Determination of density contrasts for a three-dimensional sub-surface intermediate layer

摘要: The quantitative determination of the variable density contrasts for an intermediate horizontal layer has been demonstrated. In particular a sub-surface dipping dike with priori depth-dependent was adopted as forward model to project gravity anomaly effect above Earth surface. location and in series layers causative structure have recovered by means inversion analysis. Density recovery errors less than 8.0 percent were realized depth 2.00 km on maximum synthetic 10.0 mGals that is better comparison constant models. Finally demonstrate efficacy inverse analysis study, entire process successfully applied real field data, i.e., residual micro-gravimetry site and/or localized structures Matsumoto Basin, Chubu District—Japan.
