<p>EXPLORATION SYSTEM FOR ENHANCING THE LIKELIHOOD OF PREDICTING LITHOLOGY OF EARTH FORMATIONS ASSOCIATED WITH DEPOSITS OF ORE, MARKER ROCK AND/OR ECONOMIC MINERALS The present invention provides for the accurate mapping of shallow crustal earth formations by means for refractive seismic waves to identify structure, elastic parameters and lithology of the strata undergoing survey to indicate deposits of ore, marker rock, economic minerals and the like. After a "rollalong" technique has been used in the field to collect the refraction data and preliminary processing steps undertaken in which there are provisions for (i) accurate separation and determination of seismic shear and compressional responses; (ii) stacking displays that allow for accurate identification of shape of the surveyed strata; and (iii) final depth displays of the refracting bed segments associated with seismic shear and compressional wave velocities as well as Poisson's ratios, in accordance with the present invention, additional processing then occurs. The added processing indicates lithology of the earth formation to a surprising degree based, inter alia, on multidimensional space searching techniques.</p> |
