In the region the basement is made up of Paleozoic-Mesozoic high-Massif. These rocks are covered unconformably by the Paleocene-Middle Eocene aged continental and marine rocks of the Ayhan group. Oligocene-Quaternary rocks rest on the over the older units with angular unconformity. The rocks of Ayhan Group which originally represented a back-arc settings were deformed and gained thrusted-imbricated and poly-phase folded structures before the Middle Miocene time. The dimensions of the folds vary from outcrop to the map scale. The first phase of the deformation generated sheath folds and Type 3 refolded folds which are typical for shear zones, in the Paleocene-Eocene aged rocks. According to the layer thickness variations, the folds are generally Class 1C flattened parallel folds and Class 2 similiar folds in shape. Rarely, Class 1A and Class 1B folds are also present. The flattening ratio (2/ 1) 1/2 of Class 1C folds varies from 0.25 to 0,71. According to the Fourier analysis, it is observed that the folds shapes in the region mostly change from the sinousidal to the chevron form, and although it is rare the box fold can be observed. The b1 and b3 Fourier coefficients values vary from 4,14 to 0, and from-0,61 to 0,02, respectively. The Dip Isogonal Classification of Folds has shown that the folds in the competent rocks (limestone and sandstone) generally are Class 1B and 1C, and in the incompetent rocks (Mudstone, shale and siltstone) are Class 1C and 2.eninfo:eu-repo/semantics/openAccessNevşehirFoldsDip IsogonsPaleocene-EoceneFourier AnalysisConference Object
