Abstarct: Efforts to identify subsurface resources have become widespread, and geophysics is one of the most appropriate tools for identifying these structures. The main purpose of geophysical methods is to identify as accurately as possible the physical properties of geological structures. To achieve this goal, modeling is one of the most successful methods of interpreting geophysical data;The result is a more accurate understanding of 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 this article, we have tried to use two-dimensional inversion of software (Geosoft oasis montaj) and three-dimensional constrained magnetometric data using Lee and Oldenberg software algorithm (MAG3D) to interpret the results correctly. In order to make the best use of the algorithm, first its application on artificial data with noise is investigated and baxsed on the degree of conformity of the results with the original answer, this method is used to invert real data. In this research, magnetometric data of Khoranagh exploration area located in the northeast of Yazd province have been modeled. The results of the study indicate that there are three mineralization areas in the west of the area. In the western massif, three areas with different depths and expansions were found, two of which were almost the same depth and the other with less extent and depth.
