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. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold.
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
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.

Structural elevation along fold crest should decrease along the growth direction of a fold because the older part of a fold experiences more uplift than their younger counterpart [33] [7]. However, this can be strongly misleading in active erosional environment where erosion rather than uplift due to fold growth is the dominant shaping force of ...
Anticlinal trap. An anticline is an area of the subsurface where the strata have been pushed into forming a domed shape. If there is a layer of impermeable rock present in this dome shape, then hydrocarbons can accumulate at the crest until the anticline is filled to the spill point (the highest point where hydrocarbons can escape the anticline). [5]
The Chemoigut Formation consists of layers of silts and clays with horizons consisting of unrefined tuffaceous and pumiceous sandstone and fine conglomerates. The formation is exposed in three windows ruptured crest of the Chesowanja anticline. This anticline runs from north to south and the windows get numbered from one to three.
