Alternating radiolarian cherts and mudstones associated with basaltic lavas occur in a olistolith within the Late Cretaceous Bornova Flysch in W Anatolia. Cherts yielded diverse and moderately preserved, Nassellaria-dominated radiolarian faunas of late Bathonian-early Callovian age. Associated volcanic rocks are geochemically classified as remnants of oceanic seamounts. This is so far the first late Middle Jurassic age from the crust of the Neotethyan Izmir-Ankara Ocean in W Anatolia, and suggests that its spreading started earlier. Similar ages were reported from the Vardar and Meliata-Hallstadt Tethyan oceanic branches in Greece and Serbia, which also opened in Late Triassic but closed earlier.

Middle-Late Triassic radiolarian cherts from the Arkotdag m lange in northern Turkey: implications for the life span of the northern Neotethyan branch TEKİN, UĞUR KAĞAN; Göncüoğlu, Mehmet Cemal; Pandolfi, Luca; Marroni, Michele (2012-09-01) Moderately to well-preserved, relatively diverse Middle and Late Triassic radiolarian assemblages have been obtained from the chert slide-blocks within the Late Cretaceous melange of the IntraPontide Suture Zone at the Pelitoren village to the NE of Kastamonu-Arac in northern Central Anatolia. In this locality, chert slide-blocks are tectonically overlain by metamorphic sole of the serpentinized peridotites belonging to the IntraPontide ophiolites. The oldest radiolarian assemblages, with the middle Late An...
Upper Maastrichtian - Eocene Planktonic Foraminiferal Zonation in the Besparmak Range, Northern Cyprus Hakyemez, Aynur; Altıner, Sevinç (2010-01-01) The Lapta Group, Late Cretaceous-Middle Eocene in age, mainly consists of basal breccias, micritic limestones and clayey limestones with volcanic, calciturbidite and breccia interbeds. It unconformably overlies the Triassic-Lower Cretaceous platform carbonates in the Besparmak (Kyrenia) Range. The detailed study of planktonic foraminiferal assemblages obtained from three stratigraphic sections through the Lapta Group revealed six biozones: Racemiguembelina fructicosa Zone and Abathomphalus mayaroensis Zone ...
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...
Upper Cretaceous volcaniclastic complexes and calcareous plankton biostratigraphy in the Western Pontides, NW Turkey Boehm, Katharina; Wagreich, Michael; Wolfgring, Erik; Tuysuz, Okan; Gier, Susanne; Yılmaz, İsmail Ömer (2019-01-01) This study describes and interprets Upper Cretaceous volcaniclastics interbedded with hemipelagic to pelagic limestones, marls, and turbidites from the Western Pontides, northwestern Turkey. The Derekey Formation, the Unaz Formation (red pelagic limestone unit), and the Cambu Formation can be distinguished, overlain by the turbiditic Akveren Formation. Biostratigraphic ages from the predominantly volcaniclastic Derekoy Formation indicate Turonian (Dicarinella concavata planktonic foraminifera zone, CC13/UC8...
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...
