ABSTRACT:
A geophysical method of exploration including processing and displaying seismic data so as to enhance geophysicists' ability to evaluate and interpret subtle variations in the earth's geological and lithological structure. In particular, an exponentiated phase signal is obtained for a complex signal formed from seismic data exponentiated to a selected power. Displays of the exponentiated phase signal can be produced which visually highlight subtle variations in the earth's geological and lithological structure.
