“…The circa 2000 km long east-west trending İzmir-Ankara-Erzincan suture zone (Brinkman et al, 1972) forms one of the most important suture lines in Turkey, and the oceanic domain related to it is generally known as the İzmir-Ankara Ocean. The İzmir-Ankara-Erzincan suture zone divides Turkey into two main tectonic units, the Pontides to the north and the Anatolides-Taurides composite block to the south (Göncüoğlu et al, 2000;Moix et al, 2008;Okay et al, 1996;Şengör & Yılmaz, 1981). The Pontides comprise the Rhodope-Strandja, İstanbul, Zonguldak and Sakarya zones.…”

This study focuses on a basin-floor turbiditic system in an Eocene foredeep basin, using facies analysis supplemented with micropalaeontological and ichnological data. Sediment dispersal processes are interpreted from sedimentary facies, and the morphogenesis, spatial relationships and stratigraphic distribution of facies associations are used to reconstruct the behaviour and morphodynamic evolution of the turbiditic system. The case study sheds more light on the development of submarine channels and related patterns of overbank sedimentation in narrow foreland basins, and contributes to a better understanding of the geological history of the Central Pontides.The lower to middle Eocene Kusuri Formation in the Sinop Basin, north-central Anatolia, is a succession of siliciclastic turbidites ~1200 m thick, well-exposed on the Turkish Black Sea coast. The deposition occurred in a west-trending foredeep trough of the Central Pontides, ~30 km wide and > 150 km long, and involved a deep-water axial dispersal system supplied with coarse sediment by a fluvio-deltaic feeder draining the emerged adjacent foreland of the Eastern Pontides. Sedimentary facies include hemipelagic 'background' mudstones, thin muddy turbidites and 'classic' Bouma-type turbidites, a wide range of non-classic turbidites attributed to low-and high-density sustained currents, and gravelly debrisflow deposits. These facies form four major associations:1 mudstones interspersed with thin turbidite sheets; 2 broad depositional lobes with thickening-upward bedding trends; 3 poorly defined wide palaeochannels, solitary sinuous palaeochannels and multistorey palaeochannel complexes; 4 packages of thin overbank turbidites with tabular, wedge-shaped or sigmoidal bedding.The first assemblage forms the lowermost and uppermost part of the Kusuri Formation, whereas the others occur in its middle main part. The poorly defined palaeochannels are 20-25 m thick, typically overlie the depositional lobes and are themselves overlain by the sinuous palaeochannels, 20-30 m thick and ≤ 400-500 m wide, which suggests that the former channels tended to evolve into the latter. The sinuous channels show lateral accretion (point bars) indicating meander-bend expansion combined with a marked downstream translation, and their depth/width aspect ratios are much lower than those of many modern submarine channels. The multistorey complexes of sinuous palaeochannels are 100-160 m thick and estimated to be ≤ 3-5 km wide. The vertical stacking of multistorey channels is attributed to the growth of syndepositional blind-thrust anticlines on the basin floor. The overbank facies assemblages indicate basin-wide flows (tabular bed packages),

 Multi-phase intercontinental collision is identified in western Anatolia by sedimentary basin changes  Sedimentary provenance change indicate collision was at 76 Ma, but significant thickskinned deformation was delayed until 54 Ma  The 20 Myr duration of initial collision can be explained by three multi-stage mechanisms involving changes in plate coupling manuscript submitted to Geochemistry, Geophysics, Geosystems
