The Himalayan mountain range has grown over the last 55 million years as India has collided with Asia. During this process compression and mountain growth has been accommodated by rocks stacking up and sliding past each other on a series of enormous 2500 km wide shear zones. This thesis describes and interprets a complex set of movements on one of these shear zones, the Main Central Thrust Zone, where it interacts with a dome in the structure of the mountain belt. From this, an obstruction to rock flow is inferred to exist within the depths of the mountain belt.
