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 ... -
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 ... -
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 ... -
K/Ar ages and geochemistry of the post-collisional volcanic rocks in the Ilica (Erzurum) area, eastern Turkey
(E Schweizerbartsche Verlagsbuchhandlung, 2009)The Neogene Ilica volcanics in eastern Anatolia are of sub-alkaline affinity and present features of post-collisional volcanism. The lava flows in the Ilica area reveal K/Ar ages ranging from 13.9 +/- 0.5 to 4.4 +/- 0.3 ... -
