Statistical curvature analysis techniques (SCAT) were introduced by Bengtson (1981) to help use dipmeter data in the analysis of folds and faults. It enables the detection and numeration of fold plunges, axial surfaces, crests and troughs. It involves tangent diagrams, analysis of azimuth and dips plots (against depth), combined azimuth versus dip plots and the projection of dip components in the strike and dip direction of identified folds (against depth). Variations in dips and azimuths, and the apparent dip components can be defined and interpreted in terms of an underlying geometry based on some simple models of curvature. Such geometries include uniform planar dips, non-plunging folds, plunging folds, doubly plunging folds and domes.
