Petrogenesis of the post-collisional volcanic rocks from the Borcka (Artvin) area: Implications for the evolution of the Eocene magmatism in the Eastern Pontides (NE Turkey)
(Elsevier Science Bv, 2013)
Whole-rock geochemistry, Ar-40-Ar-39 data, and Sr-Nd isotopes are presented for the Eocene Borcka volcanic rocks on the eastern corner of the eastern Pontide orogenic belt (NE Turkey). Borcka (Artvin) volcanic rocks are ...
Adakite-like granitoid porphyries in the Eastern Pontides, NE Turkey: Potential parental melts and geodynamic implications
(Elsevier Science Bv, 2011)
The tectonic setting of the Eastern Pontides during the late Mesozoic to early Cenozoic remains a subject of debate. Petrogenesis of adakite-like granitoid porphyries plays a critical role in determining the nature of the ...
Assessment of Sessile Oak (Quercus petraea L.) Leaf as Bioindicator for Exploration Geochemistry
(Polish Acad Sciences Inst Physics, 2016)
The element contents of sessile oak (Quercus petraea L.) leaves which grow on hydrothermally altered area with high element contents were studied at Gmshane and its near vicinity. The aim of this study is to determine ...
Generation of the Early Cenozoic adakitic volcanism by partial melting of mafic lower crust, Eastern Turkey: Implications for crustal thickening to delamination
(Elsevier, 2010)
Early Cenozoic (48-50 Ma) adakitic volcanic rocks from the Eastern Pontides NE Turkey consist of calc-alkaline and high-K calc-alkaline andesite and dacite, with SiO2 contents ranging from 56 01 to 65 44 wt.%.. This is the ...
