Bookmark or Share- Fold (geology) - WikipediaThese folds were produced by Alpine deformation. In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved ( "folded") during permanent deformation. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds.
- Fold | Definition, Types, & Facts | BritannicaThree forms of folds: syncline, anticline, and monocline. folding. Folds, progressively decreasing from left to right in the inclination of the axial plane.

- Folds: Bending to Earth's Will - ArcGIS StoryMapsFolds with interlimb angles of 70⁰-30⁰ are termed tight folds. Folds that have distinctively acute angles in outcrop are generalized as tight folds. Lastly, folds with angles of 30⁰-0⁰ are termed isoclinal folds. These folds look extremely acute in outcrop to the point that both limbs are nearly parallel to each other.
- 1.5: Folds - Geosciences LibreTextsFolds 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 orogenic belts – regions where the Earth’s lithosphere has undergone shortening as a result of plate movements. Orogenic belts often form mountain ranges.
