The Main Central Thrust is one of the north-dipping and NW—SE strike thrust faults along the Himalaya[1]. Generally speaking, the Main Central Thrust is the ductile shear zone, along which the Great Himalayan Crystalline complex was placed over the Lesser Himalayan Sequence.[2]
Geologic background
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[2]. These units, from south to north, are:
