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 ...
Petrogenesis and U-Pb zircon chronology of adakitic porphyries within the Kop ultramafic massif (Eastern Pontides Orogenic Belt, NE Turkey)
(Elsevier, 2013)
High-silica adakites intrude the Kop ultramafic massif in the eastern Pontide orogenic belt of NE Turkey. These dominantly dacitic to rhyodacitic plagioclase porphyries form clusters of small intrusions. U-Pb dating of ...
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 ...
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 ...
A review for genesis of continental arc magmas: U, Th, K and radiogenic heat production data from the Gumushane Pluton in the Eastern Pontides (NE Turkiye)
(Elsevier, 2015)
In this study, in situ radioelemental (U-238, Th-232 and K-40) measurements and heat production rate evaluation have been conducted at 132 sites in the Gumushane Pluton of the Eastern Pontides Orogenic Belt (EPOG) of ...
Crustal Contamination of Tertiary Volcanic Rocks: Evidence from K, U, Th and Radiogenic Heat Production Data in Eastern Pontides (NE Turkey)
(Springer Basel Ag, 2021)
Herein, we present new U-238, Th-232, and K-40 radionuclide concentrations, density and radiogenic heat production (RHP) data on the Tertiary volcanic rocks outcropping in Borcka, Gumushane and Trabzon regions within the ...
Geochemical, fluid inclusion and isotopic (O, H and S) constraints on the origin of Pb-Zn +/- Au vein-type mineralizations in the Eastern Pontides Orogenic Belt (NE Turkey)
(Elsevier Science Bv, 2016)
The mineralization area (Altinpinar, Torul-Gumushane) is situated in the Southern Zone of the Eastern Pontides Orogenic Belt (EPOB), which is one of the important metallogenic provinces in the Alpine-Himalayan belt and is ...
The Eastern Black Sea-type volcanogenic massive sulfide deposits: Geochemistry, zircon U-Pb geochronology and an overview of the geodynamics of ore genesis
(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 ...
The in situ natural radionuclide (U-238,Th-232 and(40)K) concentrations in Gumuhane granitoids: implications for radiological hazard levels of Gumuhane city, northeast Turkey
(Springer, 2019)
We have carried out 48 in situ measurements on radioactivities of U-238, Th-232 and K-40 isotopes at the Gumuhane granitoid plutons employing gamma-ray spectrometer with a NaI(Tl) scintillation detector. The radionuclide ...
