Simulation Of A Salt Dome Using 2d Linear And Nonlinear Inverse Modeling Of Residual Gravity Field Data, Soheyl Pourreza, Farnush Hajizadeh

Bulletin of the Mineral Research and Exploration

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 accuracy of method is tested on two synthetic gravity anomaly from different models, while the data are noise- free and corrupted with noise. In this paper, We 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 …
