WebApr 9, 2024 · Anticlines are folded rock formations that have an upwards convex shape. This means that anticlines look like a lowercase “n” or an uppercase “A” (“A is for Anticline” is a common phrase for remembering the shape of anticline). They form from layers of rock that were originally horizontal and relatively flat. 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.

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.
