Those are two seismic profiles crossed the shelf area: latitudinal DSS Profile 26 (Zmiyinyi Island - Tarkhankut Peninsula) and Profile 25, which crosses the western part of the Black Sea in sub-longitudinal direction. The wave field is character-ised by some special features in observed travel-time curves, which are indicative on the presence of wave guides here (the layers with decreased velocities). Velocity simulation produced by ray-tracing method along two profiles 26 and 25 indicated the presence in the basement and the upper part of consolidated crust of an inversion zone of complicated structure.The nature of a distinguished zone might by related to the occurrence of fault zones filled with rocks of increased jointing and porosity and the fluids, which may have under conditions of the north-western shelf hydrocarbon composition.</a></div>}, number={6}, journal={Geofizicheskiy Zhurnal}, author={Baranova, E.
