The Tectonic Control on the Geomorphological Landscapes of Turkey

The multifarious landforms making up the landscapes of Turkey are largely controlled by tectonic activity since the last 11 Ma, at most 23 Ma making surface correlation by elevation alone hazardous. This “neotectonic episode” is characterized by tectonic escape that created five neotectonic provinces in the country: (1) the shortening east Anatolian province corresponds to the eastern Anatolian highlands; (2) the gently E–W-shortening north Turkish province; (3) extensional west Anatolian province; (4) the gently NE–SW-shortening and NW–SE-extending Ova Province; and (5) the border folds (Assyrides) of the northernmost Arabian Plate. In each of these provinces, the rate and history of uplift, history of climate and rock types have dictated the details of land sculpture. Volcanic landforms dominate in the east, and karst dominates in the south. The other regions display more varied morphological types controlled mainly by rock type and climate. Although Turkey is moderately endowed in fossil glacial and periglacial forms, active glaciers are few and restricted to the high mountains in the extreme south-east of the country.
