One of the most important tasks of interpretation of seismic data, as is known, is to determine the geologic and physical nature of seismic boundaries ...

For a number of years during seismic exploration by the reflected wave method (RWM) in the Pechenga region ground azimuthal units are used, and since 1976 - and borehole - during works by the method of vertical seismic profiling (VSP) ...

Since 1970, a combined system of surface and borehole observations by reflected wave (RW) and vertical seismic profiling (VSP) methods has been successfully applied during detailed seismic work in the Pechenga region of the Kola Peninsula. ...
