Gravity surveys have been used in investigations of wide range of scales such as tectonic studies and mineral explorations and in engineering and environmental problems. Geometric shapes and especially prisms are useful in geophysics for modeling two and three dimensional (2D and 3D) underground bodies that produce gravity anomalies. Modeling in 2D and 3D are an important procedures enabling 2D and 3D information about mineralization to be leveraged for the computation or extraction of the key parameters. In this paper, we employ the inversion algorithm of for 3D inverse modeling and a 2D nonlinear inversion method for a real gravity data set related to metal deposit from Iran.
