The stratigraphical position of Kemiklitepe fossil locality (Eşme, Uşsak) revised: Implications for the Late Cenozoic sedimentary basin development and extensional tectonics in western Turkey
Abstract:Unlike earlier studies attributing the Kemiklitepe fossil locality to the İnay Group, the present study indicates that it is to be assigned to the Asartepe Formation that unconformably overlying the İnay Group. This seems to verify the early Middle Miocene age of the İnay Group, previously determined by isotopic dating and palynological analyses. However, the early Middle Miocene age and the overall undeformed nature of the İnay Group do not concur with the regional two-stage extension model proposing a compressional phase during the Miocene/Pliocene interval. The correlation of the Asartepe Formation bearing the Kemiklitepe fossil locality further to the north indicates that a NE-SW trending fault was active during the Late Miocene. Recent studies modelling the uplift history of the region are unconvincing because they ignore Late Miocene activity on the NE-SW trending faults and assume a timing of incision of the İnay Group after the Late Pliocene (∼3Ma) in their calculations.
