The Alasehir graben is one of the main E– W ( sensu lato ) trending structures which developed under Late Cenozoic N– S extensional tectonics in west Turkey. The age of this graben is accepted broadly as Mio‐Pliocene, but no specific data is available. An Eskihisar sporomorph association (middle Burdigalian– middle Serravallian, 20– 14 Ma) has been determined from the lower part of the graben‐fill, demonstrating that its age of initiation is Early Miocene. When this result is taken into account with the similar ages of the Büyük Menderes graben and the adjacent NE– SW trending Gördes basin, it is evident that these E– W and NE– SW trending graben/basins developed together during the Early Miocene.
