Optimal density model of the lower layer of sedimentary strata has been selected by a method of multi-variant analysis applying the data of seismic-gravity modeling along the DSS profiles crossing the transitional zone from the Dnieper graben to the Donbass. Difference field from this model, which three upper levels had been fixed earlier, were interpreted by a method of three-dimensional gravity modeling. The obtained solution - increase of density of consolidated crust along the axis of aulacogene and parallel to the Northern marginal fault has been compared with the available models of the Dnieper graben and the Donbas. Conclusions have been made as to similarity and differences in the structure of units, which make the Dnieper-Donets aulacogene.
