Zircon U[sbnd]Pb geochronology and petrology of the tholeiitic gabbro from the Kovanlık (Giresun) area: Constraints for the Late Cretaceous bimodal arc magmatism in the Eastern Pontides Orogenic Belt, NE Turkey
(Original language, 2022)
Mafic intrusions of the Eastern Pontides Orogenic Belt (EPOB) in NE Turkey are found rarely in varying ages, sizes and compositions. Of these, tholeiitic gabbro stocks, namely Kovanlık gabbro, consist of pyroxene gabbro ...
Eocene tonalite–granodiorite from the Havza (Samsun) area, northern Turkey: Adakite-like melts of lithospheric mantle and crust generated in a post-collisional settin
(2019-01-14)
Eocene intermediate to felsic plutons of different sizes and compositions are widespread in the Eastern Pontides Orogenic Belt in northern Turkey. Of these, the Taşlık Tepe pluton in the Havza (Samsun) area is fine-to-me ...
K-Ar dating, whole-rock and Sr-Nd isotope geochemistry of calc-alkaline volcanic rocks around the Gümüşhane area: implications for post-collisional volcanism in the Eastern Pontides, Northeast Turkey
(Springer-Verlag Wien, 2013-05-14)
Volcanic rocks from the Gümüşhane area in the southern part of the Eastern Pontides (NE Turkey) consist mainly of andesitic lava flows associated with tuffs, and rare basaltic dykes. The K-Ar whole-rock dating of these ...
Mineralogy, whole-rock and Sr–Nd isotope geochemistry of mafic microgranular enclaves in Cretaceous Dagbasi granitoids, Eastern Pontides, NE Turkey: Evidence of magma mixing, mingling and chemical equilibration
(0009-2819/$ - see front matter r 2008 Elsevier GmbH. All rights reserved. doi:10.1016/j.chemer.2008.08.002, 2008-08-04)
Rocks of the Late Cretaceous Dagbasi Pluton (88–83 Ma), located in the eastern Pontides, include mafic microgranular enclaves (MMEs) ranging from a few centimetres to metres in size, and from ellipsoidal to ovoid inshape. ...
Mineral chemistry, crystallization conditions and petrography of Cenozoic volcanic rocks in the Bahçecik (Torul/Gümüşhane) area, Eastern Pontides (NE Turkey).
(2017-12)
Mineralogical, petrographical and mineral chemistry properties are presented for the Cenozoic aged Bahcecik volcanics in the Eastern Pontides (NE Turkey). The studied volcanic rocks are composed of basaltic andesitic, ...
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 ...
