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"/>.

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:

# The Lesser Himalayan Sequence (LHS), mainly low-grade [[Proterozoic]] metasediments to unmetamorphosed rocks, which is bound above by the Main Central Thrust.<br />

# The Tethyan Himalayan Sequence (THS), mainly [[Proterozoic]] to [[Eocene]] sediments. deformed in an [[Paleogene]] fold-thrust belt.<ref name=":4">Webb, A. A.
