WebJul 18, 2013 · In crust that has been tilted, folds "plunge" into the earth's surface. Plunging Anticlines and Synclines A plunging anticline or a plunging syncline is one that has its axis tilted from the horizontal so that the fold dips into the earth. In map view, a plunging anticline makes a U-shaped or V-shaped pattern that points in the direction of plunge. WebThese folds give us features such as synclines and anticlines where Earth’s crust has folded up like an accordion as a result of compressional stress. In the case of synclines, the folds point upward from the central axis, or "hinge line", whereas in an anticline, the folds point downward from the central axis.
