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.
River anticline. 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]
Rollover anticlines are anticlines related to extensional normal faults. They must be differentiated from fault-propagation folds, which are associated with reverse faults. A rollover anticline is a syn-depositional structure developed within the downthrown block (hanging wall) of large listric normal faults. Such faults are typically regional ...
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.
The structural pattern within the region shows a series of anticlines and synclines that plunge towards the core of the belt. Synclines are the dominant folding structure within the region. However, there is a major anticline, called the Onverwacht Anticline, located in the central portion of the BGB. [6]
Weald Basin. The Weald Basin (/ ˈwiːld /) is a major topographic feature of the area that is now southern England and northern France from the Triassic to the Late Cretaceous. Its uplift in the Late Cretaceous marked the formation of the Wealden Anticline. The rock strata contain hydrocarbon deposits which have yielded coal, oil and gas.
A cross section of the Peak District showing the structure of an eroded dome The Derbyshire Dome is a geological formation across mid- Derbyshire in England. Geology Map of the Peak District The White Peak area of the Peak District is named after the limestone plateau landscape of the 'Derbyshire Dome' anticline. The plateau is generally between 200m and 300m above sea level. This limestone ...
The Sawatch Uplift / s ə ˈ w æ tʃ / [1] [2] is a prominent geologic anticline in the Rocky Mountains in central Colorado in the United States. It was formed as a bulge in the North American Plate approximately 70–65 MYA during the Laramide orogeny that created the modern Rocky Mountains. The uplift runs north–south for about 100 miles ...
