WebFolding and surface rock patterns (Diagram by Phyllis Newbill) After erosion has occurred, geologists can use the patterns of rocks on the surface to determine where anticlines and synclines exist. In the block diagram above, the top of the block represents the ground surface and what would be shown on a geologic map. WebIntroduction. Folds are some of the most striking and spectacular features of the Earth’s crust. In most cases, folds form where layered rocks have been shortened. Folds are very common, therefore, in – regions where the Earth’s lithosphere has undergone shortening as a result of plate movements. Orogenic belts often form mountain ranges.
