Tectonic escape is frequently considered to result from compression in a collisional belt, a free boundary opening the way to lateral extrusion of rigid blocks. However, Anatolia the complex tectonic history provides an opportunity to better understand why a widespread late Cenozoic extension occurs instead of generalized compression In contrast to common opinion, we argue in this article that the major thickening the Anatolian plateau did not occur during late Cenozoic times as a consequence of the Africa-Arabia collision with Eurasia and related compression. When examin ing the distribution of the late Cenozoic deformation in eastern Anatolia, the main ar gument is that the region was subjected largely to extension and strike-slip tectonics Compression was limited to the narrow eastern Taurus belt and to a north-south strip comprising the Afsin and Gürün arcs and the Sivas basin. This is shown by a review of the literature and by complementary examination of radar and regional-scale Dig ital Elevation Model imagery. A second argument is that a major crustal thickening occurred prior to the late Cenozoic during a major collisional event that took place the Eocene. Crustal thickening was followed by extensional collapse of Anatolia dur ing the Neogene–Quaternary after the opening of the Aegean basin free border during the Oligocene. Consequently, the escape of Anatolia largely implies body forces previously stored in the lithosphere, inducing extensional collapse over crustal-scale detachments, triggered by the onset of a free boundary in the west. This tectonic evo lution is related to the progressive propagation of the extension from west to east, which induced eastward propagation of the North Anatolian fault forming the northern boundary of the area submitted to tension.
