Abstract
A method of induced polarization geophysical surveying which derives meaningful parameters relative to the subsurface strata in both time domain and frequency domain for comparison and/or deductive data compilation and graphic depiction. The system includes a current source as energized by an input wave generator providing an input signal of predetermined frequency content, amplitude relationship and duration; in addition, a plurality of energy receiving detectors are utilized in equi-spaced array such that differential electrical measurement between successive detectors may be gained during each single input energy operation. Such differential electrical measurements are further susceptible of cross correlation relative to the input current signal to provide increased signal-to noise differentiation with respect to usable induced polarization resultant values.
