AbstractAbout the AuthorsReferences

In the case of seismic density modeling of sedimentary basins, it is necessary to exclude fromthe observed gravitational field the effect created by inhomogeneities of the lower part of the crustal section. The article offers one of the approaches tothe geological field reduction, implemented through the construction of a 3D density model for the entire thickness of the earth’s crust and upper mantle. A fragment within the study area is selected from the constructed 3D model and its gravitational effect is calculated. Various options for implementing this approach are considered, depending on the amount of a priori information. The technological base of the method is GIS INTEGRO.
