Syncline geology
WebThe two most common types of folds are anticlines and synclines (Figure 1). Figure 1 – Common types of folds When sedimentary rock layers are folded in an arch-like manner, the structure is called an anticline. By contrast, trough-like structures are called synclines. Notice that the limb of an anticline is also the limb of the adjacent syncline.

WebFigure 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. WebA syncline is a concave upward fold in which the layered strata dip towards the center of the fold (it resembles a “U”). Folds have three main parts: a fold axis (also known as the hinge line, which is the line that runs along the nose of the fold), the axial plane (an imaginary plane that contains the hinge line and generally bisects the fold), and limbs on either side of the …
WebSep 1, 2015 · The nomenclature and geometry of folds are summarized on Figure 12.5. An upward fold is called an anticline, while a downward fold is called a syncline. In many … In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. A synclinorium (plural synclinoriums or synclinoria) is a large syncline with superimposed smaller folds. Synclines are typically a downward fold (synform), termed a … See more On a geologic map, synclines are recognized as a sequence of rock layers, with the youngest at the fold's center or hinge and with a reverse sequence of the same rock layers on the opposite side of the hinge.

WebThe syncline in Figure 13.11 is asymmetrical. The limb on the left side of the syncline slopes toward the hinge at a steeper angle than the limb on the right. If the fold is sufficiently tilted that the beds on one side have been tilted past vertical, and are sloping in the same direction, the fold is overturned (Figure 13.12).
