WebMar 1, 2024 · Download as PDF. In geology, the terms folding and faulting refer to changes that occur below the surface of the earth. Folds constitute the twists, turns, and bends that are present in the rocks. On the other hand, fault is a detached plane formed when rocks on either side of the detachment or displacement move past each other. Folds appear on all scales, in all rock types, at all levels in the crust. They arise from a variety of causes. When a sequence of layered rocks is shortened parallel to its layering, this deformation may be accommodated in a number of ways, homogeneous shortening, reverse faulting or folding. The response depends on the thicknes… WebThe fold axis is where the axial plane intersects the strata involved in the fold. A horizontal fold has a horizontal fold axis. When the fold axis plunges into the ground, the fold is called a plunging fold. “Rock Folding” by Colin Park is licensed under Creative Commons Attribution-ShareAlike 4.0 International.
