DEEP REFLECTION SEISMOGRAPHY IN STUDYING THE EARTHS CRUST OF THE UKRAINIAN SHIELD

The results of studies of the Ukrainian Shield (USh) basic structures (Sura sinclinorium, Korsun'-Novomirgorod pluton, Krivoy Rog structure, Novoukrainka massif, Central and Southern USh) by the seismic reflect ed CDP-method are considered and analysed. The structures given show h igh effectivity of the seismic reflected CDP-method in studying USh Ea rth's crust structure. The wave field is dominated by single reflectio ns and their series associated with tectonic disturbances and contacts of rocks of different composition. Some of these results when compare d with similar investigations in the region of post-Riphean consolidat ion show that there is much in common between the crystalline complexe s of pre- and post-Riphean consolidation in the peculiarities of spati al reflection distribution on the CDP-sections. Similarity of reflecti vity which we marked for the first time give us favourable perspective s for creating similar seismic models of the consolidated crust irresp ective of the last folding age.
