Abstract
On the basis of analysis and generalization of the extensive seismic information obtained over the last forty years, the modern concept of the deep crustal structure in the central Karelian Craton is developed. The tomographic models are reconstructed, the stratification of the Earth’s crust and geometry of seismic boundaries are refined, and the subsidence of the boundary between the crust and mantle down to a depth of 60 km is noted. The comparison and integrated interpretation of the sections studied by the common depth point (CDP), deep seismic sounding (DSS), and converted-wave methods together with the available geological data shows that the results derived by different seismic methods differ markedly. However, since various methods have revealed the different characteristics of the medium, the entire body of seismic evidence can be used for geological interpretation.
