Cross-sectional diagram of an anticline Anticline exposed in road cut (small syncline visible at far right). Note the man standing in front of the formation, for scale. New Jersey, U.S. In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is
Includes strike and dip, vertical strata, horizontal strata, anticline axis, syncline axis, plunging anticline axis, plunging syncline axis, and strike-slip fault. For more details and symbols, see the FGDC Digital Cartographic Standard for Geologic Map Symbolization at the official website
Anticlinal traps are formed by folding of rock. For example, if a porous sandstone unit covered with low permeability shale is folded into an anticline, it may form a hydrocarbons trap, oil accumulating in the crest of the fold. Most anticlinal traps are produced as a result of sideways pressure, folding the layers of rock, but can also occur ...
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 ]
For economic geology such as petroleum and mineral development, as well as research, modeling of structural geology is becoming increasingly important. 2D and 3D models of structural systems such as anticlines, synclines, fold and thrust belts, and other features can help better understand the evolution of a structure through time.
Strike and dip shown alongside cardinal directions on a horizontal plane. Z: strike line of the red plane, σ: strike angle, F: dip direction, φ: dip angle. The angle of the intersection with the green plane is the red plane's apparent dip in the northward direction

The diagram shows drainage pattern (a) before and (b) after lateral fold growth, as well as a 3D view of asymmetric drainage pattern. Strong erosion of river onto bedrock has preserved the old drainage valley at upper course and thus some of the first-generation drainage channels are inherited and linked with the present drainage channels.
