“…WBF -West Black Sea Fault. age. In the lower part of the Trakya Formation, there are tongues of in situ shallow-marine upper Visean bioclastic limestones (Kaya & Mamet, 1971). The limestones pass up into richly fossiliferous shales and siltstones of latest Early Devonian (late Emsian) age, which are in turn overlain by thinly to irregularly banded marly nodular limestones, marls and shales of latest Early Devonian (Late Emsian) to earliest Carboniferous (Tournaisian) age, deposited in deep water (Çapkınoglu, 2000, 2005Göncüoglu, Boncheva & Göncüoglu, 2004).…”

Sinistral transport along the Trans-European Suture Zone: detrital zircon–rutile geochronology and sandstone petrography from the Carboniferous flysch of the Pontides

The Lower Carboniferous flysch of the Istanbul Zone in Turkey is an over 1500 m thick turbiditic sandstone-shale sequence marking the onset of the Variscan deformation in the Pontides. It overlies Lower Carboniferous black cherts and is unconformably overlain by Lower Triassic continental sandstones and conglomerates. The petrography of the Carboniferous sandstones and the geochronology and geochemistry of the detrital zircons and rutiles were studied to establish the provenance of the clastic rocks. The sandstones are feldspathic to lithic greywackes and subgreywackes with approximately equal amounts of quartz, feldspar and lithic clasts. The amount of quartz and lithic fragments decreases upwards in the sequence at the expense of feldspar. The lithic fragments are dominated by intermediate volcanic rocks, followed by metamorphic and sedimentary rock fragments. Coarse lithic fragments are generally granitoidic. In the discrimination diagrams, sandstone samples lie mainly in the field of dissected arc. A total of 218 detrital zircons and 35 detrital rutiles from four sandstone samples were analysed with laser ablation ICP-MS. The detrital zircons show a predominantly bimodal age distribution with Late Devonian to Early Carboniferous (390 to 335 Ma) and Cambrian-Neoproterozoic (640 to 520 Ma) ages. The remaining 9 % of the analysed zircons are in the 1700-2750 Ma range; zircons of the 700-1700 Ma age range are absent. The REE patterns and Th/U ratios of the zircons are consistent with a magmatic origin. With one exception (Neoproterozoic), the rutile ages are Late Devonian-Early Carboniferous and their geochemistry indicates that they were derived from amphibolite-facies metamorphic rocks. Sandstone petrography and detrital zircon-rutile ages suggest one dominant source for the Lower Carboniferous sandstones: a Late Devonian to Early Carboniferous magmatic and metamorphic province with overprinted Neoproterozoic basement. Late Devonian-Early Carboniferous magmatic and metamorphic rocks are unknown from the Eastern Mediterranean region. They are, however, widespread in central Europe. The Istanbul Zone is commonly correlated with the Avalonian terrranes in central Europe, which collided with the Armorican terranes during Carboniferous times, resulting in the Variscan orogeny. The Carboniferous flysch of the Istanbul Zone must have been derived from a colliding Armorican terrane, as indicated by the absence of 700-1700 Ma zircons and by Late Devonian-Early Carboniferous magmatism, typical features of the Armorican terranes. This suggests that during Carboniferous times the Istanbul terrane was located close to the Bohemian Massif and has been translated by strike-slip along the Trans-European Suture Zone to its Cretaceous position north of the Black Sea.

Except for a few Lower Carboniferous foraminifers found in shally lenses (Kaya & Mamet 1971) in the lower part of the formation, these mass-flow deposits are barren.

The Cebeciköy Limestone from the Variscan flysch of the Ýstanbul Terrane is assigned to the foraminiferal MFZ11 zone (late early Viséan, formerly V2a). This zone is essentially the range zone of Uralodiscus rotundus. Additional bioevents are proposed for characterizing the upper part of this biozone (MFZ11B subzone): the LAD of Eoendothyranopsis and the FAD of Pararchaediscus and Conilidiscus. The majority of foraminifers and algae, belonging locally to MFZ11 are well-known, except for the following taxa: Issinella luteotubulifomis sp. nov., I. enormis sp. nov., Vicinesphaera parasqualida sp. nov., Planogloboendothyra modesta sp. nov. and Endothyra irinaeformis sp. nov. The Istanbul Terrane is connected with the southern branch of the Palaeotethys, whereas the Zonguldak Terrane is connected with the northern branch of this one.•
