Extensive volcanic activities were developed in Central Anatolia, due to dynamic nature o f the tectonic regime. Although the most of the volcanic zones are represented by major Stratovolcanoes, severe basaltic magmatism with lack of the central cones, were generated over all the Central Anatolia. In this study, we focus on Sivas mafic product s to shed more light on the mantle components, beneath the central Anatolia , that were not investigated in depth so far. Sivas mafic lavas are the most primitive basaltic products along CAFZ zone (MgO 14 wt%) having OIB - like multi - element signatures. Sr - Nd isotopic study reveals that basaltic lavas close and fall within range of OIB field and indicating the involvement of the common component that was not identified in previous studies. 3 Pb isotopic space ( 206 Pb/ 204 Pb, 207 Pb/ 204 Pb, 208 Pb/ 20 Pb) displa y that Sivas mafic lavas fall in the common mantle (C - mantle, Hanan and Graham, 1996) zone and Indian Ocean Ocean MORB sources. Furthermore, Nd - Hf and Pb isotopic data imply that samples do not fall on the mantle array are enriched in Ba, Th, U and deplete d in K and Rb content, proposing that either the minor amount of sediment contributions or metasoma tic processes. Finally, of all the isotopic data and incompatible element signatures indicate that Sivas mafic materials were possibly derived from the inter action of shallow depleted asthenosphere, the regionally heterogeneous lithosphere, and a common source with the isotopic characteristics of the C component.

Petrogenesis of the Neogene-Quaternary mafic lavas from the Tunceli-Elazığ region (Eastern Turkey)
Aktağ, Alican; Sayıt, Kaan; Department of Geological Engineering (2022-1-27)
The most primitive members of the Late Miocene Tunceli and Pleistocene Elazığ mafic volcanics within the Eastern Anatolian Volcanic Province (EAVP) preserve details regarding the chemical geodynamics of eastern Anatolia. This study, therefore, primarily aims to establish the chemical composition of the source components that have contributed to these volcanics to enhance the understanding of the nature of mantle domains beneath eastern Anatolia. Quantitative modelings suggest that at least three distinct c...
Geochemical constraints on the Cenozoic, OIB-type alkaline volcanic rocks of NW Turkey: Implications for mantle sources and melting processes
ALDANMAZ, ERCAN; KÖPRÜBAŞI, NEZİHİ; GÜRER, ÖMER FEYZİ; Kaymakcı, Nuretdin; Gourgaud, Alan (Elsevier BV, 2006-01-01)
The volcanic province of North-West Turkey contains a number of intra-continental alkaline volcanic eruption sequences formed along the localized extensional basins developed in relation with the Late Cenozoic extensional processes. The volcanic suite comprises the extracted melt products of adiabatic decompression melting of the mantle that are represented by small-volume intra-continental plate volcanic rocks of alkaline olivine basalts and basanites with compositions representative of mantle-derived, pri...

The closely related assemblage of igneous and metamorphic rocks that lie within a triangular area approximately bounded by the Tuzgolu Fault, the Ecemis Fault and the Izmir-Ankara-Erzincan Suture and between the lines connecting Ankara, Sivas and Nigde is called the Central Anatolian Crystalline Complex (CACC). The granitoids cropping out within the CACC can be divided areally into three groups: (1) a large number of individual small plutons which form an arcuate set and curve from NE-SW to NW-SE and extend...
Paleotemperature analysis of Aliaga (Izmir, Turkey) geothermal field
Senguler, I; Sener, M; Kök, Mustafa Verşan (2000-05-01)
Mineralogical and organopetrographic analysis were carried out on core samples of four geothermal wells from the Aliaga geothermal field located in western Turkey. Whole rock mineralogy and clay minerals were determined, and thermal maturity of the different levels of the formation was defined by means of vitrinite reflectance measurements. The measured maturity gradients compiled from analytical data for four wells and outcrops ranged from low to very high values.
Paleomagnetic evidence for upper plate response to a STEP fault, SW Anatolia
Kaymakcı, Nuretdin; ÖZKAPTAN, MURAT; Özacar, Atilla Arda; UZEL, BORA; SÖZBİLİR, HASAN (Elsevier BV, 2018-09-15)
Pliny-Strabo Trench is a Subduction Transform-Edge Propagator (STEP) Fault developed on the northern edge of the subducted African Oceanic Lithosphere. It connects the Aegean and Cyprian trenches in the Eastern Mediterranean convergent system. Although, deep geometry of the STEP fault and associated slab tear in mantle are imaged, its shallow vertical and lateral continuation in the crust and impact on the over-riding plate are still unknown. Thus, we have studied SW Anatolia, the candidate site where this ...
