IP & SP
Induced Polarization (IP) method is one of the most widely used techniques in mineral exploration and mining industry and it has other applications in groundwater surveys, geotechnical engineering and environmental investigations. Today IP is the primary tool used to explore for several important types of mineral deposits, especially porphyry coppers, bedded lead/zinc and sulphide-related gold deposits. IP is an unique geophysical methods employed in mineral exploration, in that it is based on an interface electrochemical phenomenon rather than on a purely physical property of rocks or minerals.
Spontaneous Potential (SP) method is based on the surface measurement of natural potentials resulting from electrochemical reactions in the subsurface. SP is based on the surface measurement of natural potentials resulting from electrochemical reactions in the surface. It is a great too l to used in base metal exploration, to detect the presence of massive ore bodies, in contrast to the IP method which is used to predominantly to investigate disseminated ore bodies.
