(Elsevier Science Bv, 2018)This paper presents Sr-Nd-Pb isotopic and whole-rock geochemical data of Miocene to Pliocene volcanic rocks in the Eastern Anatolia (Turkey) aiming to unravel their sources and evolutionary history. The wide compositional ... -
Geochemical characterization of late Jurassic-early Cretaceous age limestones from Gumushane (NE-Turkiye): identification of the source of organic matter and paleo-environment conditions
(SPRINGER, 2022)Samples from late Jurassic-early Cretaceous age limestones in five different areas in the Gumushane region (NE-Turkiye), were studied using TOC/Rock-Eval, and some trace elements analysis, to evaluate their organic material ... -
Geochemical composition of magnetite from different iron skarn mineralizations in NE Turkey: implication for source of ore-forming fluids
(Springer Heidelberg, 2020)Iron oxide mineralizations in the eastern part of the Pontides (NE Turkey) are hosted in the skarn environments which are the Pontide paleomagmatic arc. These mineralizations always occur in the contacts between granitoid ... -
Geochemical constraints on the provenance, mineral sorting and subaerial weathering of Lower Jurassic and Upper Cretaceous clastic rocks of the eastern Pontides, Yusufeli (Artvin), NE Turkey
