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 ... -
Postcollisional transition from subduction- to intraplatetype magmatism in the eastern Sakarya zone, Turkey: Indicators of northern Neotethyan slab breakoff
(Geological Soc Amer, Inc, 2019)Postcollisional magmatism in the eastern Sakarya zone was recorded by voluminous basic volcanism and repeated plutonism during the early Cenozoic. the temporal and geochemical evolution of these magmatic rocks is important ... -
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 ... -
Fluid inclusion and stable isotope constraints (C, O, H) on the Dagbasi Fe-Cu-Zn skarn mineralization (Trabzon, NE Turkey)
(Elsevier, 2020)The Dagbasi Fe-Cu-Zn skarn mineralization developed along the contact between the block and lens shaped limestones of the Lower Cretaceous Berdiga Formation and the Upper Cretaceous Dagbasi Granitoid. the exoskam-type ... -
Reply to the discussion by Granier of Vincent et al., (2018) (Marine and Petroleum Geology, 91, 639-657)
(Elsevier Sci Ltd, 2020)Granier (2019) questioned the identification of a number of foraminifer species within the study of Vincent et al. (2018). We dispute his findings and provide supporting evidence for our original identifications. Our ... -
Prediction of parameters which affect beach nourishment performance using MARS, TLBO, and conventional regression techniques
(Springer International Publishing Ag, 2020)Artificial beach nourishment is one of the most important environmentally friendly coastal protection methods since it protects the aesthetic and recreational values of the beach and increases its protective properties. ... -
Analysis of ionospheric TEC anomalies for global earthquakes during 2000-2019 with respect to earthquake magnitude (Mw >= 6.0)
(Pergamon-Elsevier Science Ltd, 2020)In this work, a relationship between ionospheric TEC anomalies and different earthquake magnitude groups before the main shocks was investigated. For this purpose, 2942 global earthquakes with Mw >= 6 from 2000 to 2019 and ... -
Temporal, geochemical and geodynamic evolution of the Late Cretaceous subduction zone volcanism in the eastern Sakarya Zone, NE Turkey: Implications for mantle-crust interaction in an arc setting
(Pergamon-Elsevier Science Ltd, 2020)The Late Cretaceous Artvin volcanic rocks (LCAVs) from the eastern Sakarya zone (ESZ) of NE Turkey are composed of mafic/basaltic (S1-catak and S2-caglayan) and felsic/acidic (S1-Kizilkaya and S2-Tirebolu) rock types that ... -
Sediment-derived melt-related metasomatized mantle wedge as a source of post-subduction Quaternary adakitic porphyries associated with absarokite-shoshonite from the Karadag stratovolcano (Karaman, Central Anatolia, Turkey)
(Pergamon-Elsevier Science Ltd, 2020)The Karadag stratovolcano (KS), located at the southern end of the Cappadocian Volcanic Province in Central Anatolia, Turkey, is a key volcanic vent for understanding the spatiotemporal association between adakitic and ... -
REE characteristics of lower cretaceous limestone succession in Gumushane, NE Turkey: implications for ocean paleoredox conditions and diagenetic alteration
(Mdpi, 2020)Trace and rare earth elements (REEs) are considered to be reliable indicators of chemical processes for the evolution of carbonate systems. One of the best examples of ancient carbonate successions (Berdiga Formation) is ... -
The Paleogene ophiolite conundrum of the Iran-Iraq border region
(Geological Soc Publ House, 2020)New and compiled geochemical, isotopic and geochronological data allow us to propose a new explanation for Paleogene oceanic magmatic rocks along the Iran-Iraq border. These rocks are represented by a thick pile (>1000 m) ... -
Tracking the timing of Neotethyan oceanic slab break-off: Geochronology and geochemistry of the quartz diorite porphyries, NE Turkey
(Pergamon-Elsevier Science Ltd, 2020)The initiation of the break-off of the northern branch of the Neotethyan oceanic lithosphere is an important but poorly understood event in the geology of the Sakarya Zone (SZ) in northeastern Turkey. Although it is wellknown ... -
Silurian to Early Devonian arc magmatism in the western Sakarya Zone (NW Turkey), with inference to the closure of the Rheic Ocean
(Elsevier, 2020)The Rheic Ocean is the most significant Paleozoic ocean that detached peri-Gondwana terranes from the northern Gondwana margin throughout the closure of the Iapetus Ocean. the suture of the Rheic Ocean spreads from Mexico ... -
Melting of the juvenile lower crust in a far-field response to roll-back of the southern Neotethyan oceanic lithosphere: the Oligocene adakitic dacites, NE Turkey
(Elsevier, 2020)Late Cenozoic tectono-thermal events and associated magmatism in the Sakarya Zone (SZ) are still contested. Although documented in the western part of the SZ, thus far, no magmatic activity has been identified in the eastern ... -
Tracking the birth and growth of Cimmeria: Geochronology and origins of intrusive rocks from NW Iran
(Elsevier, 2020)New geochronological and geochemical data for Late Neoproterozoic to Mesozoic intrusive rocks from NW Iran define major regional magmatic episodes and track the birth and growth of one of the Cimmerian microcontinents: the ... -
Slope stability evaluation and monitoring of a landslide: a case study from NE Turkey
(Science Press, 2020)Landslides are quite common natural hazards in the eastern Black Sea region of NE Turkey. Following the heavy rainfall in the Koprulu (Rize) village settlement area, located in this region where the slope debris overlies ... -
