When studying seismic exploration of ore areas, the rate for the construction of reflecting boundaries can not always be selected by methods developed in oil seismic exploration for horizontal layered media. This is due to the complexity of crystalline rock structures, intensive tectonics and magmatism, which determine the regularities of elastic wave velocity distribution in sections of ore districts. The study of these regularities in connection with the geologic structure of the Pechenga region of the Baltic Shield allowed us to substantiate the method of rate determination for the construction of reflecting boundaries on seismic sections of the Pechenga structure. ...

To study the deep structure of the Pechenga ore district, the reflected wave seismic (RWS) method has been successfully applied in recent years. Consistent complication of the tasks solved in this case, causes the need to detail the ideas about the velocity section of the studied area, for which data from both borehole and ground seismic observations are used.
