Early-Middle Triassic echinoderm remains from the Istranca Massif, Turkey

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 sediments. This is so far the first Triassic fossil data from the Istranca Massif and provides evidence for the correlation with similar Triassic successions in the Balkans to the West and the Istanbul Terrane to the East.


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...
Late Cretaceous Volcaniclastics in NW Turkey
Boehm, Katharina; Wolfgring, Eric; Yılmaz, İsmail Ömer; Tüysüz, Okan; Wagreich, Michael (null; 2015-04-17)
On the southwestern coast of the Black Sea, in the western Pontides Upper Cretaceous tuff layers are present. The tuffs are intercalated with limestones, marls and turbidites and were investigated with focus on their geochemistry, to get new insights to the arrangement of terranes and ocean basins at this time. In the region two Upper Cretaceous volcanic units can be distinguished, separated by distinct red pelagic limestone successions, belonging to the Unaz Formation. The lower volcanic unit is named Dere...
Late Middle Jurassic (Late Bathonian-early Callovian) radiolarian cherts from the Neotethyan Bornova flysch zone, Spil Mountains, Western Turkey
TEKİN, UĞUR KAĞAN; Göncüoğlu, Mehmet Cemal (2009-06-01)
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 ...
Late Cretaceous stratigraphy in the Mudurnu-Goynuk Basin (Turkey) and inferences on sea-level change in the Late Campanian to Early Maastrichtian
Wolfgring, Erik; Wagreich, Michael; Yılmaz, İsmail Ömer; Liu Shasha, Liu Shasha; Boehm, Katharina (Geological Society of London, 2020-01-01)
Upper Cretaceous strata at Goynuk, northwestern Anatolia, Turkey, provide a geological record of the Campanian-Maastrichtian from the Sakarya Terrane along the active Neotethys margin. Shales and shaly marls with siliciclastic and volcaniclastic intercalations indicate a pelagic palaeoenvironment rich in planktonic and benthonic foraminifera and calcareous nannofossil assemblages. A composite record from the Campanian to the Maastrichtian records nannofossil standard zones UC15c (CC21) to UC20a (CC26) as we...
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...
