The origin of fold axes oblique to the regional attitude is interpreted in terms of rotation of the axes due to stretching within the axial plane of the folds. Fold axes originally sub-parallel to the Y-axis of the finite strain ellipsoid rotate towards the X-axis upon further deformation. Equations are derived for the resulting frequency distributions of oblique fold axes for both stretching normal and oblique to the original fold-axis mean. An example of anomalous fold-axis trends from north Cornwall, England is analysed using the proposed models and some other examples of fold-axis distributions amenable to this model treatment briefly discussed.
