Abstarct: Magnetic method is one of geophysical methods and used for studying deposits with magnetic characteristics. The area under study located in Mahirood area, south eastern Sarbishe, southern Khorasan province. The survey was done in 40 profiles and 1000 stations with Northeastern- southwestern trend. In this thesis, to delineate anomaly’s borders and to estimate deposit’s depth, modeling has been done. After necessary pre-processing, Total magnetic, reduction to pole, upward continuation, analytic signal and vertical derivative maps were provided. Analytic signal and vertical derivative and methods were applied to delineate anomalies’ borders. Then, using two dimensional Euler and analytic signal, deposit’s depth was estimated. Finally, applying software Mag2dc two dimensional model was provided. According to the results, the area under study contains four probable magnetic anomalies which their average depth is 35 meters.
