Methods of studying by seismic survey of complex structures of the upper part of the consolidated crust of continents
Abstract
Based on the vast experience of seismic exploration in oil- and gas-bearing areas, the methodology and systems of observations using reflected and refracted waves as applied to the study of gentle structures of sedimentary rocks have been well developed and are still being improved. At the same time, in recent years, the seismic exploration method is increasingly used to study the consolidated crust and, in particular, structures composed of highly metamorphosed and crystalline rocks in regions where ore deposits are being explored for. Under these conditions, seismic exploration is tasked with studying very complex folded and highly dislocated structures formed by rocks that are relatively poorly differentiated in terms of elastic wave propagation velocity.
