Abstract

The study area is located in some areas in Anatolian plate (Afyon, NevÅŸehir, Hasandağı-Melendiz Dag, Karadag, KaracadaÄŸ, Karapınar sites). For paleomagnetic study, it was taken oriented 324 core samples from 36 locations. First of all, natural remanent magnetizations of all samples were measured by Spiner magnetometer and then thermal demagnetization treatment was applied to each sample by MMTD60 instrument. All paleomagnetic parameters and diagrams were calculated and drew by IAPD Release 92 computer program.  Pliocene aged AF and KK sites from Afyon region have anti-clockwise rotations, respectively 200 and 39^º. Miocene aged rock samples from same region represent 55 ^º anti-clockwise rotations. Plio-Quarternary aged sites (AS and OD) from NevÅŸehir volcanic region volcanism have anti-clockwise rotations, respectively, 18 ^º and 7 ^º. Upper Miocene aged rock samples (Ağıllı-Çakıllı, OC) show 26 ^º anti-clockwise rotations. The amount of anti-clockwise rotation of Plio-Quarternary aged two locations from Hasan DaÄŸ (HD) and Melendiz Dağı (MD) are 13 ^º and 11 ^º. Pliocene aged sites from KaradaÄŸ Volcanism have 6 ^º anti-clockwise rotations. Plio-Quarternary aged site (KRP) from Karapınar area represents 22 ^º anti-clockwise rotations. 11.9 My aged rock samples (KRC) from KaracadaÄŸ show 18 ^º anti-clockwise rotations. In the second phase of study, all data, with other paleomagnetic data in and around region, was evaluated to obtain tectonic and structural implications about region. The evaluation of all data, in general, shows that rotations obtained in region could be an evidence of local tectonic events and/or the region, in this actual short geologic time, may be exposed to the active deformations.
