a. A geophysical survey using the resistivity method. An assembly of
electrodes spaced at a constant distance is moved along profiles,
resulting in lateral variations in resistivity being shown. In favorable
terrain, the test shows the existence of faults that have thrown strata of
different resistivity against each other; similar relationships result in
the detection of an anticline, a syncline, or an underground channel.
b. A survey by the resistivity method in which an array of electrodes is
moved along profiles to determine lateral variations in resistivity.
