The Himalayan orogen is the production of the collision between continents of India and Asia. It is structurally dominated by three north-dipping, fault—bound units stacked by, from north to south, the Southern Tibetan Detachment, the Main Central Thrust, the Main Boundary Thrust and the Main Frontal Thrust<ref name=":2"/>. These units, from south to north, are:
