If the younging direction is away from the inside of the fold, then the fold is an anticline. In areas of mild deformation like the Rocky Mountain foothills, where the rocks are regionally the right way up, anticlines are antiforms; the terms can be used more or less interchangeably. Similarly, in such areas synclines are also synforms.Figure \(\PageIndex{1}\): Model of anticline. Oldest beds are in the center and youngest on the outside. The axial plane intersects the center angle of bend. The hinge line follows the line of greatest bend, where the axial plane intersects the outside of the fold. Geologic folds are layers of rock that are curved or bent by ductile deformation.An anticline fold is convex up: the layered strata dip away from the center of the fold (if you drew a line across it, the anticline would resemble a capital letter “A”). A syncline is a concave upward fold in which the layered strata dip towards the center of the fold (it resembles a “U”).Dan and Pat Billman have launched a challenge to support Geology field camp: “As geologists we know, the best geologists see the most rocks.

They are concave-upward in shape.Extensive folding is represented by a repeated pattern of anticlines and synclines. Two anticlines are always separated by a syncline, and two synclines are always separated by an anticline. One side of the fold is called the limb; a side‐by‐side syncline and anticline share a limb. Frequently, an anticline or syncline can be identified ...Anticline, Pembrokeshire. The mudstones and sandstones that you see below in Saundersfoot contain clues showing that they were laid down as muds and sands close to a river mouth during the Carboniferous Period, around 320 million years ago. Nearby there are rock layers with plant fossils and thin coal seams that were formed in tropical swamps.Synclines and anticlines usually occur together such that the limb of a syncline is also the limb of an anticline. In the diagrams above, the fold axes are horizontal, but if the fold axis is not horizontal the fold is called a plunging fold and the angle that the fold axis makes with a horizontal line is called the plunge of the fold.Nemaha Anticline--The Nemaha Anticline, probably the most famous of all Kansas structures, is a major pre-Desmoinesian post-Mississippian element that crosses Kansas from Nemaha County on the north to Sumner County on the south and extends into Nebraska and Oklahoma.

The multiple origins proposed for the Kanarra anticline in southwestern Utah as a drag-fold along the Hurricane fault, a Laramide monocline, a Sevier fault-propagation fold, or a combination of these process­es, serve to muddy its tectonic significance. This in part reflects the structural complexity of the exposed eastern half of the fold. The fold …gas reservoir, in geology and natural gas production, a naturally occurring storage area, characteristically a folded rock formation such as an anticline, that traps and holds natural gas. The reservoir rock must be permeable and porous to contain the gas, and it has to be capped by impervious rock in order to form an effective seal that prevents the gas from …Figure 9.4.1 9.4. 1: Model of anticline. Oldest beds are in the center and youngest on the outside. The axial plane intersects the center angle of bend.
