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. ...
Concentrations of elements in Lias coals from the eastern Black Sea Region, NE-Turkey
(Taylor & Francis Inc, 2016)
The element contents and organic matter-element relation between Lias-aged coals exposed in four fields in Gumushane and Bayburt were investigated. In general, fixed carbon and gross calorific values of the Edire and ...
Geochemistry of dacitic volcanics in the Eastern Pontides (NE Turkey)
(Maik Nauka/Interperiodica/Springer, 2014)
Dacitic rocks that crop out around the Zigana Mountain (GumuAYhane) in the eastern Pontide (NE Turkey), are mainly composed of quartz, plagioclase, sanidine, amphibole, muscovite, and biotite as the main minerals. Zircon ...
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 ...
Constraints of C-O-S isotope compositions and the origin of the Unlupinar volcanic-hosted epithermal Pb-Zn +/- Au deposit, Gumushane, NE Turkey
(Pergamon-Elsevier Science Ltd, 2016)
The Eastern Pontide Orogenic Belt (EPOB) constitutes one of the best examples of the metallogenic provinces in on the Alpine-Himalayan belt. This study focuses on the genesis of the Unlupinar Pb-Zn +/- Au deposit in the ...
Gamma ray spectrometry for recognition of hydrothermal alteration zones related to a low sulfidation epithermal gold mineralization (eastern Pontides, NE Turkiye)
(Elsevier, 2015)
This study presents an interpretation of radiospectrometric and magnetic data of Arzular mineralization site, which is one of the best examples for epithermal gold deposits located in the southern zone of the Eastern ...
Organic Maturity and Hydrocarbon Potential of Liassic Coals from the Eastern Pontides, NE Turkey
(Taylor & Francis Inc, 2015)
Organic matter content, type of organic material, and thermal maturity of Lias-aged coals of the Gumushane and Bayburt areas were investigated. The total organic carbon contents of coals in the Gumushane area range from ...
Mineralogy and whole rock geochemistry of late Cretaceous sandstones from the eastern Pontides (NE Turkey)
(E Schweizerbartsche Verlags, 2011)
This study focuses on Upper Cretaceous sandstones of the Eastern Pontides to identify the source area, subaerial weathering level, and tectonic environment. Thirty four sandstone samples from six stratigraphic sections ...
Migrating magmatism in a continental arc: Geodynamics of the Eastern Mediterranean revisited
(Pergamon-Elsevier Science Ltd, 2011)
The eastern Pontide orogenic belt in Turkey offers a critical region to evaluate the geodynamic evolution of the eastern Mediterranean region during the late Mesozoic-Cenozoic. Here we synthesize results from our exhaustive ...
The petrogenesis of Early Eocene non-adakitic volcanism in NE Turkey: Constraints on the geodynamic implications
(Elsevier Science Bv, 2014)
Whole-rock geochemistry, mineral chemistry, the Ar-40-Ar-39 age, and Sr-Nd isotopic data are presented for the Early Eocene non-adakitic volcanic rocks on the eastern corner of the Eastern Pontides orogenic belt (NE Turkey). ...
