Özet

The Alasehir graben is one of the main E-W (sensu late) 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 Buyuk Menderes graben and the adjacent NE-SW trending Gordes basin, it is evident that these E-W and NE-SW trending graben/basins developed together during the Early Miocene.
