Concentrations of elements in Lias coals from the eastern Black Sea Region, NE-Turkey
Eker, Cigdem Saydam; Akpinar, Ibrahim; Sipahi, Ferkan; Yapici, Ejder (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)
Sipahi, Ferkan; Sadiklar, M. Burhan (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 ... -
Geochronological evidence and tectonic significance of Carboniferous magmatism in the southwest Trabzon area, eastern Pontides, Turkey
Kaygusuz, Abdullah; Arslan, Mehmet; Siebel, Wolfgang; Sipahi, Ferkan; Ilbeyli, Nurdane (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 ... -
Organic Maturity and Hydrocarbon Potential of Liassic Coals from the Eastern Pontides, NE Turkey
Eker, C. S.; Sipahi, F.; Akpinar, I. (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 ... -
Petrography, mineral chemistry and crystallization conditions of cenozoic plutonic rocks located to the north of Bayburt (Eastern Pontides, Turkey)
Kaygusuz, Abdullah; Yucel, Cem; Arslan, Mehmet; Sipahi, Ferkan; Temizel, Irfan; Cakmak, Gokhan; Guloglu, Z. Samet (Maden Tetkik Ve Arama Genel Mudurlugu-Mta, 2018)The Eastern Pontides comprise many intrusive bodies varying in composition, size and age from Palaeozoic to Cenozoic. Especially Cenozoic aged bodies are commonly observed in the southern part, while they are rarely exposed ... -
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
Kaygusuz, Abdullah; Arslan, Mehmet; Sipahi, Ferkan; Temizel, Irfan (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. ...
