Subduction-related Late Cretaceous high-K volcanism in the Central Pontides orogenic belt: constraints on geodynamic implications
(Taylor & Francis Ltd, 2016)Mineral chemistry, major and trace elements, Ar-40/Ar-39 age and Sr-Nd-Pb isotopic data are presented for the Late Cretaceous Hamsilos volcanic rocks in the Central Pontides, Turkey. The Hamsilos volcanic rocks mainly ... -
Transition from shoshonitic to adakitic magmatism in the eastern Pontides, NE Turkey: Implications for slab window melting
(Elsevier Science Bv, 2011)The formation of the eastern Pontides orogenic belt has been widely assigned to a northward subduction of the Neotethyan oceanic slab during the late Mesozoic-Cenozoic. Here we provide an alternate model based on new ... -
U-Pb SHRIMP zircon ages, geochemical and Sr-Nd isotopic Compositions of the Late Cretaceous I-type Sarıosman pluton, Eastern Pontides, NE Turkey
(2009)Doğu Pontidler’de Geç Kretase yaşlı Sarıosman plutonu’nun petrojenezi ve U-Pb SHRIMP zirkon yaşları, tüm kayaç Sr-Nd izotop verileri ve arazi, petrografik ve tüm kayaç jeokimyasal verilerine dayanarak irdelenmiştir. I-tipi ... -
U-Pb zircon chronology and petrogenesis of Carboniferous plutons in the northern part of the Eastern Pontides, NE Turkey: Constraints for Paleozoic magmatism and geodynamic evolution
(Elsevier, 2016)Numerous intrusive rocks of varying ages and compositions exist in the Paleozoic to Tertiary periods in the Eastern Pontides. Carboniferous intrusive rocks are commonly observed in the southern part of the Eastern Pontides. ... -
