Abstract

In the NNW of Ankara around Yuvaköy, the north dipping thrust faults between ophiolitic mélange and Neogene sedimentary rocks have been shown as field evidence of the "Ankara Orogenic Phase", suggesting the continuation of intracontinental convergence until the Pliocene, as recently re-reported by scientists. To test this recent report, the tectonic contact between ophiolitic mélange and Neogene sedimentary rocks was re-mapped and geophysical methods were used to determine the dip direction of the tectonic contact. This study shows that the tectonic contact is a south dipping normal fault and there is no field evidence of post-Miocene N-S contraction in the region.
