Deformation styles. The types of structure and the geometries formed depend on the amount of stretching involved. Stretching is generally measured using the parameter β, known as the beta factor, where =, t 0 is the initial crustal thickness and t 1 is the final crustal thickness. It is also the equivalent of the strain parameter stretch.. Low beta factor. In areas of relatively low crustal ...

Strike-slip tectonics is concerned with the structures formed by, and the tectonic processes associated with other zones of lateral displacement within the Earth's crust or lithosphere, such as transform boundaries.It is one of the three main types of plate tectonic regime (and respective plate boundaries), the others being extensional tectonics (divergent boundary) and thrust …

Fold mountains are mountains formed mainly by the effects of folding on layers in the upper part of the Earth's crust.The term is rather out of date, though still fairly common in physical geography literature.. In the time before plate tectonics became well understood, the term was used for mountain belts, such as the Himalayas.These mountain ranges are not caused by the folding of …
