WebAnticlines are a common fold type found in the Earth’s crust. When upright, the limbs (flat inclined surfaces) of these folds dip away from the axial surface (the plane intersecting the maximum curvature of the fold) to form a concave-downward structure. More generally, any type of fold that has this geometry is called an antiform. Web(c) Overturned Folds: Axial plane is inclined and both limbs of the fold dip in the same direction. 5. In general, the greater asymmetry in the fold, the more intense the deformation. 6. Figure 10.14: When folds plunge into the earth, they essentially disappear from the surface.
