 Abstract: Several continental slivers have rifted off the northern leading edge of the Indian plate and sequentially collided with the Asian margin – the Paleocene India-Asia collision being the last and strongest collision. Recent high-definition seismic profiling of rifted margins indicates crustal or lithospheric scale boudins in all parts of the world.  While the upper crust is highly boudinaged, a thinned and sheared lower crust fills the inter-boudin areas, which also have high thermal anomaly. 

The Himalayan Mountain, south of the Indus suture, consists of three parallel high grade metamorphic belts analogous to boudin necks separated by unmetamorphosed or lowly metamorphosed sedimentary sequences, analogous to boudins. Characteristics of Himalayan metamorphism are:

  • Presence of inverted metamorphism along the southern margin of the Himalayan crystalline belts
  • While the southern bounding faults of the crystallines are thrust-like, the northern boundary has ocean-ward dipping normal faults.
