Mike I P is................................................. Just a tool and one that is declining in popularity, "read on" "BULLY"! Resistivity Natural electrochemical reactions near the surface of the earth, where metallic sulfides may be subject to weathering, can be used in the simple self-potential (SP) method. The measuring instrument detects the electrical current developed during the weathering of the sulfide. A shortcoming of the SP method is the frequency and variety of spurious responses obtained. A more popular application of the electrical method is where controlled electrical energy is applied to the earth and the resulting electrical behavior of the ground is observed at closely spaced stations at regular intervals over the surface. An adaptation much used during the past decade induced polarization (IF) where the conductivity of mineralized ground changes with variation of frequency of the applied current, while the conductivity of barren ground remains constant. As with the SP method, IP "often produces misleading results" and use of the method has declined recently.
