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 water-insoluble hydrocarbons can accumulate at the crest until the anticline is filled to the spill point (the highest point where hydrocarbons can escape the anticline).
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
Formation of a river anticline by river erosion and the associated isostatic rebound. As the river erodes the overlying material, the underlying rocks will rebound up, like a block in water if you remove a weight from on top of it, forming an antiformal structure. (Image created by Michael Stevens)
A petroleum trap. An irregularity (the trap ) in a layer of impermeable rocks (the seal ) retains upward-flowing petroleum, forming a reservoir. Petroleum or crude oil is a naturally occurring, flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights, and other organic compounds, found in geologic formations ...
Column 4 indicates on which 1:50,000 or 1" scale geological map sheet published by the British Geological Survey (BGS) the fold is shown and named (either on map/s or cross-section/s or both). 'E&W' signifies the series of sheets published to cover England and Wales.

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 ]
