Azimuth versus dip plot

One of a series of SCAT plots introduced by Bengtson (1981), it is a bivariate scatter plot of azimuth (X-axis, scaled 180°-0°-180°) versus dip (Y-axis, scaled 0°-90°, positive up) for picked or calculated planar features.  If a section of dipmeter or image data mirrors a known underlying structural geometry (including uniform planar dips, non-plunging folds, plunging folds, doubly plunging folds and domes), it will generate a particular pattern on the plot.  Such patterns can be numerically assessed to derive geometries of curvature, and the dip (transverse) and strike (longitudinal) direction.
