摘要

Three different deformation phases have been recognized in the southern part of the Çank?r? Basin from (1) the major structures and (2) through using paleostress inversion techniques for fault slip data. The deformation phases recognized from the paleostress data are correlated with those recognized from the major structures and dated accordingly. The first phase occurred in the Late Paleocene to pre-Burdigalian and is characterized by an oblique σ₂ and NNE–SSW to NE–SW trending subhorizontal σ₁ and WNW–ESE to NW–SE trending σ₃ patterns which indicate transcurrent deformation associated with a combination of thrusting and strike slip faulting (transpression) possibly due to indentation of the K?rsehir Block to the Sakarya Continent. The second phase occurred from the Burdigalian to the Serravallian and is characterized by a subvertical σ₁ and oblique σ₂ and σ₃, which indicate oblique extension associated with normal faulting possibly due to a post-orogenic collapse. The third deformation phase is characterized by a vertical σ₂ while the other stresses were horizontal, which indicate regional transcurrent tectonics, which is correlated with the current transcurrent tectonics controlled by the North Anatolian Fault Zone.
