Granitic rocks within the Satansarı area are mainly in monzonite and quartz-monzonite compositions with subalkaline, metaluminous and magnesian geochemical characteristics. The Satansarı granitoid show depletion in Ba, Nb, P and Ti and enrichment of Th, U, K and Pb on the primitive mantle-normalized spider diagrams. Moreover, the Satansarı granitoid displays LREE enriched patterns ([La/Yb]N = 18.45 – 21.21) with negative Eu-anomalies, although not very significant ([Eu/Eu*]N = 0.65 – 0.73). Geochemical data infer crustal source with an inherited subduction component and the plagioclase and amphibole fractionation for the Satansarı granitoid. Furthermore, Sr and Nd isotopic data reveal crustal signature for the Satansarı granitoid with high 87Sr/86Sr(T) ratios (0.70826 – 0.70917), and low εNd(T) values (-6.86 – -7.59). Magmatic zircon crystals are typical for the Satansarı granitoid with internal structures representing zircon crystals with inherited cores those are reworked, resorbed and overgrown by igneous zoning and/or completely newly grown zircon crystals in a single magmatic episode. LA-SF-ICP-MS U-Pb zircon ages yield mean 206Pb/238U age of 74.28±0.57 Ma for the Satansarı granitoid with rare discordant analyses giving 207Pb/206Pb ages ranging from the Devonian to the Proterozoic (i.e., 364 Ma to 1263 Ma). LA-MC-ICP-MS data reveal low 176Lu/177Hf ratios and negative εHf(t) values indicating the significance of the crustal signature within the Satansarı zircons. Therefore the potential sources of the Satansarı granitoid are suggested to be crustally-derived melts.

Comparison of zircon/apatite geothermometry methods and zircon typology data of the central anatolian granitoids Köksal, Serhat; Toksoy-köksal, Fatma; Göncüoğlu, M. Cemal (2007-03-24) Zircon typology, proposed by Pupin (1980), is a method based on examination of zircon crystal types in granitic rocks and their statistical evaluation. While providing data for the source of granitoids (e.g., crustal, hybrid, or mantle), zircon typology also suggests the evolution temperatures. In this method, at least 100-150 zircon crystals enriched from a granitoid are examined under the microscope. Crystal faces are determined and zircon crystals are described based on Pupin (1980) classification accord...
Whole-Rock and Nd-Pb isotope geochemistry and radiolarian ages of the volcanics from the Yüksekova Complex (Maden Area, Elazığ, E Turkey): Implications for a Late Cretaceous (Santonian-Campanian) Back-Arc basin in the southern Neotethys Ural, Melek; Sayıt, Kaan; TEKİN, UĞUR KAĞAN (2022-01-31) The Southeast Anatolian Orogenic Belt (SAOB) is characterized by a tectonic assemblage consisting of dismembered ophiolites, subduction-related as-semblages, and continental fragments. Whether the subduction-related volcanic assemblages formed in a Southern Neotethys oceanic arc-basin system (the Yüksekova Complex) or in a back-arc basin (the Maden Complex) originated after the closure of Southern Neotethys is still debated. To shed light on this matter, we focus on the Maden area, known as the type localit...
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)...
Intrusive products of H2O and CO2 rich alkaline melt (Karakoç Magmatic Association): Significance in tethyan realm, Turkey Toksoy Köksal, Fatma (null; 2012-10-01) The Karakoç Magmatic Association (KMA) within the Central Anatolian Crystalline Complex (CACC) consists of ultramafic cumulates, layered gabbros and diorite. The KMA intruded the carbonate dominated upper part of the CACC as a network and includes host rock xenoliths. The KMA is characterized by abundance of Ca-rich phases (green diopside (Mg#=57-93), pargasite (Mg#=41-86), plagioclase (An=91-95), scapolite (Me=42-92), calcite) and Ca-free minerals (phlogopite (Mg#=71-76), alkali-feldspar). The accessories...
