Abstract

In this study, horizontal gradient and analytic signal methods have been applied to the reduced aeromagnetic data poled to Iran, to explore subsurface structures in the region. By using these two methods, it is possible to present a map of major geologic-magnetic structures especially large-scale faults displaying magnetic signal in the region. Qualitative and quantitative results of this study were then prepared as maps and compared with previous studies. Finally, the agreements and disagreements observed against the previous studies were explained.
