LATE CENOZOIC FAULT KINEMATICS WITHIN BAS INS ALONG THE CENTRAL NORTHANATOLIAN FAULT ZONE (TURKEY)

The fault kinematic analysis in the Ilgaz-Kursunlu basin reveals the e volution of the regional tectonic regimes and of the states of stress in the basin, since the Upper Miocene to present. The kinematic analys is of faults affecting the Cenozoic and the substratum gives evidence that this basin has been initiated within a NNE-trending extensional t ectonic regime. Furthermore, the strike-slip phase is older than the o pening of this basin, which seems to have been initiated by an overthr ust episode which was active during the Upper Pontus filling [Plio-Ple istocene (?)]. Moreover, a Pliocene NW-trending extension could accomm odate a sinistral component of the displacement along the NAF.
