Anticline structure.
The Pratt Anticline is weakly reflected on Lansing structure. This northeast-trending, southwest-plunging anticline is located in southern Stafford County and parts of Pratt and Barber Counties. Where the structure dies out southward, the Sedgwick Basin merges into the southern part of the Hugoton Embayment as the Northern Shelf or Northern ...
“Anticline Type” Shale Gas-Rich Structure. According to the curvature of fold turning end, the “anticline type” gas-rich structure in the study area can be divided into an arc-shaped anticline and inclined box anticlines (the two wings are relatively steep and asymmetrical, and the turn ends are flat and broad anticlines), and arc ...The model of the Alima anticline without salt was able to reproduce the observed gravity anomaly. The model incorporating salt as a diapiric structure in the core of the Alima anticline produces a negative gravity anomaly. Normal faulting along the fold crest necessarily produces the observed 2 mGal decrease in gravity between the two …The sandbox model shown below produced a doubly-plunging anticline structure, creating the interesting oval near its center. A doubly-plunging anticline is a dome-shaped fold structure associated with a localized structural high within a given layer sequence, typically related to a distinct pattern of thrust faulting beneath the localized high ...Mar 28, 2006 · GENERAL FEATURES. The structure of the area represented on Plate II (p. 78) is characterized by a prominent anticline or possibly a monocline, the axis of which is situated some distance out in the ocean, extending in a general north-south direction in places, turning slightly to the northwest. The east flank of this anticline, which underlies ... Jul 15, 2005 · The name Alma anticline has been coined recently to designate an anticlinal fold in Wabaunsee County. According to Smith and Anders (1951, p. 35): "Approximately 9 miles east of the crest of the Nemaha anticline, and parallel to it, lies the axis of a similar structure very much smaller in detail which in this report wilt be called the Alma anticline. . . . While the amount of structur
A structure symbol is shown along the axial trace. Structural Domes & Basins. Structural domes and basins are essentially circular anticlines and synclines, ...These results suggest that the Weiyuan anticline should be a thin-skinned structure and that the study region maintains a typical cratonic structure in the crust. The observed 1–2 km-thick low-velocity layer at depths of 3–4 km in the syncline area may be related to Ordovician and Silurian shale gas strata with high porosity and low density.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 in nature and develop as a response to extensional collapse of a passive continental margin (i.e. Niger Delta, Mississippi Delta). Their main feature is that they flatten ...
The crest of a doubly plunging anticline (or any geologic structure for that matter) is referred to as the “culmination.” elongate dome which developed as the sediments have been being deposited is referred to as a pericline.

Examples include the Late Jurassic to ...
In map view, a plunging anticline makes a U-shaped or V-shaped pattern that points in the direction of plunge. (The plunge direction of the fold is the direction in which the axis of the fold dips downward into the earth). A cross-section across the axis of a plunging anticline looks the same as a cross-section of a non-plunging anticline.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. asymmetrical anticline; (B) overturned syncline. Compare the orientations of the strike and dip symbols for each fold with those in Figure the Earth (another plane) and they do so in a line called the fold axis (Figure 6). There are two symbols used to identify fold axes depending upon whether the structure is an anticline or a syncline (Table ...Other articles where anticline is discussed: petroleum: Structural traps: …most common structural traps are anticlines, upfolds of strata that appear as inverted V-shaped regions on the horizontal planes of geologic maps. About 80 percent of the world's petroleum has been found in anticlinal traps. Most anticlines were produced by lateral pressure, but some have resulted from the draping ...A structure symbol is shown along the axial trace. Structural Domes & Basins.

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. 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.
The second major category of hydrocarbon reservoirs is structural traps. Structural traps, illustrated in Figure 2.08, are related to mechanical deformations and failures of the reservoir rock. Figure 2.08a shows an anticlinal structure, or anticline. As stated earlier, the anticline is statistically the most common reservoir trap.

If the fold is rounded, the structure contours will be curved, showing U-shapes: Figure 15.An anticline is a structural trap formed by the folding of rock strata into an arch-like shape. The rock layers in an anticlinal trap were originally laid down horizontally and then earth movement caused it to fold into an arch-like shape called an anticline.
The structural history of the anticline and its northern and western surroundings are relatively well studied.
