WebParasitic foldsFolding often develops simultaneously at many scales such that smaller folds are found on the limbs of larger folds. These are termed parasitic folds, and it is common to distinguish between "first order folds" (map scale); "second-order folds" (tens or hundreds of meters) and third and higher order folds (meters to millimeters). WebTo follow the mechanics of buckle folds - start here. This sequence looks are simple buckles of single layers. But rocks contain many layers and these can interact. To see these effects, including how parasitic folds may form, click here. However, if layering is very intense, folds develop with highly angular hinges - kinks.
