VELOCITY SPECTRA - DIGITAL COMPUTER DERIVATION AND APPLICATIONS OF VELOCITY FUNCTIONS

Multifold ground coverage by seismic techniques such as the common reflection point method provides a multiplicity of wave travel path information which allows direct determination of rootmean-square velocities associated with such paths. The paper outlines the fundamental principles for calculating velocity spectra displays. Examples are included which demonstrate the depth and detail of geological information which may be obtained from the interpretqtion of such displays.
