Early Cambrian S-type granites in the Sakarya Zone, NE Turkey: A record for transition from subduction to post-collisional extension deduced from U[sbnd]Pb zircon age and Nd[sbnd]Hf isotopes
(Elsevier, 2022)
Cadomian realms have recently received much attention in the Alpine–Mediterranean orogenic belts, with discontinuous outcrops extending from the Alps to the İstanbul Zone, Menderes Massif, Taurides in Turkey and Iran as ...
Sedimentological and geochemical approaches for determination of the palaeoceanographic and palaeoclimatic conditions of Lower Cretaceous marine deposits in the eastern part of Sakarya Zone, NE Turkey
(Springer, 2022)
Upper Jurassic–Lower Cretaceous carbonate successions are widely exposed throughout the Sakarya Zone, Northern Turkey. The carbonates are considered as invaluable archives of palaeoceanographic and palaeoclimatic conditions ...
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 ...
Latest Cretaceous "A(2)-type" granites in the Sakarya Zone, NE Turkey: Partial melting of mafic lower crust in response to roll-back of Neo-Tethyan oceanic lithosphere
(Elsevier Science Bv, 2018)
An integrated study of comprehensive geochronological, geochemical, and Sr-Nd-Hf isotopic data was undertaken for the A-type Topcam pluton that intruded within the Sakarya Zone (NE Turkey) with the aims of elucidating its ...
The bio-lithoclastic carbonate facies analysis: Sahinkaya Member Maastrichtian (Late Cretaceous) skeletal carbonate deposit, Sakarya Zone, NE Turkey
(Springer, 2019)
The eastern Sakarya Zone is consensually known as a back-arc setting during the Late Cretaceous period. the region has records, which are in accordance with the environments unstable and carbonate sedimentation formed into ...
Adakite-like parental melt generation by partial fusion of juvenile lower crust, Sakarya Zone, NE Turkey: A far-field response to break-off of the southern Neotethyan oceanic lithosphere
(Elsevier Science Bv, 2019)
The timing of major tectonic events and the driving mechanisms for magma generation during Late Cenozoic convergence and collision between Arabia and Eurasia still remain unknown. the Sakarya Zone (SZ) in northern Turkey ...
Vulnerable geosites of cayirbagi-calkoy (Duzkoy-Trabzon) in the Eastern Black Sea region of NE Turkey and their geotourism potential
(Springer Heidelberg, 2019)
Geotourism is a relatively new branch of tourism dealing with geosites, which are special places that exhibit aspects that characterize the complex history of the Earth. This contribution aims to report an inventory of ...
