WebRegional metamorphism occurs over wide areas of the Earth's crust. The most common metamorphic sequences in relatively young rocks (e.g. younger than 450 Ma (million years old)) occur in fold mountain belts which are produced by tectonic processes associated with the development of these belts. We call such regions metamorphic belts. WebTypes of Folds 1. Figure 10.9: Folds are a result of ductile deformation of rocks in response to external forces. 2.
