The Egertepe Perched Syncline (Turhal-Tokat)

14096

The Eğertepe Perched Syncline is located in the Middle Blacksea Part, inthe southerneast of the Turhal Plain and the city center. The perched syncline formed on Upper Cretaceous flysches. The sandy limestones forming the bedrock in the investigation area, were folded during Alp Orogeny. The fact that stratas forming anticlines were stretched and cracked during foldings ensured that they easily eroded and lowered. The synclinal part was exposed to pressures during foldings. Thus, rocks forming syncline got more resistant. Therefore while the part of the folded structure forming anticline was eroding, syncline in its upright position gained a perched synclinal view.Eğertepe is connected to Hanife Mountain through a pass. The relative height difference between Turhal Plain and the highest point of perched syncline is 166 meters. The slopes of syncline exposing to the south are steeper than those exposing to the north. For this reason, perched syncline has an asymmetric view.
