Abstract: The effects in Sultan Mountains ,and their surrounding, of the Helvetian phase of the Alpine Orogeny werevery strong. Sultan ,and Emir Mountains uplifted as a block ,and Akşehir ,and Eber basins depressed as a graben due totectonic movements. Violent fluvial erosion began in Sultan Mountains ,and excessive sedimentation prevailed in the depressed areas. Akşehir, Eber ,and Karamuk basins were occupied ,by lakes since Miocene times. At the end of the UpperMiocene ,and in the Early Pliocene, violent tectonic movements became increasingly active. Finally the fault systems of Sul-tan Mountains were rejuvenated ,and new fault systems developed. Especially, a synthetic fault system formed as a parallel dip-slip normal fault system located along the north ,and north-east edges of Sultan Mountains. On the other hand,synthetic ,and antithetic fault system developed in depressed areas.There are two breaks in slope (threshold) on the stream profiles of Sultan Mountains. These breaks in slope havedirect relation to faults.Graaulometric ,and cumulative curves of Pliocene ,and Plioquaternary deposits to the north ,and north-east of Sultan Mountains, are logharltmic. These curves, too, indicate an accelerated process of sedimentation.
