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 the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge.
Anticline, in structural geology, an anticline is a fold that is convex up and has its oldest beds at its core; Anticlinal, in stereochemistry, a torsion angle between 90° to 150°, and –90° to –150°; see Alkane_stereochemistry; Anticlinal division (botany)

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 ]
The result is an anticline feature in a completely extensional setting. As rollover anticlines develop during sedimentation, each layer typically shows thickening toward the controlling fault. As the underlying layers bend, they create more accommodation space along the controlling fault versus the crest of the anticline.
The Weald–Artois Anticline, or Wealden Anticline, is a large anticline, a geological structure running between the regions of the Weald in southern England and Artois in northern France. The fold formed during the Alpine orogeny , from the late Oligocene to middle Miocene as an uplifted form of the Weald basin through inversion of the basin.
Huangling massif exhibits an asymmetric dome shape striking to the north-south orientation. The north and south sides of the Huangling Anticline dip gently while the basins on the eastern flank and western flank of the dome have different dip angles. Zigui Basin, which is to the west of the Huangling Anticline, dips moderately at 40° westward.
