A bstract Dipole‐dipole induced polarization (IP) data are displayed typically as multi‐level profiles, or as contours on vertical sectional plots referred to as pseudo‐sections. The dipole‐dipole array tends to yield IP anomalies in which the most anomalous values are displaced laterally from the source body. The data patterns are fairly interpretable on pseudo‐sections or on multi‐level profiles but are sufficiently complex to discourage the contouring of the data in plan. A method was developed for the presentation of dipole‐dipole IP data on a contour map. The method consists of a simple averaging of data which can be performed manually if desired. It yields a single output value per station which reflects all levels of the pseudo‐section, and is suitable for contouring in plan. The advantage of the technique is that it provides a quantitative picture of IP anomalies in their background or regional setting.
