Eocene tonalite-granodiorite from the Havza (Samsun) area, northern Turkey: adakite-like melts of lithospheric mantle and crust generated in a post-collisional setting
(Taylor & Francis Inc, 2020)
Eocene intermediate to felsic plutons of different sizes and compositions are widespread in the Eastern Pontides Orogenic Belt in northern Turkey. Of these, the Taslik Tepe pluton in the Havza (Samsun) area is fine-to-me ...
Mineralogy, chemistry, and genesis of zeolitization in Eocene tuffs from the Bayburt area (NE Turkey): Constraints on alteration processes of acidic pyroclastic deposits
(Pergamon-Elsevier Science Ltd, 2020)
Eocene vitric tuffs in the Bayburt area (NE Turkey) possess a dacite-rhyodacite composition and contain abundant altered glass shards and flattened fibrous pumice with lesser amounts of pyrogenic minerals (plagioclase, ...
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 ...
Geochronology, geochemistry, and petrology of adakitic Pliocene-Quaternary volcanism in the Sebinkarahisar (Giresun) area, NE Turkey
(Taylor & Francis Inc, 2019)
The Pliocene-Quaternary volcanics in NE Turkey are mainly hornblende-phyric trachyandesites having a narrow range of SiO2 from 61.88 to 63.00 wt.% and exhibiting adakitic signatures with their Na2O (3.67-4.27 wt.%), Al2O3 ...
Eocene I-type magmatism in the Eastern Pontides, NE Turkey: insights into magma genesis and magma-tectonic evolution from whole-rock geochemistry, geochronology and isotope systematics
(Taylor & Francis Inc, 2020)
The Eastern Pontides orogenic belt in NE Turkey hosts numerous I-type plutons of Eocene epoch. Here, we report new U-Pb SHRIMP zircon ages and in situ zircon Lu-Hf isotopes along with bulk-rock geochemical and Sr-Nd-Pb-O ...
