Diverse upper Ladinian to middle Carnian radiolarian faunas have been obtained from different ribbon cherts blocks and tectonic slices of the Izmir-Ankara Suture Complex and the marginal sediments of the Tauride-Anatolide platform within the Bornova Flysch Zone, western Turkey.

First evidence of Late Carnian radiolarians from the Izmir-Ankara suture complex, central Sakarya, Turkey: implications for the opening age of the Izmir-Ankara branch of Neo-Tethys
Tekin, UK; Göncüoğlu, Mehmet Cemal; Turhan, N (2002-01-01)
Within the Late Cretaceous melange complex of the Izmir-Ankara suture zone in central Sakarya area, north-western Turkey, a megablock with radiolarian cherts associated with basaltic pillow lavas has been dated by radiolarians. The studied radiolarian assemblage and conodonts yielded an early Late Carnian age. This age is the oldest obtained from the chert blocks all along the suture belt and has important implications for the rifting/opening age of the Izmir-Ankara branch of the Tethys ocean in north-weste...
Structure and geochemistry of an Alaskan-type ultramafic-mafic complex in the Eastern Pontides, NE Turkey

The Karayasmak ultramafic-mafic association (KUMA) in NE Turkey represents an Alaskan-type, pre-Liassic intrusion in the Pulur metamorphic massif and is one of many such intrusive complexes that were emplaced into the continental basement of the Eastern Pontides belt during the pre-Liassic. Its main lithological units include plagioclase peridotite, melagabbronorite, banded gabbro and anorthosite (Phase-I), gabbro-pegmatite dikes (Phase-II), unmetamorphosed banded gabbro (Phase-III), cumulate olivine gabbro...
DISCOVERY OF THE LOWER MURGABIAN (MIDDLE PERMIAN) BASED ON NEOSCHWAGERINIDS AND VERBEEKINIDS IN THE TAURIDES, SOUTHERN TURKEY
Kobayashi, Fumio; Altıner, Demir (2011-04-01)
Lower Murgabian (Roadian) beds have been discovered for the first time in a thick carbonate sequence ranging from Devonian to Triassic in the Hadim area, central Taurides, southern Turkey. The Roadian limestone consists of black algal fusuline packstone and black bioclastic packstone, and contains Presumatrina ciryi n. sp., an evolved form of the genus, Verbeekina erki n. sp., an earliest species of Verbeekina, Dunbarula protomathieui n. sp., an ancestral form of Dunbarula mathieui, and several smaller fora...
The Jurassic-Early Cretaceous basalt-chert association in the ophiolites of the Ankara Melange, east of Ankara, Turkey: age and geochemistry
Bortolotti, Valerio; Chiari, Marco; Göncüoğlu, Mehmet Cemal; Principi, Gianfranco; Saccani, Emilio; TEKİN, UĞUR KAĞAN; Tassinari, Renzo (2018-02-01)
This study is focused on slide blocks including oceanic lavas associated with pelagic sediments within the eastern part of the Ankara Melange. A detailed petrological characterization of the volcanic rocks and a detailed biochronological investigation of the associated radiolarian cherts in eight sections (east of Ankara) was carried out. The volcanic rocks are largely represented by basalts and minor ferrobasalts and trachytes. They show different geochemical affinities and overlapping ages including: (a) ...
Discovery of Middle Permian volcanism in the Antalya Nappes, southern Turkey: tectonic significance and global meaning
Sahin, Nazif; Altıner, Demir; Ercengiz, M. Bulent (Informa UK Limited, 2012-09-01)
Detailed stratigraphic studies on the Middle-Upper Permian rocks of the Tahtalidag nappe (Antalya Nappes), largely exposed along the Guzelsu Corridor in central Taurides, have revealed the presence of basaltic volcanic rocks intercalated within the shallow-marine fossiliferous carbonate successions. Vitrophyric basaltic extrusions producing distinct pillows in the Kizilbag Formation severely dolomitized the associated carbonate rocks. The coeval Cukurkoy Formation, devoid of volcanic layers, is also exposed...
