Theoretical simulation of the effect of deformation on local gravity in a density gradient zone *

:We modeled the effect of the deformation of a Density Gradient Zone (DGZ) on a local gravity field using a cubical model and introduced a new method to simulate a complex DGZ (CDGZ). Then, we analyzed the features of the model for the influence of the deformation of the DGZ on the local gravity field. We concluded that land-based gravity is not sensitive to the thickness of the DGZ and that the magnitude of the contribution of the DGZ is one order less than that of the volume strain with the same displacement.
