Geochemistry of the post-collisional Miocene mafic Tunceli Volcanics, Eastern Turkey: Implications for the nature of the mantle source and melting systematics Aktağ, Alican; Sayıt, Kaan (2019-01-01) The East Anatolian Accretionary Complex (EAAC) comprises an ideal example of post-collisional volcanism within the Africa-Eurasia collision zone. The Miocene mafic Tuncell Volcanics, as a part of this post-collisional volcanic system, are located in the western termination of EAAC. The mafic Tunceli Volcanics are characterized by mildly alkaline and tholeiitic basalts, in which olivine, clinopyroxene and plagioclase characterize the main mineralogy. The role of fractional crystallization (FC) and assimilati...
Geochemistry of mafic dykes from the Southeast Anatolian ophiolites, Turkey: Implications for an intra-oceanic arc-basin system Colakoglu, Ali Riza; Sayıt, Kaan; Gunay, Kurtulus; Göncüoğlu, Mehmet Cemal (2012-02-01) The Late Cretaceous-Tertiary accretionary prism in Eastern Turkey includes several ophiolitic megablocks and/or tectonic slivers (Mehmetalan, Mollatopuz and Alabayir) within a melange complex, mainly comprising harzburgite, dunite and cumulate-textured gabbro. The diabases, which are the main focus of this study, cut across the ophiolites as parallel and variably thick dyke-swarms. Geochemistry of the diabases reveals three distinct groups, including a) supra-subduction zone (SSZ) type, which is characteriz...
Geochemistry of the metavolcanic rocks from the Cangaldag Complex in the Central Pontides: implications for the Middle Jurassic arc-back-arc system in the Neotethyan Intra-Pontide Ocean Cimen, Okay; Göncüoğlu, Mehmet Cemal; Sayıt, Kaan (2016-01-01) The Cangaldag Complex in northern central Turkey is one of the main tectonic units of the Central Pontide Structural Complex that represents the remains of the poorly known Intra-Pontide branch of the Neotethys. It comprises low-grade metamorphic rocks of intrusive, extrusive, and volcaniclastic origin displaying a wide range of felsic to mafic compositions. Petrographically the complex consists of basalts-andesites-rhyodacites and tuffs with minor amount of gabbros and diabases. On the basis of geochemistr...
GEOCHEMISTRY AND PETROGENESIS OF THE ARC-RELATED KÖSDAĞ METAVOLCANICS, SOUTHERN CENTRAL PONTIDES, NORTHERN TURKEY Berber, Faruk; Sayıt, Kaan; Department of Geological Engineering (2021-12-27) The Kösdağ Metavolcanics (KM) in the southern Central Pontides crops out between the Izmir-Ankara-Erzincan Suture Zone (IAESZ) in the south and the Sakarya Composite Terrane in the north. The unit is represented by a low-grade metamorphic assemblage including meta-basics, meta-intermediates, and meta-felsics, interlayered with recrystallized limestone, mudstone, and chert. While the unit is bounded to the north by the North Anatolian Fault Zone (NAFZ), the Dikmen Formation stratigraphically overlie the unit...
