Late Cretaceous Arc Igneous Activity: The Eğrikar Monzogranite Example
(International Geology Review, 2018)
The geochemical and Sr–Nd–Pb isotope properties, as well as the Laser Ablation Inductively Coupled Plasma and Mass Spectrometry (LA-ICP-MS) U–Pb zircon age, of Eğrikar Monzogranite in the eastern Pontides, are primarily ...
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, 2015-11-11)
The mineralization area (Altınpınar, Torul–Gümüşhane) 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, 2013-12-11)
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 ...
Eocene tonalite–granodiorite from the Havza (Samsun) area, northern Turkey: Adakite-like melts of lithospheric mantle and crust generated in a post-collisional settin
(2019-01-14)
Eocene intermediate to felsic plutons of different sizes and compositions are widespread in the Eastern Pontides Orogenic Belt in northern Turkey. Of these, the Taşlık Tepe pluton in the Havza (Samsun) area is fine-to-me ...
Formation of skarns at Gümüşhane (Northeastern Turkey)
(Neues Jahrbuch für Mineralogie-Abhandlungen, 2011)
Skarn deposits are located in the NE Black Sea region of Turkey belonging to the Alpin metallogenic province. The Fe skarn deposit at Arnastal is hosted by Late Cretaceous carbonate rocks comprised of limestone and the ...
The Geochemical and Sr-Nd isotopic Characteristics of Murgul (Artvin) Volcanics in the Eastern Black Sea Region (NE Turkey).
(Chemie der Erde/Geochemistry, 2014)
The studied volcanic rocks are footwall and hanging wall dacites from the Murgul mine and the surrounding area. Moreover, the hanging wall dacites contain enclaves. Footwall dacite contains biotite, whereas hanging wall ...
Geochronology, geochemistry, and petrogenesis of the Eocene Bayburt intrusions, Eastern Pontide, NE Turkey: implications for lithospheric mantle and lower crustal sources in the high-K calc-alkaline magmatism
(2015-04-28)
Eocene I-type plutons are widespread in the Eastern Pontides, Northeastern Turkey. Geochemical and isotopic results on two Eocene intrusive bodies located in the southern zone of the Eastern Pontides were utilized to achieve ...
Geothermal energy for clean and sustainable development in Turkey
(2019-05-05)
Turkey has a limited amount of fossil fuel reserve, thus is dependent on foreign energy. Approximately 75% of current energy consumption is met by imports. However, Turkey has a high potential of renewables such as biomass, ...
The in situ natural radionuclide (238U,232Th and40K) concentrations in Gümüşhane granitoids: implications for radiological hazard levels of Gümüşhane city, northeast Turkey
(Elsevier, 2019-05-12)
We have carried out 48 in situ measurements on radioactivities of 238U, 232Th and 40K isotopes at the Gümüşhane granitoid plutons employing gamma-ray spectrometer with a NaI(Tl) scintillation detector. The radionuclide ...
K-Ar dating, whole-rock and Sr-Nd isotope geochemistry of calc-alkaline volcanic rocks around the Gümüşhane area: implications for post-collisional volcanism in the Eastern Pontides, Northeast Turkey
(Springer-Verlag Wien, 2013-05-14)
Volcanic rocks from the Gümüşhane area in the southern part of the Eastern Pontides (NE Turkey) consist mainly of andesitic lava flows associated with tuffs, and rare basaltic dykes. The K-Ar whole-rock dating of these ...
