The Oligocene Ghaleh Yaghmesh plutonic massif (GYPM) consists of diorite, quartz-diorite, tonalite and granodiorite and evolving from metaluminous nature. All the samples are predominantly medium-K calc-alkaline series, having typical characteristics of I-type granitoids. A significant geochemical criteria of the GYPM is the impoverishment of high-field-strength elements (HFSE) (e.i. Zr, Nb, Ti and Hf) and the overabundance of large-ion-lithophile elements (LILE) (e.i. K, Sr, U, Ba and Cs), with respect to the light rare elements (LREE) as compared to chondritic concentration. These geochemical criteria suggest the involvement of sedimentary components in the generation of rocks studied. Furthermore, variable Pb/Ce amounts, linear trend of all rocks studied on Ti/Zr vs. Y1)/Hf diagram, as well as some characteristics petrographic features (e.i. acicular apatite, corroded margin of the plagioclases, the amphiboles and some of the pyroxenes, oscillatory zoning of plagioclases) and the presence of mafic microgranular enclave (MME) indicate that the Ghaleh Yaghmesh parental magma was likely generated by the partial melting of a mixed source dominantly composed of amphibolite and possibly meta-sedimentary source. The overall geochemical and petrographic features are consistent with the interpretation of the Urumieh Dokhtar Magmatic Arc as an active continental margin during subduction of the Neo-Tethyan oceanic crust underneath the Central Iranian microcontinent.

Mineralogic and organic responses to stratigraphic irregularities: an example from the Lower Paleozoic very low-grade metamorphic units of the Eastern Taurus Antochthon, Turkey
Bozkaya, O; Yalcin, H; Göncüoğlu, Mehmet Cemal (2002-01-01)
The paleogeographic and diagenetic-metamorphic evolution of Lower Paleozoic (meta-) sedimentary rocks in the Eastern Taurus Autochthon were studied by means of petrographic and XRD methods. Parameters such as illite crystallinity index, b(0) and % 2M(1) proportion of K-white micas are characterized by an increase in grade from diagenesis at the top to epizone at the bottom. Organic data show a good correlation with phyllosilicate crystal chemical parameters. Three main zones and five sub-zones with distinct...
Tectonics and Magmatism in Turkey and the Surrounding Area
Bozkurt, Erdin; Piper, John D A (Geological Society of London, 2020-01-01)
The volume is divided into five sections: Tethyan evolution, Neotethyan ophiolites, post-Tethyan basin evolution, neotectonics and igneous activity. The first two sections deal with Tethyan oceans, whose growth and subsequent closure dominated the geodynamic framework in the Mesozoic and Cenozoic. The subsequent sections deal with more recent geological developments from the Balkan Peninsula in the west to the Transcaucasus in the east that followed consumption of the Tethyan oceans. There is a broad mix of...
Early Miocene rodents of Gokler (Kazan Basin, Central Anatolia, Turkey)
Joniak, Peter; Pelaez-Campomanes, Pablo; Ostende, Lars W. van den Hoek; Rojay, Fuat Bora (Informa UK Limited, 2019-09-14)
The rich and relatively diverse fossil mammalian assemblage from Gokler is of special importance for understanding of faunal evolution in Central Anatolia. Large mammals were not recovered, but insectivores and rodents are abundant. The assemblage of rodents is studied in detail and comprises mainly diversified cricetids. Dormice are abundant, but are represented by only one species. Squirrels are represented only by few specimens and also beaver remains were identified. Spanocricetodon sinuosus is referred...
Oligocene subduction-related plutonism in the Nodoushan area, Urumieh-Dokhtar magmatic belt: Petrogenetic constraints from U–Pb zircon geochronology and isotope geochemistry
Shahsavari Alavijeh, Badieh; Rashidnejad-Omran, Nematollah; Toksoy Köksal, Fatma; Xu, Wenliang; Ghalamghash, Jalil (Elsevier BV, 2019-3)
Geochemical data and Sr-Nd isotopes of the host rocks and magmatic microgranular enclaves (MMEs) collected from the Oligocene Nodoushan Plutonic Complex (NPC) in the central part of the Urumieh -Dokhtar Magmatic Belt (UDMB) were studied in order to better understand the magmatic and geodynamic evolution of the UDMB. New U-Pb zircon ages reveal that the NPC was assembled incrementally over ca. 5 m.y., during two main episodes at 30.52 +/- 0.11 Ma and 30.06 +/- 0.10 Ma in the early Oligocene (middle Rupelian)...
Archaeogenomic analysis of the first steps of Neolithization in Anatolia and the Aegean
Kilinc, Gulsah Merve; KOPTEKIN, Dilek; Atakuman, Çiğdem; SUMER, Arev Pelin; DONERTAS, Handan Melike; YAKA, Reyhan; Bilgin, Cemal Can; BÜYÜKKARAKAYA, ALİ METİN; Baird, Douglas; ALTINISIK, Ezgi; FLEGONTOV, Pavel; Gotherstrom, Anders; TOGAN, Inci; Somel, Mehmet (2017-11-29)
The Neolithic transition in west Eurasia occurred in two main steps: the gradual development of sedentism and plant cultivation in the Near East and the subsequent spread of Neolithic cultures into the Aegean and across Europe after 7000 cal BCE. Here, we use published ancient genomes to investigate gene flow events in west Eurasia during the Neolithic transition. We confirm that the Early Neolithic central Anatolians in the ninth millennium BCE were probably descendants of local hunter-gatherers, rather th...
