Permian limestones occur widely within the clastic units of the "Karakaya Complex" and are interpreted as allochthonous bodies or olistoliths. In the Kadirler area to the south of Geyve, however, Upper Permian (Midian) quartz sandstones and carbonates with a rich foraminifer fauna disconformably overlie a crystalline basement complex. This basement complex comprises metaclastic rocks, recrystallised limestones, metacherts, and metadiabases, and is intruded by granodiorites. The overlying basal conglomerates and quartzitic sandstones are dominated by pebbles from the basement complex and are followed upward by medium- to thick-bedded dolomites, dolomitic limestones and limestones.

Uppermost Triassic limestone in the Karakaya Complex - Stratigraphic and tectonic significance Okay, AI; Altıner, Demir (2004-05-01) Two important tectonostratigraphic units of the Karakaya Complex in northwest Turkey are: a lower metamorphic sequence of metabasite, phyllite and marble, called the Nilufer Unit; and an upper clastic sequence with Permian and Carboniferous limestone olistoliths called the Hodul Unit. In northwestern Turkey, the Hodul Unit consists of arkosic sandstones, which pass upward into greywacke and siltstone with Permian and Carboniferous limestone blocks. A scarce macrofauna in the sandstones indicates a Norian ag...
Eocene post collisional volcanism in the Central Anatolian Crystalline Complex Turkey Petrology and geodynamic significance Geneli, Fatma; Göncüoğlu, Mehmet Cemal; Lassıter, J; Toksoy Köksal, Fatma (null; 2010-09-04) In the Central Anatolian Crystalline Complex (CACC) the Late Cretaceous postcollisional granitic magmatism is followed by Eocene extension, resulting in formation of roughly E-W trending transtensional basins. The volcanic rocks, mainly submarine lava flows and subareal domes are concentrated along these Middle Eocene (Bartonian) basins. The volcanic rocks are basic to intermediate and are classified as basalt, basaltic andesite and rarely alkali basalt and trachy-andesite. Petrographically they are general...
Petrology of the Eocene volcanism in the central anataolia: implication for the early tertiary evolution of the Central Anatolian crystalline complex Geneli, Fatma; Güncüoğlu, M. Cemal; Kuşcu, Gonca; Department of Geological Engineering (2011) In the Central Anatolian Crystalline Complex (CACC) the Late Cretaceous post-collisional granitic magmatism is followed by Eocene extension, resulting in formation of roughly E-W trending transtensional basins. Formation of these basins was accompanied by calc- alkaline- mildly alkaline volcanism. The volcanic rocks, mainly subaques lava flows and subareal domes are concentrated along these basins and associated with Middle Eocene (Bartonian) Mucur Formation. They are basic to intermediate and are classifie...
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...
Late Permian (Tatarian) fluvio-lacustrine successions in NW Anatolia (Zonguldak Terrane, Turkey): palaeogeographic implications OKUYUCU, CENGİZ; Dimitrova, Tatyana K.; Göncüoğlu, Mehmet Cemal; Gedik, Ibrahim (2017-09-01) Late Permian fluvio-lacustrine successions of the Cakraz Formation in the Zonguldak Terrane between the regions of Akcakoca and Ereli were investigated in order to describe the litho- and biostratigraphic properties and explain the depositional environment. The studied succession with black, dark-grey to greenish-grey shales, siltstones and limestones is named the Alapl Member to distinguish it from the classical red clastic successions, which are tentatively named the Ereli Member of the Cakraz Formation. ...
