WebLayers of rocks may be compressed only slightly or very severely during the process of folding depending upon the intensity of forces acting on the rocks. In the first case, a … WebFolding is a type of ductile deformation that occurs when rocks are subjected to compressive stress, causing them to deform and bend without fracturing or breaking. The process of folding can result in a variety of fold geometries, including anticlines, synclines, domes, and basins.

Webdeformation is more likely to result in bending or folding. Rocks containing pliable minerals like gypsum (evaporites) or clays (shales), or rocks that are deeply buried (>10 km depth) become folded when subjected to stress. There are numerous types and shapes of folds, but most can be classified into three basic types. 1.2 Types of Fold Structures WebFolded rocks get eroded just like all other rocks and the topography that results is typically controlled mostly by the resistance of different layers to erosion (Figure 12.8).
