ABSTRACT:
A method for determining a set of surface locations lying along a predetermined line of survey beneath which there is a relatively high probability of existing subsurface mineral bodies exhibiting relatively high density and relatively low magnetic susceptibility by selecting for membership in said set those surface locations lying in regions where a local minimum of magnetic field intensity substantially correlates to a local maximum of gravitational field intensity, those surface locations lying within regions of local topographic irregularity wherein the gravitational field intensity substantially directly correlates with the surface elevation, and those surface locations lying within regions wherein a steep gradient between a local maximum and an adjacent local minimum of the magnetic field intensities substantially directly correlates to a steep gradient between a local maximum and an adjacent local minimum of the gravitational field intensities.
