In the folds can define a number of elements: edges (each of the
surfaces forming the fold), the hinge (line joining the two flanks) and the plane
or axial surface (plane formed by the union of the hinges of all layers).

In view of its morphology folds are classified as Anticlines, when presented in
its core older materials and synclines when present in the core material
more recent.
