WebSep 7, 2024 · The fold axis may be the line along that the bending occurs and it is in which the axial plane intersects the folded strata. The hinge line follows the road of finest bend inside a fold. The 2 sides from the fold would be the fold braches. Anticline. Symmetrical folds have a vertical axial plane and limbs have equal but opposite dips. WebThe plane that splits the fold into two halves is the axial plane. (9 Crustal Deformation and Earthquakes – An Introduction to Geology, n.d.) Symmetrical folds have mirrored limbs across their axial planes. The limbs of symmetrical folds are inclined at the same but opposite angle, indicating equal compression on both sides of the fold.
