The arkosic sandstones with olistostromes within the "Karakaya Complex" in NW Anatolia to the south of Geyve include a thin layer of green chert with radiolaria. Based on the composition of Albaillellids, the radiolarian assemblage corresponds to the Neoalbaillella ornithoformis assemblage, and its age is assigned to the Changxingian (Late Permian). This is the first finding of synsedimentary radiolarian cherts within the Karakaya units and the indication of latest Permian rifting of the Karakaya basin within the Midian carbonate platform and its pre-Permian basement in the Sakarya Composite Terrane.

Early-Middle Triassic echinoderm remains from the Istranca Massif, Turkey Hagdorn, Hans; Göncüoğlu, Mehmet Cemal (2007-01-01) In the northwestern part of the Istranca Massif close to the Turkish-Bulgarian border, recrystallized limestones above germanotype fluvial clastics (Buntsandstein-equivalents) yielded remains of echinoderms and bivalves. The limestones are lensoidal, flaser-bedded and bioturbated, like the Holocrinus lagerstatten, which are common in the germanotype Muschelkalk. The sufficiently preserved crinoid ossicles can be assigned to genus Holocrinus, a crinoid clade that occurs worldwide in Early and Middle Triassic...
Early Cambrian back-arc volcanism in the western Taurides, Turkey: implications for rifting along the northern Gondwanan margin Gursu, S; Göncüoğlu, Mehmet Cemal (2005-09-01) The Lower Cambrian (Tommotian) Gogebakan Formation in western Central Anatolia is made up of slightly metamorphosed continental to shallow marine elastic rocks with pillowed and massive spilitic lavas and dolerite dykes. Spilitic lavas, commonly amygdaloidal, are albite-and pyroxene-phyric with the metamorphic mineral paragenesis albite + calcite + sericite +/- epidote +/- tremolite +/- chlorite. Dolerite dykes mainly include plagioclase and pyroxene as primary minerals and tremolite epidote chlorite as low...
Middle Carnian Arc-Type Basalts from the Lycian Nappes, Southwestern Anatolia: Early Late Triassic Subduction in the Northern Branch of Neotethys Sayıt, Kaan; Göncüoğlu, Mehmet Cemal (2015-11-01) The Turunc Unit, which represents one of the tectonic slices within the Lycian Nappes in southwestern Anatolia, preserves the remnants derived from the northern branch of Neotethys. The unit includes basalts intercalated with pelagic limestones of middle Carnian age (early Late Triassic) based on the characteristic radiolarian assemblage of the Tetraporobrachia haeckeli Zone. The Turunc lavas reflect trace element signatures resembling those from subduction zones, displaying selective enrichment of Th and l...
LATE CRETACEOUS ARC AND BACK-ARC FORMATION WITHIN THE SOUTHERN NEOTETHYS: WHOLE-ROCK, TRACE ELEMENT AND Sr-Nd-Pb ISOTOPIC DATA FROM BASALTIC ROCKS OF THE YUKSEKOVA COMPLEX (MALATYA- ELAZIG, SE TURKEY) Ural, Melek; ARSLAN, MEHMET; Göncüoğlu, Mehmet Cemal; TEKİN, UĞUR KAĞAN; KÜRÜM, SEVCAN (2015-06-01) The remnants of the Southern Neotethys are represented by ophiolitic bodies and subduction/accretion complexes along the Southeast Anatolian-Zagros suture belt in the Eastern Mediterranean. Around Malatya and Elazig areas (SE Turkey), they are found within imbricated slices of a melange complex, known as the Yuksekova Complex. The studied basaltic rocks are common members of this melange complex, and show distinctive features of sources with tholeiitic to tholeiitic-transitional character. Petrography, whol...
Late Cretaceous Arc Magmatism in the Southern Central Pontides: Constraints for the closure of the Northern Neotethyan branches Sayıt, Kaan; Cemal Göncüoğlu, M.; Ellero, Alessandro; Ottria, Giuseppe; Frassi, Chiara; Marroni, Michele; Pandolfi, Luca (2022-01-31) In the southern Central Pontides in northern Turkey the remnants of two Neotethyan oceanic basins, currently represented by the Intra-Pontide and the Izmir-Ankara-Erzincan sutures, and the interposing continental microplate (i.e., the Sakarya Composite Terrane) are completely dissected by the North Anatolian Shear Zone (NASZ). Within the resulting kilometre-scale, strike-slip fault-bounded blocks, several Late Cretaceous arc-type magmatic units have been detected. In this paper, we present new geochemical d...
