-clinopyroxene ... -
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 ... -
Petrogenesis of the post-collisional volcanic rocks from the Borcka (Artvin) area: Implications for the evolution of the Eocene magmatism in the Eastern Pontides (NE Turkey)
(Elsevier Science Bv, 2013)Whole-rock geochemistry, Ar-40-Ar-39 data, and Sr-Nd isotopes are presented for the Eocene Borcka volcanic rocks on the eastern corner of the eastern Pontide orogenic belt (NE Turkey). Borcka (Artvin) volcanic rocks are ... -
Petrography and geochemistry of Eocene sandstones from eastern Pontides (NE TURKEY): Implications for source area weathering, provenance and tectonic setting
(Maik Nauka/Interperiodica/Springer, 2012)Subaerial weathering level, source area and tectonic environments were interpreted by using petrographic and geochemical characteristics of Eocene age sandstones found in the eastern Pontides. The thickness of Eocene age ... -
Remote Sensing Technique for Capturing and Exploration of Mineral Deposit Sites in Gumushane Metallogenic Province, NE Turkey
(Springer India, 2017)This study examines the determination and confirmation of mineral deposits in the Gumushane Province,Turkey. Rather than using classical techniques, Remote Sensing (RS) and Geographic Information System GIS technologies ... -
A slab detachment and delamination model for the generation of Carboniferous high-potassium I-type magmatism in the Eastern Pontides, NE Turkey: The Kose composite pluton
(Elsevier Science Bv, 2011)The Hercynian Kose composite pluton (KCP) is located in the Eastern Pontides, Turkey, and consists of two units of high-K calc-alkaline, primarily peraluminous granites: (i) the internal body, and (ii) the external body. ... -
Structure and geochemistry of an Alaskan-type ultramafic-mafic complex in the Eastern Pontides, NE Turkey
(Elsevier, 2010)The Karayasmak ultramafic-mafic association (KUMA) in NE Turkey represents an Alaskan-type, pre-Liassic intrusion in the Pulur metamorphic massif and is one of many such intrusive complexes that were emplaced into the ... -
Subduction-related Late Carboniferous to Early Permian Magmatism in the Eastern Pontides, the Camlik and Casurluk plutons: Insights from geochemistry, whole-rock Sr-Nd and in situ zircon Lu-Hf isotopes, and U-Pb geochronology
(Elsevier, 2016)Late Carboniferous to early Permian granitoid rocks represent a volumetrically minor component of the Eastern Pontide lithosphere, but they preserve useful information about the region's tectonomagmatic history. The Casurluk ... -
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 ... -
Three-directional extensional deformation and formation of the Liassic rift basins in the Eastern Pontides (NE Turkey)
(Slovak Acad Sciences Geological Inst, 2006)The Eastern Pontide magmatic arc (NE Turkey) was rifted by the polyphase extensional tectonic regimes in the Early Jurassic. While alternated volcanics and siliciclastic sedimentary rocks accumulated during the episodic ... -
Two-and-Three-Dimensional Crustal Thickness of the Eastern Pontides (NE Turkey)
(Scientific Technical Research Council Turkey-Tubitak, 2009)The Eastern Pontide orogenic belt is divided into three subzones ( northern, southern and axial zones) based on present lithologies and facies associations. NE-SW-, NW-SE- and E-W-trending fault systems, which play an ... -
