Geochemical fingerprints of Late Triassic calc-alkaline lamprophyres from the Eastern Pontides, NE Turkey: A key to understanding lamprophyre formation in a subduction-related environment
Karslı, Orhan; Dokuz, Abdurrahman; Kaliwoda, Melanie; Uysal, İbrahim; Aydın, Faruk; Kandemir, Raif; Fehr, Karl-Thomas (Elsevier Science Bv, 2014)The Eastern Pontides in NE Turkey is one of the major orogenic belts in Anatolia. in this paper, we report our new Ar-40/Ar-39 dating, mineral chemistry, major and trace elements and Sr-Nd-Pb isotopic analyses of the ... -
Geochemical make-up of oceanic peridotites from NW Turkey and the multi-stage melting history of the Tethyan upper mantle
Uysal, İbrahim; Şen, A. Dündar; Ersoy, E. Yalçın; Dilek, Yıldırm; Saka, Samet; Zaccarini, Federica; Escayola, Monica; Karslı, Orhan (Springer Wien, 2014)We present the whole-rock and the mineral chemical data for upper mantle peridotites from the Harmancik region in NW Turkey and discuss their petrogenetic-tectonic origin. These peridotites are part of a Tethyan ophiolite ... -
Geochemical modelling of early Eocene adakitic magmatism in the Eastern Pontides, NE Anatolia: continental crust or subducted oceanic slab origin?
Karslı, Orhan; Uysal, İbrahim; Dilek, Yıldırım; Aydın, Faruk; Kandemir, Raif (Taylor & Francis Inc, 2013)Early Eocene adakitic volcanic and granitoid rocks are widespread in the Eastern Pontides of NE Turkey, providing significant constraints for the early Cenozoic tectonomagmatic evolution of the region. These adakitic rock ... -
Geochemistry, Re-Os isotopes and highly siderophile element abundances in the Eastern Pontide peridotites (NE Turkey): Multiple episodes of melt extraction-depletion, melt-rock interaction and fertilization of the Rheic Ocean mantle
Dokuz, Abdurrahman; Uysal,İbrahim; Dilek, Yıldırım; Karslı, Orhan; Meisel, Thomas; Kandemir, Raif (Elsevier, 2015)We report on the structure, geochemistry, Re-Os isotopes and relative abundances of highly siderophile elements (HSEs) of the Paleozoic peridotite-basalt occurrences in the Eastern Pontide belt of northeastern Turkey. These ... -
Late Jurassic Magmatism and Stratigraphy in the Eastern Sakarya Zone, Turkey: Evidence for the Slab Breakoff of Paleotethyan Oceanic Lithosphere
Dokuz, Abdurrahman; Aydınçakır, Emre; Kandemir, Raif; Karslı, Orhan; Siebel, Wolfgang; Derman, Ahmet Sami; Turan, Mehmet (Univ Chicago Press, 2017)Middle-Late Jurassic Cimmerian events in Turkey have been actively discussed in the past three decades, but proposed tectonic models associated with magmatism, metamorphism, and stratigraphic features remain controversial. ... -
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
Karslı, Orhan; Dokuz, Abdurrahman; Kandemir, Raif (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 ...
