A continent-oceanic island arc collision model was proposed as a new geodynamic scenario for the evolution of the Cretaceous Central Anatolian granitoids in the Central Anatolian crystalline complex (CACC) by Boztug et al. (2007b) [Boztug, D., Tichomirowa, M., Bombach, K., 2007b. 207Pb-206Pb single-zircon evaporation ages of some granitoid rocks reveal continent-oceanic island arc collision during the Cretaceous geodynamic evolution of the central Anatolian crust, Turkey. journal of Asian Earth Sciences 31, 71-86]. The key aspects of this model include an intra-oceanic subduction in the Neotethyan Izmir-Ankara Ocean, formation of an island arc and its subsequent collision with the northern margin of the Tauride-Anatolide Platform. The identical scenario was initially proposed by Goncuoglu et al. (1992) [Goncuoglu, M.C., Erler, A., Toprak, V., Yaliniz, K., Olgun, E., Rojay, B., 1992. Geology of the western Central Anatolian Massif, Part II: Central Areas. TPAO Report No: 3155, 76 p]. Moreover, the weighted mean values of the reported 207Pb-206Pb single-zircon evaporation ages by Boztug et al. (2007b) [Boztug, D., Tichomirowa, M., Bombach, K., 2007b. 207Pb-206Pb single-zircon evaporation ages of some granitoid rocks reveal continent-oceanic island arc collision during the Cretaceous geodynamic evolution of the central Anatolian crust: Turkey. journal of Asian Earth Sciences 31, 71-86] from A-type granitoids in the CACC seem to be miscalculated and contrast with the field data.

Middle Jurassic Lower Cretaceous biostratigraphy in the Central Pontides (Turkey): Remarks on paleogeography and tectonic evolution Rojay, Fuat Bora; Altıner, Demir (1998-08-01) The deposition of Jurassic-Lower Cretaceous carbonates in the Pontides was controlled mainly by the evolution of an Atlantic-type continental margin in the Tethys. The study of several stratigraphic sections from allochthonous slices and blocks of the North Anatolian Ophiolitic Melange provided insight into the Middle Jurassic-Early Cretaceous paleogeographic evolution of the Central Pontide Belt. The Callovian-Aptian successions span the Globuligerina gr. oxfordiana, Clypeina jurassica (equivalent of the T...
GEOCHEMICAL CHARACTERISTICS OF GRANITOIDS ALONG THE WESTERN MARGIN OF THE CENTRAL ANATOLIAN CRYSTALLINE COMPLEX AND THEIR TECTONIC IMPLICATIONS AKIMAN, O; ERLER, A; GONCUOGLU, MC; Güleç, Nilgün Türkan; GEVEN, A; TURELI, TK; KADIOGLU, YK (1993-12-01) 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...
An example of an accretionary fore-arc basın from Northern Central Anatolia and its implicaiıons for the history of subduction of neo-tethys in Turkey KOCYIGIT, A (1991-01-01) Deformed sedimentary sequences of Late Cretaceous-middle Eocene age located between the Sakarya continent and the Anatolian Complex have been interpreted as the fill of a forearc basin. The history and structure of this basin are critical for understanding the evolution of the Neo-Tethyan subduction in the Middle East. I test and elaborate upon this interpretation on the basis of three basic outcrop areas of Upper Cretaceous-lower Tertiary sedimentary sequences confined to a northeast-southwest-trending b...
GEOLOGY AND CHEMICAL VARIATIONS IN TOURMALINE FROM THE QUARTZ-TOURMALINE BRECCIAS WITHIN THE KERKENEZ GRANITE-MONZONITE MASSIF, CENTRAL ANATOLIAN CRYSTALLINE COMPLEX, TURKEY Demirel, Serhat; Göncüoğlu, Mehmet Cemal; Topuz, Gueltekin; IŞIK, VEYSEL (2009-08-01) A hydrothermal breccia zone 6 km long and 2 km wide, crossed by quartz-tourmaline veins, occurs to the south of the Late Cretaceous Kerkenez granite-monzonite massif in the northern part of the Central Anatolian Crystalline Complex, Yozgat, Turkey. This breccia zone is characterized by numerous veins, a few millimeters to 1 meter in width, and display typical microtectonic features of multiple brecciation. Trace amounts of albite, K-feldspar, epidote, muscovite and rutile are associated with quartz and tour...
Developments in Ground Motion Predictive Models and Accelerometric Data Archiving in the Broader European Region Akkar, Sinan; Kale, Özkan (SPRINGER, PO BOX 17, 3300 AA DORDRECHT, NETHERLANDS; 2015) This paper summarizes the evolution of major strong-motion databases and ground-motion prediction equations (GMPEs) for shallow active crustal regions (SACRs) in Europe and surrounding regions. It concludes with some case studies to show the sensitivity of hazard results at different seismicity levels and exceedance rates for local (developed from country-specific databases) and global (based on databases of multiple countries) GMPEs of the same region. The case studies are enriched by considering other glo...
