In gravity field inversion we usually dealing with underdetermined problems and for obtaining realistic solutions can introduce a depth-weighting function to the inversion algorithm.We employ a linear inversion method for determining the underground density distribution of the gravity causative mass.The validation and accuracyof method is tested on two synthetic gravity anomaly from different models, while the data are noise- free and corrupted orange zinger tomato with noise.In this paper, We moen finney also invert the 2D gravity anomaly produced by a salt dome from the northwest of Iran.
The salt domes in the region under investigation are a rich source of Potash.The inverted structure demonstrate on average a depth to top and bottom of 27 m and 65 m, respectively.For comparison, we also have simulated the salt dome using the nonlinear inverse modeling.The results are mostly similar.
