Disclosed is a well logging system using the output of a dipmeter tool, preferably a three or more trace tool, to produce a map showing at least one or more of the following characteristics of the earth formations surrounding a borehole: the location of a depth zone in which the formation dips are mutually consistent within defined criteria, the structural dip within a zone, the formation dips within a zone rotated to account for the shown structural dip of the zone, the confidence limits of the magnitude and azimuth of a shown structural dip and an azimuth frequency polar histogram of the dips within a zone. In addition, the system identifies sedimentary patterns within a zone, such as blue and red patterns and shows their nature and characteristics.
