Three-Dimensional Gravity Inversion in the Presence of the Sediment-Basement Interface: A Case Study in Utah, USA

We introduce a novel approach to three-dimensional gravity inversion in the presence of sediment-basement interface with strong density contrast. This makes it possible incorporate known information about basement depth inversion. It also allows user determine depth-to-basement initial phase. One can then use this constrain final First, generates model based on 3D Cauchy-type integral representation field. Then, second phase, full voxel-type applies determined first phase as an priori constraint. Bouguer anomaly data observed Utah, USA. The results generated top layers earth’s crust, including unconsolidated sediments and crystalline basement.
