The hinge line follows the line of greatest bend, where the axial plane intersects the outside of the fold. Geologic folds are layers of rock that are curved or bent by ductile deformation. A symmetrical fold is one in which the axial plane is vertical. An asymmetrical fold is one in which the axial plane is inclined. An overturned fold, or overfold, has the … See more
