The position of Akkaşdağı mammal locality in the neo-tectonic framework of Çankırı basin, Turkey

This paper presents tectonic features of the southern part of Çankırı basin where is located the rich late Miocene mammal locality of Akkașdağı. Field observations and mapping demonstrated that the late Miocene-Pliocene deposits unconformaly overlie the pre-Neogene basement. The overall thickness of Neogene deposits increases toward NE. Horst-graben structure of pre- Neogene basement indicates that the Miocene fill took place under extensional tectonics which enlarged the basin toward SW.
