Regional seismic works in the area of the Norilsk copper-nickel deposit were made using the seismic refraction method in the 1980s. These data were used to derive new information about the studied area. The data of eight profiles of about 2900 km total length were processed by the homogeneous functions method and reinterpreted.
Based on the seismic sections thus derived, horizontal slices were built to identify the spatial positions of structures and produce the volume image of the basement’s ledge. Seismic sections of 10–20 km in depth and horizontal slices contain the information about the boundaries, reflect the volume internal structure of sedimentary strata and basement, and show the faults.
