WebThe continuing displacement is accommodated by formation of an asymmetric anticline-syncline fold pair. As displacement continues the thrust tip starts to propagate along the axis of the syncline. Such structures are also known as tip-line folds. WebGeologic folds are layers of rock that are curved or bent by ductile deformation. Folds are most commonly formed by compressional forces at depth, where hotter temperatures …

Folds are best displayed by stratified formations. They may be inferred from various kinds of data.

WebA detachment fold, in geology, occurs as layer parallel thrusting along a decollement (or detachment) develops without upward propagation of a fault; the accommodation of the strain produced by continued displacement along the underlying thrust results in the folding of the overlying rock units. As a visual aid, picture a rug on the floor. Webuplift, in geology, vertical elevation of the Earth’s surface in response to natural causes. Broad, relatively slow and gentle uplift is termed warping, or epeirogeny, in contrast to the more concentrated and severe orogeny, the uplift associated with earthquakes and mountain building.

WebFold mechanisms - buckle folds. Buckle folds are extremely common. They form when layers are compressed along their length. These structures have been studied for many years. You can even make your own - by squeezing plasticene layers in a vice or between your hands. To follow the mechanics of buckle folds - start here.
