Orogeny is a tectonic phenomenon involving the large-scale deformation, metamorphism, and uplift of the lithosphere that leads to the formation of mountain belts. It results primarily from plate interactions such as continent–continent collision, ocean–continent convergence, or accretion of terranes, producing crustal shortening, thickening, and crustal root development. Orogenic processes generate characteristic structural fabrics (folds, thrust faults, nappes, shear zones), regional metamorphic gradients, and magmatic activity including arc and syn- to post-orogenic intrusions. Orogenies operate over tens of millions of years, profoundly modifying regional crustal architecture, rheology, and isostatic balance, and they are central to reconstructions of past plate configurations and geodynamic evolution.
