An orogenic belt is a region of the Earth’s crust that has been deformed and uplifted during an orogeny, resulting in the formation of mountain ranges. These belts are characterized by complex geological structures, including folds, faults, and metamorphic rocks, and are important for understanding the tectonic evolution of continents.
