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 ...
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 ...
Petrographical, geochemical and petrological characteristics of Eocene volcanic rocks in the Mescitli area, Eastern Pontides (NE Turkey)
(2016-12)
Mineralogical, petrographical and geochemical data are presented for the Eocene aged Mescitli volcanics in the Eastern Pontides (NE Turkey). The studied rocks are composed of basaltic andesitic, andesitic, ...
Trace and Rare Earth Elements as Indicators of Provenance and Depositional Environments of Lias Cherts in Gumushane, NE, Turkey
(Chemie der Erde,, 2012)
Trace elements and rare earth elements (REEs) of Lias-aged cherts in the Gumushane area were studied in order to understand their origin and depositional environment. Twenty three chert samples from five stratigraphic ...
U-Pb geochronology, bulk-rock geochemistry and petrology of Late Cretaceous syenitic plutons in the Gölköy (Ordu) area (NE Turkey): Implications for magma generation in a continental arc extension triggered by slab roll-back
(2019-01)
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 Yeniköy Tepe plutons in the Ordu ...
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, ...
