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).
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)
Structural traps are formed as a result of changes in the structure of the subsurface from processes such as folding and faulting, leading to the formation of domes, anticlines, and folds. [15] Examples of this kind of trap are an anticline trap, [16] a fault trap, and a salt dome trap. They are more easily delineated and more prospective than ...

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
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.

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)
