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 ...
Mineralogical and Chemical Characteristics of Clay Areas, Gumushane Region (NE Turkey), and Their Detection Using the Crosta Technique with Landsat 7 and 8 Images
(Springer, 2021)
The clay areas in Gumushane (NE Turkey) were examined in mineralogical and geochemical terms, and by remote sensing methods. X-ray diffraction, scanning electron microscope and chemical analysis were completed on samples ...
Evaluation of potentially toxic element contents and Pb isotopic compositions in Ankara Stream sediments within an urban catchment in central Turkey
(Springer, 2017)
This study aimed to interpret the spatial distribution, enrichment factor (EF), and geo-accumulation of potentially toxic elements in the bed sediments (ASBS) and Pleistocene-aged overbank sediments (ASOS) of the Ankara ...
Nature of tourmaline formation in quartz porphyry in the E Sakarya zone (NE Turkey): geochemistry and isotopic approach
(Edizioni Nuova Cultura, 2019)
Tourmaline, which exhibits important differences in terms of texture and composition, is found in 44 My aged quartz porphyry from Karadag in the eastern Pontide (NE Turkey). Tourmaline has high Al and Mg contents and is ...
Mineralogy and geochemistry of dacitic rocks accompanying the Murgul (Artvin, NE Turkey) massive sulfide deposit
(Pergamon-Elsevier Science Ltd, 2009)
[Abstract Not Available]
Formation of the Egrikar (Gumushane) Fe-Cu skarn type mineralization in NE Turkey: U-Pb zircon age, lithogeochemistry, mineral chemistry, fluid inclusion, and O-H-C-S isotopic compositions
(Elsevier Science Bv, 2017)
The Egrikar Fe-Cu skarn type mineralization is located approximately 100 km NW of Gumuhane in NE Turkey. Geochemical analyses of diorite, which is thought to cause skarn, indicate medium K calc-alkaline (1.3 to similar to ...
