Abstarct: As faults, which are fractures in the Earth’s crust, are not necessarily revealed on the surface, geophysical studies including airborne magnetic and electromagnetic methods may be utilized to detect them. In this research, to investigate the mechanism of one of the faults in Bazman area, located in 1:100000 Chah Sangi geological map and near a seasonal river called Shandagh Bala River, the acquired airborne magnetic and electromagnetic data from the area were modeled and interpreted. Modeling the airborne magnetic data was performed using Li-Oldenberg algorithm employed in the Mag3D software, and also, modeling the airborne electromagnetic data was carried out by Macnae et al. algorithm used in the EM Flow software. During this procedure, in addition to this fault, three other main faults of the area together with four minor faults, which had not been recognized in the geological studies of the area, were identified and their performances and effects on the structure and lithology of the area were investigated. In this investigation, it has been found out that a fault, named fault E, has a length that is remarkably more than the length shown in the geological map. This fault caused crushing and fracturing the adjacent rocks, and therefore, resulted in facilitation of the weathering process, and creation of a subsurface body, named body A, detected as a result of electromagnetic data modeling. Furthermore, in this study, as a result of three-dimensional magnetic data modeling, a subsurface body, called body B, was detected as a high magnetic susceptibility body. This body was created by the performances of two faults C and D, and due to the presence of olivine-basalt units, its lithology as gabbro diorite was determined
