Petrogenesis of post-collisional Middle Eocene volcanism in the Eastern Pontides (NE, Turkey): Insights from geochemistry, whole-rock Sr-Nd-Pb isotopes, zircon U-Pb and 40Ar-39Ar geochronology
(Elsevier GmbH, 2022)
The debate about whether Eocene magmatism is considered to be post-collisional or subduction-related or not still continues. Here we offer new 40Ar-39Ar ad U-Pb zircon geochronology, mineral chemistry, bulk rock and Sr-Nd-Pb ...
Magmatic evolution of the Calc-alkaline Middle Jurassic igneous rocks in the eastern pontides, NE Turkey: insights from geochemistry, whole-rock Sr-Nd-Pb, in situ zircon Lu-Hf isotopes, and U-Pb geochronology
(Taylor and Francis Ltd., 2023)
The Eastern Pontides in NE Turkey hosts a very limited number of plutonic rocks from the Jurassic period. Here we submit new geochemical, Sr-Nd-Pb and zircon Lu-Hf isotope data, and zircon U-Pb ages for plutonic rocks in ...
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. ...
Petrogenesis of the late Cretaceous Turnagöl intrusion in the eastern Pontides: Implications for magma genesis in the arc setting
(Production and hosting by Elsevier, 2012-09-28)
A series of Cretaceous plutons is present in the eastern Pontides of northeastern Turkey. The Turnagöl intrusion is the least studied and, thus, the least understood plutons in the orogen. This intrusion consists of ...
Tersiyer Yaslı Altınpınar Hornblendli Andezitlerinin (Torul-Gümüshane) Petrografisi, Mineral Kimyası ve P-T Kristallesme Kosulları
(Gümüşhane Üniversitesi, 2017-07-14)
Doğu Pontid orojenik kuşağında (KD Türkiye) farklı magma türleri altında oluşmuş farklı volkanik kayaçlar yüzeyleme vermektedir. Tersiyer volkanizması, Gümüşhane ve çevresinde asidik, nötr ve bazik volkanik ve piroklastik ...
Post-Variscan autochthonous cover in the eastern Sakarya Zone, Turkey: Evolution of the late Carboniferous back-arc ocean to the Triassic Karakaya Ocean
(Elsevier Ltd, 2023)
The processes that caused removal of the upper Carboniferous to Permian sediments in the eastern Sakarya Zone, Turkey, are modeled by using of geochemical data and LA-ICP-MS U–Pb ages from detrital zircons. A felsic ...
