A plunging anticline has a hinge that is not parallel to the earth's surface. All anticlines and synclines have some degree of plunge. All anticlines and synclines have some degree of plunge. Periclinal folds are a type of anticlines that have a well-defined, but curved hinge line and are doubly plunging and thus elongate domes .

Pericline also refers to a doubly plunging anticline or syncline.. Pericline is a form of albite exhibiting elongate prismatic crystals. [1]Pericline twinning is a type of crystal twinning which show fine parallel twin laminae typically found in the alkali feldspars microcline. [2]
An example cross section of an anticline with a dike cutting through, with the map of its surface expression showing strike and dip information. Cross sections are made by interpreting and extrapolating a broad range of information about a region's geological characteristics. This can include data from the surface, subsurface, and existing ...

A river anticline is a geologic structure that is formed by the focused uplift of rock caused by high erosion rates from large rivers relative to the surrounding areas. [1] An anticline is a fold that is concave down, whose limbs are dipping away from its axis, and whose oldest units are in the middle of the fold. [ 2 ]
