High rates of erosion and sedimentation and urban development cause the destruction or burial of fault structures and their identification signs. Investigation of the lineaments obtained from studying aeromagnetic data can be an approach to identifying buried faults. The adaptation of this method to the calculated location of visual seismic events presents better than the seismic nature of the fault processes and its geometry and depth structure in an area. In the present study, aeromagnetic data were analyzed using reduction to the pole, directional derivatives, upward continuation, analytical signal, horizontal gradient, and Euler deconvolution methods. The lineaments identified resulting from the study of magnetic anomalies were compared and reviewed with fault trends in Tehran province. The results show that many fault structures and seismic events are consistent with magnetic lineaments, and further investigation with better resolution data can provide a better answer.
