Inversion of gravity data for depth-to-basement estimate using the volume and surface integral methods: model and case study

In this thesis, I applied Cauchy-type integral-based depth-to-basement estimation method to a variety of models to test the reliability of the method in different geological scenarios. I also inverted for three-dimensional (3D) subsurface anomalous density distribution with constrained model parameters in order to produce more compact inversion results. I demonstrated several single-block and multiple-block synthetic model results produced by constrained 3D gravity inversion. I also display results for Cauchy-type integral-based 3D depth-to-basement inversion of simple/complex basin models. The results from both methods are nicely consistent with true models at a very low misfit level and a fast convergence. A case study is presented at the end of our paper for both methods, and results for both methods are used to do interpretation jointly.
