Abstract
The results of CMP seismic data acquisition along regional deep profiles that cross large tectonic elements in the east of the East European Platform are considered. It has been established that the Zhiguli-Pugachev Arch and the Stavropol Depression (southern part of the Melekess Basin), as well as the Volga-Kama Anteclise and Pericaspian Syneclise, conjugate along reverse-thrust faults extending to the lower crust and Moho discontinuity. The position of the southeastern reverse-thrust boundary of the South Tatar Arch has been substantially specified in plan view and illustrated by seismic sections. Based on the results obtained, it is suggested that reverse-thrust faults of different orders are widespread in petroleum provinces in the east of the East European Platform, and this suggestion should be used in geological exploration. The CMP seismic data acquisition is efficient in studying the junction zones of large tectonic elements. It also provides insights into the deep structure of the Earth’s crust and its relationship to the structure and petroleum potential of the sedimentary cover and localization of oilfields. It is expedient to reprocess and integrate earlier seismic data in order to compile tectonic (tectonodynamic) regional maps on a new methodical basis.
