Evidence of orbital forcing in lake-level fluctuations in the Middle Eocene oil shale-bearing lacustrine successions in the Mudurnu-Göynük Basin, NW Anatolia (Turkey)

► Middle Eocene of this basin comprises lacustrine to lagoonal deposits. ► Cyclostratigraphic studies show distinct orbital control in a foreland setting. ► Coarser cyclicity observed is originated from changes in loading of thrust sheets. Mudurnu-Göynük basin of the Sakarya Zone in NW Anatolia comp...

Description
Summary:► Middle Eocene of this basin comprises lacustrine to lagoonal deposits. ► Cyclostratigraphic studies show distinct orbital control in a foreland setting. ► Coarser cyclicity observed is originated from changes in loading of thrust sheets. Mudurnu-Göynük basin of the Sakarya Zone in NW Anatolia comprises ca. 1500m thick Paleocene–Eocene terrestrial to shallow marine succession overlying the Late Cretaceous deeper marine progradational fore-arc sediments. Formed in a foreland setting in relation to southerly situated İzmir–Ankara suture zone, this terrestrial succession (regionally known as Kızılçay group) comprises a thin (
