Detection of a waveguide in the basement of the northwestern shelf of the Black Sea according to the results of reinterpretation of the DSS materials of profiles 26 and 25
Results of reinterpretation of DSS materials along the profiles worked out within north-western shelf of the Black Sea near 45 years ago are given. Those are two seismic profiles crossed the shelf area: latitudinal DSS Profile 26 (Zmiyinyi Island - Tarkhankut Peninsula) and Profile 25, which crosses...

Geofizicheskiy Zhurnal| Резюме: | Results of reinterpretation of DSS materials along the profiles worked out within north-western shelf of the Black Sea near 45 years ago are given. 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. |
