Crust and upper mantle dynamics of Turkey inferred from passive seismology: implications of segmented slab geometry Berk, Biryol; Susan, Beck; George, Zandt; Kaymakcı, Nuretdin (2010-10-08) Turkey lies within the Alpine–Himalayan orogenic belt and is shaped by continent-continent collision in the east, slab rollback and back arc extension in the west and westward extrusion of Anatolian plate in between. In this study, passive seismic data are used to analyze the crust and upper mantle structure of the region to test different tectonic models proposed for Turkey and its surrounding. In Eastern Turkey, continent-continent collision resulted in a topographic high, the East Anatolian Plateau which...
Crustal seismic anisotropy in central Tibet: Implications for deformational style and flow in the crust Özacar, Atilla Arda (2004-12-01) [ 1] Receiver functions obtained at INDEPTH III stations located near the Bangong-Nujiang suture in central Tibet display a weak Moho signal and strong P to S conversions within the first 5 s that vary systematically with back-azimuth. A single station with representative azimuthal variations located at the sharp onset of strong SKS splitting, is modeled for both dipping layers and seismic anisotropy by using a global minimization technique. Inversion results indicate strong anisotropy (> 10%) near the surf...
Crust–mantle interaction in western Turkey: Implications from Sr and Nd isotope geochemistry of Tertiary and Quaternary volcanics Güleç, Nilgün Türkan (Cambridge University Press (CUP), 1991-01-01) The isotopic composition of Sr and Nd together with the abundance data for major and trace elements are reported for Tertiary to Quaternary volcanics from a variety of localities in western Turkey. These data are used to evaluate the role of crust–mantle interaction in the petrogenesis of the western Turkish volcanics. The major and trace element chemistry reveals a general change in the nature of volcanism from dominantly calc-alkaline in Tertiary to alkaline in Quaternary times. The calc-alkaline rocks ar...
Crustal source of the Late Cretaceous Satansari monzonite stock (central Anatolia - Turkey) and its significance for the Alpine geodynamic evolution Köksal, Serhat; Toksoy Köksal, Fatma; Göncüoğlu, Mehmet Cemal (2013-04-01) The Late Cretaceous granitic rocks within central Anatolia (Turkey) not only date and show the magmatic aspects of the Alpine realm, but also give clues about its geodynamic character. Among them, the Satansari monzonite stock (SMS), part of the Terlemez pluton (Aksaray), characterizing the inception of an extensional tectonic regime in central Anatolia, has a subalkaline, metaluminous and magnesian geochemical nature with depletion in Ba, Nb, P and Ti, and with enrichment of Th, U, K and Pb relative to pri...
