AB: Western Anatolia is characterized by a number of east- west trending grabens and horsts. They have formed under approximately north- south extension according to the analysis of the seismic data. The views on the history of development of the grabens are conflicting. To solve this long lasting controversy new data have been collected from a mapping project revealed that the generation of the present morphology of the region is much more complex than what have been suggested previously; The present east- west trending grabens are very young; post Miocene in age. Prior to their development, the region has suffered different phases of deformation which may be summarized as follows; a. a pregraben stage b. Opening of North-South trending graben stage. c. An earlier stage of North-South extension d. An interrupting stage when the region undervent a regionwide erosion. e. Later stage of North South extension. In this paper, data derived from different areas, based on the mapping conduct, will be documented to support each of these phases, and their timing will be discussed.
