Ichnology of the miocene güneyce formation (southwest Turkey): Oxygenation and sedimentation dynamics

Abstract

The Güneyce Formation is well exposed in the Lake District of southwestern Turkey. It was deposited in the early Miocene in the Neotethys ocean and contains a large variety of trace fossils. The following ichnotaxa were recognized: Chondrites intricatus, C. targionii,?Cosmorhaphe isp., Helminthopsis isp., Helminthorhaphe f exuosa, Lorenzinia isp., Naviculichnium marginatum,?Nereites isp., Ophiomorpha rudis,?Phycosiphon incertum, Planolites beverleyensis, cf. Rhizocorallium isp. and T alassinoides suevicus. There is a lateral trend from proximal turbiditic successions to distal low-oxygen shaly mudstone. Ophiomorpha rudis ichnosubfacies, Paleodictyon ichnosubfacies of the Nereites ichnofacies and Zoophycos ichnofacies were identif ed. © Tübi̇tak.
