Abstract
Structural analysis of the NW-SE oriented Alborz fault in north Qom, demonstrates young left-lateral reverse displacement evidence, based on the rake of the striations on young fault planes (45-53). Strong structural evidence exists for its previous right-lateral reverse displacement. Young left-lateral displacement evidence in NW-SE oriented oblique and strike-slip faults recently was documented in central-west (eg. Mosha and Talegan faults) and south Alborz mountains (eg. Ipak and Kusk-e-Nosrat faults) due to the compression direction of the south Caspian oceanic crust with Alborz mountains. Replacement of right-lateral reverse mechanism by young left-lateral reverse mechanism in the Alborz fault in north Qom implies that the inversion of the central-west Alborz faults is being transferred through to the same oriented faults in south Alborz mountain up to the Qom area.
