Arc magmatism as a window to plate kinematics and subduction polarity: Example from the eastern Pontides belt, NE Turkey
Eyüboğlu, Yener; Santosh, M.; Bektas, Osman; Ayhan, Seda (2011)The Eastern Pontides orogenic belt in the Black Sea region of Turkey offers a critical window to plate kinematics and subduction polarity during the closure of the Paleotethys. Here we provide a brief synthesis on recent ... -
Determination of Tectonic and Crustal Structure of the Eastern Pontide Orogenic Belt (NE Turkey) Using Gravity and Magnetic Data
Maden, Nafiz; Gelisli, Kenan; Eyuboglu, Yener; Bektas, Osman (Springer Basel Ag, 2009)The Eastern Pontide Orogenic Belt is one of the most complex geodynamic settings within the Alpine belt. Subduction polarity, which is responsible for the formation of the Eastern Pontide Magmatic Arc, is still under debate ... -
Different modes of stress transfer in a strike-slip fault zone: an example from the North Anatolian Fault System in Turkey
Bektas, Osman; Eyueboglu, Yener; Maden, Nafiz (Scientific Technical Research Council Turkey-Tubitak, 2007)The dextral North Anatolian Fault System (NAFS) extends for well over 1000 km from the compressive tectonic domain of eastern Anatolia into the broad and diverse tectonic domain of the western Anatolian, Marmara and Aegean ... -
The Eastern Black Sea-type volcanogenic massive sulfide deposits: Geochemistry, zircon U-Pb geochronology and an overview of the geodynamics of ore genesis
Eyuboglu, Yener; Santosh, M.; Yi, Keewook; Tuysuz, Necati; Korkmaz, Sadettin; Akaryali, Enver; Bektas, Osman (Elsevier, 2014)The Meso-Cenozoic geodynamic evolution of the eastern Pontides orogenic belt provides a key to evaluate the volcanogenic massive sulfide (VMS) deposits associated with convergent margin tectonics in a Cordilleran-type ... -
Late Triassic subduction-related ultramafic-mafic magmatism in the Amasya region (eastern Pontides, N. Turkey): Implications for the ophiolite conundrum in Eastern Mediterranean
Eyuboglu, Yener; Santosh, M.; Bektas, Osman; Chung, Sun-Lin (Pergamon-Elsevier Science Ltd, 2011)The eastern Pontides orogenic belt of northeastern Turkey offers critical clues on convergent margin tectonics associated with the late Mesozoic-early Cenozoic geodynamic evolution of the eastern Mediterranean region. Here ... -
Mid-cretaceous olistostromal ophiolitic melange developed in the back-are basin of the eastern Pontide magmatic arc, Northeast Turkey
Eyuboglu, Yener; Bektas, Osman; Pul, Dilek (Taylor & Francis Inc, 2007)Geological and geochemical characteristics of the Mid-Cretaceous olistostromal ophiolitic melange exposed in the southern part of the eastern Pontide magmatic arc indicates that it originally formed during the drifting ... -
Structure and geochemistry of an Alaskan-type ultramafic-mafic complex in the Eastern Pontides, NE Turkey
Eyuboglu, Yener; Dilek, Yildirim; Bozkurt, Erdin; Bektas, Osman; Rojay, Bora; Sen, Cuneyt (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 ... -
Three-directional extensional deformation and formation of the Liassic rift basins in the Eastern Pontides (NE Turkey)
Eyuboglu, Yener; Bektas, Osman; Seren, Aysel; Maden, Nafiz; Ozer, Rahsan; Jacoby, Wolfgang R. (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)
Maden, Nafiz; Gelisli, Kenan; Eyuboglu, Yener; Bektas, Osman (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 ...
