Anticline with syncline visible at far right- USGS

In structural geology, an anticline is a Fold (geology) that is convex to the youngest beds—youngest sediments are on back of hand, older under the palm. On a geologic map, anticlines are usually recognized by a sequence of rock layers that are progressively older toward the center of the fold. The strata dip away from the center of the fold. If an anticline plunges (i.e., is inclined to the earth's surface), the surface strata will point in the direction of plunge.(Monroe and Wicander, 230) An anticline that plunges at both ends to form a circular or elongate structure is a dome. An elongate dome which developed as the sediments were being deposited is referred to as a pericline. Image File history File links Anticline. ... Image File history File links Anticline. ... Structural geology is the study of deformation of rock including breaking (fracturing and faulting) and bending or folding. ...

In mathematics, an object is convex if for any pair of points within the object, any point on the straight line segment that joins them is also within the object. ... Sedimentary, volcanic, plutonic, metamorphic rock types of North America. ... This article is about the geologic use of the term, for other uses see Stratum (disambiguation) Interstate road cut through limestone and shale strata in eastern Tennessee In geology and related fields, a stratum (plural: strata) is a layer of rock or soil with internally consistent characteristics that distinguishes it... Strike and dip refer to the orientation or attitude of a geologic feature. ... In geology, a dome is a deformational feature consisting of symmetrically-dipping anticlines; their general outline on a geologic map is circular or oval. ...

Anticlines are typically flanked by synclines although faulting can complicate and obscure the relation between the two. Any fold whose form is convex upward, is an antiform, and most antiforms are anticlines. Folds typically form during crustal deformation as the result of compression that accompanies orogenic mountain building. In geology, a syncline is a type of fold that involves an upward slope to either side. ... Old fault exposed by roadcut near Harrisburg, Pennsylvania. ... Orogeny is the process of mountain building, and as such is both a tectonic structural event, a geographical event and a chronological event, in that orogenic events happen within a time frame, affect certain regions of rocks and crust, and cause distinctive structural phenomena and related tectonic activity. ...

Anticlines are favored locations for oil and natural gas drilling; the fuel's low density causes it to filter upward to the highest parts of the fold, until stopped by an impermeable layer. Natural olive oil Synthetic motor oil Oil is a generic term for a chemical compound that is not miscible with water, and is in its liquid state at common ambient temperatures. ... Many stoves use natural gas. ...
