New tectonically active zone in Himalayas could alter quake study

News: Scientists from Wadia Institute of Himalayan Geology(WIHG), Dehradun, have found that the Indus suture zone of Himalayas that was conventionally thought to be locked is tectonically active.

 

Facts:

  • Indus Suture Zone: It is a suture zone in the Ladakh region where Indian and Asian Plates join.
  • Geological Features that proves Indus Suture Zone is Tectonically active:
    • Sedimentary beds are tilted and thrust broken.
    • Rivers are associated with uplifted terraces.
    • Bedrock shows brittle deformation at much shallower depths.

 

Additional Facts:

  • Suture Zone: It is a linear belt of intense deformation where distinct terranes or tectonic units with different plate tectonic, metamorphic and paleogeographic histories join together.
