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. WebGeologic structures are usually the result of the powerful tectonic forces that occur within the earth. These forces fold and break rocks, form deep faults, and build mountains. Repeated applications of force—the folding of already folded rocks or the faulting and offsetting of already faulted rocks—can create a very complex geologic picture that is difficult to …
