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 ...
Geochemical composition of magnetite from different iron skarn mineralizations in NE Turkey: implication for source of ore-forming fluids
(Springer Heidelberg, 2020)
Iron oxide mineralizations in the eastern part of the Pontides (NE Turkey) are hosted in the skarn environments which are the Pontide paleomagmatic arc. These mineralizations always occur in the contacts between granitoid ...
Geochronological evidence and tectonic significance of Carboniferous magmatism in the southwest Trabzon area, eastern Pontides, Turkey
(Taylor & Francis Inc, 2012)
The northern and southern zones of the eastern Pontides (northeast Turkey) contain numerous plutons of varying ages and compositions. Geochemical and isotopic results on two Hercynian granitoid bodies located in the northern ...
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 ...
The Sr, Nd, Pb and Hf isotopes and crystallization conditions of the middle Eocene Dadibi Pluton in the eastern Sakarya Zone, Turkey
(Cambridge University Press, 2023)
Magmatic activity in the Sakarya Zone, an important segment of the Alpine orogenic belt, continues intermittently from the middle Carboniferous to Miocene. In this study, we provide geochronological and geochemical data ...
