Enter Anticlines and Synclines. • Anticlines and syncl 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.Diagram of a syncline and an anticline. Characteristics. On a geologic map, synclines are recognized by a sequence of rock layers that grow progressively younger, followed by the youngest layer at the fold's center or hinge, and by a reverse sequence of the same rock layers on the opposite side of the hinge. If the fold pattern is circular or ... Anticlines – these folds have the oldest beds in the middle, with Symmetrical folds These result in anticlines and synclines; Asymmetrical folds These have one limb that has a steeper dip than the other. Overturned folds These occur when both limbs dip in the same direction. This condition exists …Anticlines and synclines are geologic structures that are essentially folds that occur in the surface of the earth. Anticlines are the high parts of the folds, with crests and sides that dip downward. Synclines are the low parts of the folds, or the dips. Both anticlines and synclines can often be seen in the rock layers of a cliff. A Plunging Anticline. Structural domes and bas
