Abstarct: Attempts to identify subsurface resources have expanded greatly and geophysics is one of the appropriate tools to identify these structures. The main goal in geophysical methods is to identify the physical and geometric characteristics of geological structures as accurately as possible. To achieve this goal, the modified pole reversal method is one of the methods of interpreting magnetometric data in geophysics; The result of which is to find and understand the subsurface structures such as source shape, depth, lateral, width, depth elongation, and so on. Determining these parameters has a direct and significant impact on subsequent decisions; Which can be effective in managing exploration costs. In the article, it has been made to obtain a correct interpretation using the polereturn filter and the Lee-Danimiller algorithm the value of the angle of inclination and diclination in the calculation of the return filter to the reduce the magnetic pole can be obtained The artificial data were analyzed along with the noise and baxsed on the degree of conformity of the results with the main answer, this method was used for real data. In this study, the magnetometric data of the Ardakan city exploration area located in the northwest of Yazd province have been examined. The results of the study indicate the existence of three mineralization areas in the north and south of the area, the northern massif of the area is larger than the other two areas and has a higher exploratory importance.
