Abstract

The seismic-gravity modelling of the lithosphere consists of a density model, which is derived from a seismic section and which satisfies the observed gravity field. A direct relation is usually assumed between seismic velocity and density. If in this process a discrepancy occurs between the calculated and the observed gravity fields, then the fields are discarded by introducing supplementary density inhomogeneities into the section not detected by the seismic method. As a rule, the section satisfying with high accuracy the gravity field is rather easily obtained, but the doubt remains as regards its authenticity if the general ambiguity of solution is taken into consideration.
