Zircon Lu-Hf isotope systematics and U-Pb geochronology, whole-rock Sr-Nd isotopes and geochemistry of the early Jurassic Gokcedere pluton, Sakarya Zone-NE Turkey: a magmatic response to roll-back of the Paleo-Tethyan oceanic lithosphere
(Springer, 2017)
The early Mesozoic was a critical era for the geodynamic evolution of the Sakarya Zone as transition from accretion to collision events in the region. However, its complex evolutionary history is still debated. To address ...
Geochemistry, fluid inclusion and stable isotope constraints (C and O) of the Sivrikaya Fe-skarn mineralization (Rize, NE Turkey)
(Elsevier Science Bv, 2017)
The Sivrikaya Fe-skarn mineralization is hosted by dolomitic limestone layers of Late Cretaceous volcano-sedimentary unit, comprised of andesite, basalt and their pyroclastites, including, sandstone, shale and dolomitic ...
Cordierite-bearing strongly peraluminous cebre rhyolite from the eastern Sakarya Zone, NE Turkey: Constraints on the variscan orogeny
(Elsevier, 2017)
The Cebre Rhyolite with an outcropping area up to 12 km(2) is one of the rare extrusions in the Variscan basement of the Sakarya Zone. the unit consists of high-K calc alkaline rhyolites (SiO2 = 74-82 wt.%). Abundant ...
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
(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 ...
Crustal evolution of NW Iran: Cadomian arcs, archean fragments and the cenozoic magmatic flare-up
(Oxford Univ Press, 2017)
The Cadomian orogen of NW Iran includes a series of metamorphic rocks with zircon U-Pb ages between ca 562 and 505 Ma (Ediacaran to middle Cambrian). the Ediacaran-Cambrian basement is intruded by a series of Late Eocene-Late ...
