Genesis and geodynamic significance of chromitites from the Orhaneli and Harmancik ophiolites (Bursa, NW Turkey) as evidenced by mineralogical and compositional data
Uysal, İbrahim; Akmaz, Recep Melih; Kapsiotis, Argyrios; Demir, Yılmaz; Saka, Samet; Avcı, Erdi; Mueller, Dirk (Elsevier, 2015)Chromitites from Orhaneli and Harmancik ophiolites (Bursa, NW Turkey) are mainly associated with dunites. They occur as banded and lenticular bodies showing massive and disseminated textures and are composed of magnesiochromite ... -
Geochemical make-up of oceanic peridotites from NW Turkey and the multi-stage melting history of the Tethyan upper mantle
Uysal, İbrahim; Şen, A. Dündar; Ersoy, E. Yalçın; Dilek, Yıldırm; Saka, Samet; Zaccarini, Federica; Escayola, Monica; Karslı, Orhan (Springer Wien, 2014)We present the whole-rock and the mineral chemical data for upper mantle peridotites from the Harmancik region in NW Turkey and discuss their petrogenetic-tectonic origin. These peridotites are part of a Tethyan ophiolite ... -
Petrogenesis of ultramafic rocks from the eastern Orhaneli ophiolite, NW Turkey: Hints on the initiation and evolution of melt-peridotite interaction processes within a heterogeneously depleted mantle section
Uysal, İbrahim; Dokuz, Abdurrahman; Kapsiotis, Argyrios; Saka, Samet; Karslı, Orhan; Kaliwoda, Melanie; Mueller, Dirk (Pergamon-Elsevier Science Ltd, 2017)The eastern Orhaneli ophiolite in NW Anatolia (Turkey) consists of voluminous dunite and minor harzburgite intruded by clinopyroxenite veins. Harzburgite contains spinel of low Cr# [100 x Cr/(Cr + Al) = 40-45] and diopside ...
