A METHOD OF GELOGICAL EXPLORATION FOR LOCATING A BODY HAVING A HIGH VELOCITY OF PROPAGATION FOR SEISMIC WAVES, SAID BODY HAVING A COMMON BOUNDARY WITH A LOWVELOCITY LAYER EMBEDDED IN AND BOUNDED ABOVE AND BELOW BY MEDIA OF HIGHER VELOCITY, COMPRISING THE STEPS OF APPLYING TO SAID LAYER AT A POINT IN SAID LAYER REMOTE FROM SAID BODY SEISMIC WAVES OF HIGH ENOUGH FREQUENCY THAT A MAJOR PORTION OF SAID WAVES WILL BE PROPAGATED ALONG SAID LAYER AS A WAVE GUIDE AND REFLECTED FROM SAID BODY BACK ALONG SAID LAYER, DETECTING SAID REFLECTED WAVES ARRIVING AT A POINT IN SAID LAYER, AND MEASURING THE MAGNITUDE OF SAID REFLECTED WAVES AT SAID LAST-MENTIONED POINT AS A FUNCTION OF TIME.
