On the choice of velocity for construction of reflecting boundaries in sections of the Pechenga area
Abstract
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. ...
