The term "Fold belt" refers to a geological formation characterized by a series of folded rock layers, which typically occurs in areas where tectonic plates converge. Synonyms for this term include "orogenic belt," "mountain belt," "fold-and-thrust belt," and "collision zone." An orogenic belt is a region of long linear geologic features that resulted from the interaction of two tectonic plates, while a mountain belt is an area of highland or mountainous terrain that formed through the action of tectonic forces. A fold-and-thrust belt is a type of orogenic belt characterized by folds and faults, while a collision zone is a region where two plates collide and cause uplift and folding of rocks.
