There are different types of folds created by compressional stress depending on which way the rock bends. Webfolding. Folds are generally classified according to the attitude of their axes and their appearance in cross sections perpendicular to the trend of the fold. The axial plane of a fold is the plane or surface that divides the fold as symmetrically as possible. The axial plane may be vertical, horizontal, or inclined at any intermediate angle.
