U-Pb geochronology, bulk-rock geochemistry and petrology of Late Cretaceous syenitic plutons in the Golkoy (Ordu) area (NE Turkey): Implications for magma generation in a continental arc extension triggered by slab roll-back
(Pergamon-Elsevier Science Ltd, 2019)
Late Cretaceous felsic plutons in the Eastern Pontides orogenic belt of Turkey are found in varying ages, sizes and compositions. The Late Cretaceous syenitic bodies, namely Direkli and Yenikoy Tepe plutons in the Ordu ...
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 ...
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 ...
Crystal fractionation of adakitic magmas in the crust-mantle transition zone: Petrology, geochemistry and U-Pb zircon chronology of the Seme adakites, eastern Pontides, NE Turkey
(Elsevier Science Bv, 2011)
Plutonic and porphyritic intrusions of adakitic rocks are widely distributed in the southern part of the eastern Pontides orogenic belt in Turkey. Ranging in age from late Paleocene to early Eocene, these intrusions provide ...
Contamination assessment of heavy metals associated with an alteration area: Demiroren Gumushane, NE Turkey
(Springer India, 2015)
Soil samples collected from Demiroren Alteration area, Gumushane NE Turkey were analyzed for heavy metals by using Inductively Coupled Plasma-Atomic Emission Spectrometry and Inductively Coupled Plasma-Mass Spectrometry ...
